Can original fuel pumps be rebuilt?

[D S.]

I have an original AC Delco fuel pump (40770). Can fuel pumps be rebuilt? By who and about how many dollars? I would sure like to keep the original raised AC logo on my fuel pump.

Thanks,

Scott,

I have never heard of anyone rebuilding an AC fuel pump unless it was put together with screws. Is your 40770 correctly date coded for your car?
Example: "19K 40770" where "19K" = 19th day of 1971

Heck, I don't know if it's dated correctly. I'm not crawling underneath the car to find out. All I want to do is keep from having to pay out the wazoo for another "NOS" original AC 40770. Although I do have two AC 40770s, one still in the plastic bag with original box and the other that I think was lightly used before the owner found one for his/her Corvette. Both the one in the bag and the used one have 182H40770.
Surely after everything else is rebuildable a fuel pump can be rebuilt, too.

Thanks,
Scott

Scott, paragon corvette does quite a bit of rebuilding of parts, pretty sure they can.

Re: Can original fuel pumps be rebuilt?

I know there WAS someone rebuilding the later 'crimped together' pumps as he was advertizing in Hemmings Motor News. Whether he's still in the biz or not, I can't tell you.

But, it was the opinion of both Joe Lucia and myself that this 'surgery' might be a bit risky as the body parts of these pumps weren't designed to be crimped/de-crimped/re-crimped...

Re: Can original fuel pumps be rebuilt?

Thanks. After I had sent the post I discovered I have three 40770 fuel pumps, two with the AC logos (one NOS, one used) and a newer pump without the AC logo. But I hate to throw away something like that which might could be rebuilt. Some fuel pumps keep on ticking', many don't. There is one on eBay for $175.
Speaking of crimping there is a member who claims he takes new wiper vacuum relays and pulls the caps off and installs the two finger caps and recrimps the edges. Says they looks original but functions like new. So the crimping process should be able to be done by those who know what they are doing.

Vacuum leaks on headlamp actuators will not fuel a fire like a leak on a fuel pump

Re: Can original fuel pumps be rebuilt?

No argument there. So the only way the fuel pumps can be crimped safely is by the manufacturer and no one else can safely duplicate the crimping?

I had the 215K40769 fuel pump on my '71 base engine auto rebuilt by Goat Hill Classics, 2037 W. 16th Street, Long Beach, CA 908113, phone 562-437-7664 (Paul). I reallly wasn't sure at first if he was going to do me good or not but, in the end, he did me good. They might take a little while in doing it, but they got mine done for $94.53 including shipping. They destroyed the original can (which they warned me about and it happens most of the time; sometimes an original can will be salvaged but it is more the exception than the rule) and had to crimp on a new can. This was the fuel pump that was on my car when I bought it in 1978. Current research indicates that it might not be the original pump, but I use it anyway!

Randy,

Was you car made in August 1971? I believe that your 215K40769 is dated the 215th day of 1971 or August 3, 1971.

The official build date of my car was December 15, 1970, according to the documentation recently provided by NCRS. The trim tag says E14. So it's like my car is a whole year off with regards to the fuel pump that was on it when I bought it in 1978. I know the 2nd owner from the summer of 1975 to when I bought it, but I know nothing of the first owner.

So, needing more education in the ways of fuel pumps what date is 182H40770 and how did I get two with the exact number (182H) from two different sellers within a two year period of time?

The less than $100 rebuild/shipped charge from Goat Hill is darned more reasonable than an NOS one for $175 plus shipping from auction sites. And I can retain the AC logo. Think I'll just stick the Delco service replacement on my engine if its determined that the AC one needs rebuild.

How is the best method of removing the fuel pump and installing the new one?

Thanks,
Scott

Re: Can original fuel pumps be rebuilt?

D Scott I have not replaced a fuel pump on a 454, however on my 70 SB I did use the access from the front of the block where there is a bolt that can be removed and a longer one installed lightly to retain the fuel pump rod. If the fuel pump rod is not retracted fully, the engine can be turned over to retract it as the camshaft lobe moves.
There is information in TDB archives on this and a post that mentions what timing mark indication will allow full retraction of the fuel pump rod.
Full retraction of the fuel pump rod makes installation of a fuel pump more enjoyable.

Re: Can original fuel pumps be rebuilt?

With regards to dating of fuel pumps, there is another thread on this site that talks about what is believed to be the dating process for fuel pumps. I don't recall all the details, but the "K" in my fuel pump is thought to represent the calendar year 1971. I believe "J" was 1970 and "H" was 1969 ("I" was skipped because it looks like a 1). If my thinking is right on that projection, you two "182H" fuel pumps would be seen as dated on the 182nd day of 1969. I'd find and check the fuel pump date thread to get all the real details. And, as I said before, this dating process for fuel pumps isn't hard and fast - the person(s) looking into this see trend and are carrying it forward at this point.
