This was really valuable. I do not have a dune buggy, But because you talked slowly I was able to learn something that actually helped me. Thank you sir.
David Remember if your fuel pump outlet pressure is too high, the regulator can only adjust the pressure down so much. Make sure you pressure gauge is accurate.
Thanks Milo. I bent the spring to get the regulator to lower pressure by making it shorter overall, just like what you experienced. I got it to the proper pressure, 3 psi, but it still leans out at light throttle. The hunt continues.
Had a Holly fuel pressure regulator with the same problem they’re trash same design I remove the spring and collapsed it into itself to make it softer after that it worked perfect the springs are too stiff
Hello Milo,brilliant vid//I have a 1970 bug with a Solex 30 PICT 2.I fitted a low pressure electric fuel pump but the bug won't start// what would be the problem if the fuel pressure was too high?
No matter what the fuel pressure, it should start and run. Check your basics. An engine needs spark, compression and fuel to run. Then adjusted and fine tuned for optimum performance. If your getting too much fuel pressure, it wears hard on the needle and seat and will eventually over flood the carb.
Hi again Milo//It'll now run bit only on a carbs worth of gas//the plugs,points,ignition timing have been done(timed statically obviously)//the carb has been stripped and blown through(twice)but each time I put the carb back on it'll run for a carbs worth of gas and cut out//I've taken the top off the carb and there's gas in the float chamber//strange
I just saw you put an electric pump on it. I would not have used an electric pump. Too much pressure. What is your fuel pressure? Take a reading between the pump and carb. Do you have a pressure regulator on it and can you adjust the pressure to below 3psi? Your missing something. You must have an understanding of how things work and why.
Thank you Milo. Your video inspired me to install a regulator as I was getting fuel dripping into the carburetor after the engine was turned off. I have a Manx Dune Buggy with a Solex Pict 2 carburetor. I bought the Holley 12-804 fuel pressure regulator that has a range from 1 to 4 PSI and took a pressure reading of my fuel before installing it. It read 4.2 at idol. After I installed the regulator, I could not bring the pressure down below 3.8. Do these readings fall within what you were getting before changing the spring inside your regulator?
Daniel, First, are you using a quality, accurate fuel pressure gauge. When ever I had 6.0psi or lower I could always lower the pressure to 2psi without the spring change. Having 4.2psi w/o the regulator means something is wrong. Is there something blocking the fuel feed line? There are things you need to check. Watch my "Fuel pumps Alternator Generator video"
Milo, thanks. I have an old gauge that is probably a cheaper model. I found the Kodiak Controls KC25-5# Low Pressure Gauge 5 PSI on Amazon that looks like yours and has good reviews. I think I will purchase a quality gauge before I move forward. My fuel lines are new and the carburetor is rebuilt (restored). I am probably getting higher pressure than what the gauge is showing. I will watch your other videos. Thanks again. I will let you know how it goes.
Your "Fuel pumps Alternator Generator video" is very informative. You explained the difference between the two kind of pumps and rods very well. My motor has a generator fuel pump, but has an alternator installed. I was very confused on which pump to buy. When I watched your video a few month ago your information saved me a lot of grief and returned parts.
Hi Milo, where can i buy that fuel pressure regulator? I have a Malpassi King filter regulator. If you take a glicerine manometer you will have better precission (less oscilation). I like si much your videos. Regards from Gran Canaria (Canary Islands)
I have a Chevy 350 with Holley 4 barrel 80457-2 with electronic ignition. Problem is losing power going up San Francisco hills. No surging, but loss of power and think maybe car is flooding out. Starts great, idles nice. Just barely can get up hills. Am going to replace fuel filter and fuel pump too. Help?
Hi Milo, is the pressure regulator just used for the electric pump or can I use it with a conventional mechanical brosol pump? 00-9102-0 is model I have. Thank you.
Jamin Found one on Ebay, here's the link: www.ebay.com/itm/2-1-2-Marshalltown-Pressure-Gauge-NSN-6685-01-111-8352-0-5-PSI-0-34-Kilopasca-/371548202482?hash=item5681ffa5f2:g:tpoAAOSwL7VWtMyt My search was: 0-5 psi PRESSURE gauge 2 1/2
Just curious, it has been almost 3 years since you made this video. How is the regulator working for you? Please let us know. Thank you! Great video, by the way.
Mauricio I have had no problems whatsoever with the regulator. It still delivers the pressure I set it to and have had no carburetor or engine problems. It's the way to go! Wow, time flies. Thanks.
3/8 pipe to 1/4 hose I used two fittings for the connection of the 1/4" fuel line. I think Summit racing sells a single fitting that goes from 3/8 pipe to 1/4 hose. I bought the fittings in the video at Ace Hardware.
My engine is a fuel injection block. I have to use an electric fuel pump.I bought a Redline for Weber regulator. I have a Progressive 2 BBL Weber carb.The man that built the 1776 engine told me to run the fuel pressure at 2-2.5.
I have a new carb, new pump,new rear fuel filter and fuel filter under the fuel tank. The filter in front fills up, but the rear filter is only half full until I rev it up then the pressure fills the rear filter. How do you make the pressure go up a lil more?
Why do you think you need more pressure to fill up the filter? Most of those cheap filters you can see through, always have air pockets. I suggest you check your fuel pressure going to the carb and change your filter to one you can't see through.
factory mechanical pump outs out from 0-10psi i was told? so how much psi do I need for webber44? is only putting out 3psi. can I do some trick to the rod. in the pump tu pump out more?
Jerry Assuming your fuel pressure gauge is accurate, the Weber IDF 44's run best at 3.0 to 3.5 psi. Of course the idle mixture screws, the float level and jetting must be correct. You will not run lean at W.O.T. at 3.0psi. Most aftermarket mechanical pumps put out 6-10 psi.
MILO MANX T-1 pumps will but T-4 engine mechanical pumps rarely if ever put 6-10 psi out. The 72-74 T-4 buses came with dual Solex carbs from the factory and the mechanical pumps would run them without issue fine. Going to dual IDF's is a simple swap.
No, fuel pumps are designed to handle different volumes and pressures. Think of the engine at 6,000 rpm and leaving of the accelerator. Besides, the 6psi strain on your carburetor's needle and seat and the over rich condition it causes is more important to address.
Do you know this from personal experience? The Quick Fuel regulator I use says 1-4 also. Let me know what pressure your pump puts out, before the regulator and see if you can get your pressure down to where it has to be.

