Part 5: 1938 Buick - 1930's-1950's GM Fuel Pump Rebuild

[@veraginacci]

I live in Texas, just purchased a 1948 Cadillac series 62 I think. Original motor and all. Flat head 5.7 V8.
I’m so happy I found your video.
I used to travel all the time to Lawrence as soon as I saw your name I knew 😂

[@RobbiRocks]

Sooooo very helpful all of this, And thanks for having No annoying back ground music, Cheers

My 52 has that same fuel pump, likely original. Wish it had that screen.

[@paulk3533]

I totally agree with keeping it all original. Keep the connections clean and tight and all cables in good shape and you won't have any problems.

Fuel pump looks great, beautiful Buick.

Sometimes people dont like change. Even if it would be to their benefit. Been working on a AC 405 B pump off a 31 Chev. The casing broke at the mounting bolt. Ended up replacing the pump with a rebuildable. Used all my parts I currently had in unit since it wasn't long ago since I rebuilt it. Anyways finally got around to reinstalling but can not get it to pump the gas. I used compressed air to fill the lines and bowl. Left the output side disconnected so I can confirm the pump. BUT....I am getting nothing. I am aware of the two valves in there and admittedly didn't think to confirm they moved. I had removed and cleaned them. I can see the diaphragm stretch so I am thinking that maybe its going to need a replacement. Everything is tight but maybe still not sealing. Open to anyone's thoughts. Due to the season change and the need for the garage I put it away for now. Thanks

I too agree with keeping it original. Nothing wrong with six volts systems as long as the right cables are used and the connections are clean (as you stated in the video).

My 54 Chevy Blue Flame 235 had the same type of filter in the fuel pump. It was a vacuum boosting fuel pump with the glass bowl facing up. I have seen this type of filter in several 40's and 50's vintage farm tractors as well as on the fuel tanks of single cylinder engines for garden tractors. I've also seen them in much larger Diesel filter units. It makes me wonder if they were best used in heavy duty applications as well as applications where fuel was potentially chronically dirty. Though it takes time, they are easily cleaned and far better than a sediment bowl alone, which would have been the alternative at the time. Thanks for the memories, by the way. . .

[@kimkramer5773]

Like your vids. My opinion is, fuel pump is up side down, Stroke on arm make contact at the same point on the cam. Rotate the bowl side 180 and will reset in and out. sediment should fall to the bottom of glass bowl, not fall into diaphram area. And makes it easier to install as well.

[@TheJayhawker]

It seems that way, and usually that's the way a sediment bowl is, but according to everything that I have ever seen on this style of pump the bowl goes on top. Thanks for watching!

Nice video,

[@tombob671]

Denatured alcohol will dissolve most varnishes too 👌

[@danellis548]

A great video and a really good series. I was wondering how you pressurized the fuel line?

[@TheJayhawker]

Simply by putting a blowgun in the gas filler and stuffing a rag around it. Go to my channel or type this in UA-cam search : "1948 Chevy First Start & Drive in 32 Years!" In that one I show exactly what I do.

[@spymaine89]

what vibration would cause the glass to shatter.......

[@cocopublicnews6766]

I had a huge argument with the sales person it wasn't my pump mine was the duel action

[@BradSearcy]

This is going to be a really dumb question, but I inherited this car (1947 Buick Series 70) and I need to replace this fuel pump. I'm just going to go with a remanned part, but I assume that I'll need to drain the oil out of the engine to do this part replacement? Just trying to cover all my bases before i dive in. Thanks in advance.

[@TheJayhawker]

No, the fuel pump is higher than the oil pan so all you should expect is a little residual oil around the lever when you pull it off. No worries!

[@oddlyrightoddlyright2475]

Nah man better running gear just make for a better ride….I’m building a 1940 torpedo body Buick special it was my uncles it was beautiful in the 90s it’s all but rotted away now lucky for me I was on face book and found a two door that’s better than my four door 351w and a c4 my plans are to literally rattle can a olive drab paint job and dump a 4 inch pipe out the passenger fender off a turbo…..I’m going to DRIVE the car hard and get all my smiles out of it before we get ushered off this planet.

[@AndysDogHouse]

Hey Jayhawker. Good video. I have to rebuild the fuel pump in my 1940 Buick Super Eight. Could you tell me where you purchased the rebuild kit for your pump. Oh, I am keeping my car all original. Yes 6 volt.

[@TheJayhawker]

Hey sounds great, always prefer to keep 'em original. In this case I just searched for a kit on ebay.

[@dsim9988]

I have the same fuel pump filter without those thin brass washers that have the castle style ridges. Mine just has a screen. Mine came out of 216 inline six GM. Where May I ask you bought the rebuild kit from? Also, would I be able to use that on a 235 inline six GM? Thanks for the video.

[@TheJayhawker]

I think I bought that one off of ebay.

[@bluzmanintx8176]

I noticed you use permatex instead of the black rtv silicone that I always use. Why do you prefer that?

[@TheJayhawker]

Honestly the biggest reason is that I have been using it or watching my dad and grandpa use it for 40 years. It's just a product that I know and trust. The next reason is that I feel it makes for much neater and cleaner installs. You don't get the usual rtv "squish." So a general rule for me is that if I'm sealing machined or true surfaces together or sealing threads I use permatex. If I'm sealing pieces that require a thickness to the sealer to fill gaps I use RTV. Thanks for asking!

[@jamescaneda9515]

Where did you find parts to rebuild your fuel pump? I haven’t found anyone selling kits to rebuild fuel pumps.

[@TheJayhawker]

check this out: www.oldbuickparts.com/product_info.php?products_id=2027 or go to ebay and search for one, they're on there. Thanks

[@OLDTIME47]

I got 6 pumps, how much to rebuild them? 48 chevy, same as these

[@TheJayhawker]

I could probably find a rebuild kit a little cheaper, but at a parts house I use they list them at $75.00 each. Plus about an hour labor, we're at $150 each. But like I said it's possible I could reduce that by $25.00 or so. Email me [e-mail] if you're interested.

[@Mr50pop]

Not knocking your efforts because I've always wanted to rebuild my fuel pump whenever it goes bad are you saving any money buying a kit versus buying a new fuel pump I have seen the kits on eBay and they look to be kind of pricey

[@TheJayhawker]

You probably break about even provided you can find a replacement pump. But I wanted to make a video on rebuilding a rebuildable pump so there we go! Thanks for watching!
