1967 Fuel Pump

[Rick S.]

I obtained a new 67 fuel pump from Corvette Central today and the stamping on the flange is not ringing true with me. Attached is a photo that I would like to hear any comments about the stamping. I don't recall seeing/hearing about the "7E" stamped before the part number and the JG makes no mention of anything beyond 6440433.

Rick------

There are often, if not always, some characters which precede the AC type number. These are some sort of manufacturing and/or date code. I've long-since forgotten how to decode it, though. In any event, as far as your concern goes, I would have no concern.

Rick,

The first characters before 40433 are some sort of vendors code, or date code as Joe indicated. The first two characters on my original for a late 67 are "PO" or "P0".

How about posting some more pictures of it, I'd like to compare the CC one with my original. This must be a new repro, I haven't seen one listed in the previous catalogs. Here's my original:


refurbed of course.

Jerry,
Here are additional photos, please note the flaw in the casting area of the pump just above the crimped area and by the weep hole?

I think that these "reproduction" fuel pumps are actually original AC upper castings (from just about any crimped style pump) which are rebuilt using new lower stampings and internal parts. The number on the flange is probably a re-stamped number applied after the original number is somehow "obliterated".

I think that what you're figuring is a casting "flaw" is actually the result of previous corrosion which has been chemically or abrasively removed from the casting.

Joe,
Is the threaded fitting for the fuel inlet the correct configuration?.I was going to buy one of the rebuilt originals as shown in the pictures, but decided (with your help) to get a new replacement. It has a non threaded inlet with a nipple for the fuel hose to attach. The replacement AC pump which has absolutely no markings was $29 and the rebuilt original was over $100 if I remember correctly.
thanks

John,

The originals had two threaded fittings like Rick's and mine above.

When I had mine restored, I bought a cheap replacement for the base and internal parts. The replacement base had a non-threaded inlet. My restorer took the inlet fitting from my original and brazed or welded it to the replacement base.

The fitting looks pretty close to the way it should from what I can see of it. Of course, the pump does not have the elbow fitting which is a separate part.

For a driven car, I'm not really a fan of rebuilt crimp-style pumps. A fuel pump is a MAJOR safety item, especially in a Corvette. Due to the fact that the pump is lower than the fuel tank, if the pump fails it will siphon gasoline out of the tank. I had this happen to me years ago with my car parked in the garage (which to make matters worse, at that house, had a water heater mounted on the floor of the garage). We woke up in the morning to a garage floor covered with the contents of my fuel tank. It makes me cringe to this day.