Thank you, I am working on my Father's '71 Super Beetle and this is just what i need!! Thanks a million!!
With only a few more parts you could have made regulator bleed off to return line back to tank reducing fuel temp and vapor lock
Nice vid thanx.
Great video. it just so happens I'm doing my fuel system at the moment on a new engine installation. This is valuable information thankyou.
Good Job. I will do a bit of research as well. Thanks Milo
thank you for this. my Spectre brand (Autozone) regulator has been fooling me and I've been chasing the wrong problems for months

Freddys Nava Yes, definitely on mechanical pumps, just like in the video. Make sure you have a good oil pressure gauge.
Thanks for your help Milo. Greetings from Venezuela
thanks man, great info.
Hi, Could you please tell me what brand the gauge is and where where you purchased ?
In struggling to find a 5psi gauge in my country. Thanks

Mauricio I have had no problems whatsoever with the regulator. It still delivers the pressure I set it to and have had no carburetor or engine problems. It's the way to go! Wow, time flies. Thanks.
You rock, sir. I also noticed you have since changed the pressure to 2. 0. Thank you and nice Harley!
What fuel presure if its turbo 8lbs ? and WOT 3rd and 4th gear has a couple pops out exhaust
Do you know the pressure for dual 34 mm carburetors?
The regulator came yesterday. Please include a list of the names of the fittings used in this video. thanks!
3/8 pipe to 1/4 hose I used two fittings for the connection of the 1/4" fuel line. I think Summit racing sells a single fitting that goes from 3/8 pipe to 1/4 hose. I bought the fittings in the video at Ace Hardware.
My engine is a fuel injection block. I have to use an electric fuel pump.I bought a Redline for Weber regulator. I have a Progressive 2 BBL Weber carb.The man that built the 1776 engine told me to run the fuel pressure at 2-2.5.
Look up the carb's recommended fuel pressure on a Weber website. My experience with dual Webers are 3.0 to 3.5. Is that your question?
Almost, Thank you for replying. My carb is a 2 bbl. Weber Progressive. I will look on the Weber website.
Thank you. I found that Weber recommends 2.5.
Great info.
I later went back and adjusted the fuel pressure down to 2.0psi. Sometimes you get brain overload!
There are some that recommend setting the fuel pressure at 2.5psi. Is 2.0psi the optimal setting for our bugs? Thanks.
I have a new carb, new pump,new rear fuel filter and fuel filter under the fuel tank. The filter in front fills up, but the rear filter is only half full until I rev it up then the pressure fills the rear filter. How do you make the pressure go up a lil more?

can this regulator be used on an electric fuel pump?
Yes, Make sure it is a low pressure pump. Get a good pressure gauge to know the p.s.i.
Would adjusting the fuel pressure from 6 psi to 2.5 psi for my Solex 34PICT3 carb put too much strain on the Brocar fuel pump diaphragm?
No, fuel pumps are designed to handle different volumes and pressures. Think of the engine at 6,000 rpm and leaving of the accelerator. Besides, the 6psi strain on your carburetor's needle and seat and the over rich condition it causes is more important to address.
Milo Holly makes a 1-4 psi regulator that works without modifications
Do you know this from personal experience? The Quick Fuel regulator I use says 1-4 also. Let me know what pressure your pump puts out, before the regulator and see if you can get your pressure down to where it has to be.
MILO MANX
12-804 is the model I use it 12 psi before and I have mine dial to 1.75 after I am running a 28 pict-1 on a vw1200
But the idea of a regulator has helped me out so thanks for the video and I do owe you a dollar😀
