Teflon tape doesn't work for fuel sealing. It will break down, wash out, and the fuel will leak though the threads. Found that out the hard way the first time I installed an electric fuel pump.
@@axlsnakedogthe last time when it started leaking around the fittings I used black permatex #2 and it seemed to seal it up very well. I just used the same thing not 30 minutes ago putting my new regulator on. I guess I will put the pump in next weekend if my wife will even let me work on it then, haha.
Is that holley red pump still working without any issues? I had run those in the 90's with no problem. Decided to run one again about 6 yrs ago and didnt last a month before failing....
Hi, Iam wondering why you using a fuel pressure regulator. According to holley it is not required for the red pump. I am asking because the preowner of my Camino installed a red pump too and a regulator. Sadly before the fuel filter and not after the filter. So I try to figure out if I should switch the order of regulator and filter (makes sense) or just to remove the regulator at all. Thank you for your thoughts.
Very good question! And yes with the holley red pump you don't really need a pressure regulator because they only make about 5 to 6 psi max, which is about what a factory mechanical pump makes. This should be fine on an el Camino which prob has a Rochester Q-jet for a carb. On the flathead however the mechanical pump only made 3 to 4 psi (sometimes less) and the stromberg 97 carbs or even the holly 94 carbs only need 2 to 3 psi. One more reason to run a pressure regulator (and even a return line to gas tank) is surging or over pressure, mechanical pumps are driven off engine speed, so when fuel demand is low at idle the pressure also drops a bit, and as you rev the motor and fuel demand increases so does the pressure, with an electric pump however pressure is always maxed at 5 to 6 even at idle. A regulator is always a good idea and provides adjustment to tune your fuel pressure perfectly and to prevent over pressure at idle. Also a return line (which I still need to install) is not really necessary for low pressure applications, but is still a good idea especially with ethanol fuels. This will prevent percolating of the fuel and eliminate pressure surging and give your carb a cool charge of fuel in all situations.
Thank you for the watch and I hope this helps. In my application I ran the filter just after the pump as you saw, and I wanted to run another filter before the pump as well to protect it from any sediment or gunk in that old gas tank but I was concerned because a vien pump (holly red is a vien not a pulse) pushes only. This means only gravity will push fuel through a filter before the pump so I didn't run one, even tho a few people I asked said you can.i was worried about air getting behind the pump and causing more noise from the pump and premature wear.
@@axlsnakedog Thank you for your expertise. I run a Edelbrock 1806 (650cfm). My options are put the fuel filter before the regulator or just remove the regulator at all. Dont know
@fuelbasti that model edelbrock should have a filter on the carb at the fuel line inlet if not just run a clear filter (wix makes a good one thats cheap and looks cool) just about 6inches to a foot before the regulator should work best

Thanks man! I learned something new awsome!
What do you recommend, i was tempted to use a brushable putty like i mentioned in the video but tape was what i hsd on hand

Thanks for posting these vids! Keep the hobby going and all the hard work!
More to come!
Thank you for the comment you made my day!

@fuelbasti keep your regulator as long as its working good, for that carb i would set pressure between 3.5lbs to 4.5lbs max
Run off a fuel cell?
nope gas tank trying to keep original vibe as much as possible
