My truck: 1954 Chevy 3600 with original 235 engine with Rochester carb & 4 speed.
Rebuilt to stock specs.

Questions have to do with my AC nos Fuel Pump.

see photo of the fuel pump below @ photobucket.

I've been told that today's modern fuels with ethanol will eat up the original fuel pump diaphragm ?

If this is true...how do you work around it ?

I'd rather update the fuel pump than install it out of the box and then run into problems later with today's fuels.

Any suggestions ?

If replacement parts are needed...I'd need a source for those parts.

Need some experienced opinions.

Thank You,
George

I do not have an answer to your question however if you want to keep that style i just bought one from patrick's. Even better you might want to give patricks a call i bet he would know.

Here's an answer I received from a guy that does carb & fuel pump rebuilds.

I'm sharing his answer here.

Any opinions about what he says ?

Read what he says, below.


Good morning, George. Thanks for visiting.

The NOS parts are great in terms of the fact that their mechanical
tolerances are as-original. However, in the case of fuel pumps and
carburetors, none of them have gasoline contact materials in them that
will withstand today's alcohol-based fuels.

I recommend that you consider either rebuilding the pump yourself with one
of my kits or have me do the restoration for you with modern materials
that WILL withstand today's fuels.

Should you choose to do the rebuild yourself, you would need to order my
new-production, made in the U.S.A. kit #FPK 131 at $38.00, plus $8.00
shipping. The cost to have me restore your pump is $135.00, plus $14.00
shipping. The restoration includes attention paid to mechanical and
appearance aspects. It also includes a 2 year warranty.

If you haven't already done so, you may want to see pictures of fuel
pumps I have restored. To do that, click on this link:

I sent Harold a photo of my NOS AC Fuel Pump.
I wanted to know for sure if his kit would
work with my fuel pump.

Here's what he says, below.
At the bottom, my email to him.



Yes, George. Kit #FPK 131 is the kit for that pump.

Let me know if you'd like to order the kit.

All the best.

I started to think about the Rochester Carb I rebuilt with a nos oldtime carb kit.

Here's my email to Harold.

Harold, What do I need to do to the carb. I dis-assembled the carb.

Cleaned it whistle clean. I then put in a Rochester NOS carb rebuild kit.

The kit was about ( 50 ) years old.

I'm now thinking........YOU have other ideas about my carb.

I've have not run the carb or fuel pump yet.

I'd rather re-do the carb then have problems later.

May I request your solution for my carb.

Do you have any kits that will work for the modern fuels ?

George

Here's his answer.

Hello George;

If I were in your shoes, I'd go through that carburetor again with my
new-production, made in the U.S.A. special order kit #323 at $59.00, plus
shipping. All the materials in this kit are designed to withstand today's
alcohol-based fuels. The "special order" simply means that you could
expect to receive the kit 5 to 6 days after my receipt of your paid order
for it. If you had me hold the fuel pump kit until the carburetor kit was
ready, then the order would be $38.00 for the fuel pump kit, plus $59.00
for the carburetor kit, plus $8.00 shipping, for an order total of
$105.00.

I'll wait to hear back from you.

Take care.

I had a buddy rebuild my Galaxie carb and I installed new fuel pump and new lines (had been sitting for decades), got it running, everything was shot in 2 years (rubber diaphrams, rubber lines swollen and soft). The replacement Holley I ordered had a tag metal banded to the new carb "use with ethanol based fuels voids any/all warranty". I had to clean out gas tank and install new rubber lines on my chevy II due to what I presume is ethanol (with stabil in tank, but not the "new" version for ethanol). Every pro I speak with from small engines to mechanics cuss ethanol with every breath and so do I. ask small engine guys about weedeaters and chainsaws that have tiny rubber lines that sit in the tank what happens to them due to ethanol additives.
