Does anyone have recommendations for a fuel pump for a mostly stock 64 389? it looks like there are some diaphragm units that look similar to the originals,not sure if those are a good way to go? Any brand suggestions?

Thank you!

If the car is "basically stock", just rebuild or replace the original unit. The car went 50 years with the original one didn't it? That spells reliability to me.

I like the Carter street pumps.My only issue these days with buying a rebuilt one if the components are compatible with our modern fuels?Tom

Is your carburator(s), fuel lines, sender and sock all "compatible"?

I could go further and include pistons and rings.

From my tank to my carbs are,thank you for asking!Tom

Same here, it may look stock but my stuff could run on methanol without issues.

First I've heard of pistons & rings not being compatible with ethanol.

Most of us run E10 only when pure petroleum gas is not available. Here in Wisconsin, there are many retailers who have ethanol-free gas. When I'm stuck in an area without ethanol-free gas, I hold my nose and use what's available. It's not likely that the ethanol mandate/tax credits will go away any time soon.

Ethanol is the fancy technical name for alcohol. Alcohol washes cylinders of lubrication which prematurely wears rings and scores pistons. If someone is worried about the alcohol in fuel they better install moly rings and coated pistons.

If you think moly rings and coated pistons are overkill, so is over-thinking a fuel pump for a stock vehicle. Especially when there are rebuild kits on the market to rebuild your original AC fuel pump to handle ethanol. > http://www.classicpreservation.com/fuelpumpkits.html

I'm with you Dick...

There is no way that pistons and rings (IMHO) could be affected by ethanol.

The ethanol issue is with the soft parts, not the hard parts.

Ford has sold Flex Fuel Vehicles for at least 10 years if not longer. That means vehicles that can run on E-15 or even E-85.
I agree that the soft parts as well as materials used in pre-E10 and E-15 vehicle production days can have issues
(EFI Fuel pumps come to mind).
Lots of failures on those but the vehicles are over 10 years old and not under the extended warranty for those parts.

If you buy a new Carter Fuel Pump, odds are it is built with compatible materials for the fuel out there today at the pumps. A old fuel pump that has been sitting on the shelf for years but new, maybe not.

Thank you everyone especially ponyakr the links were very helpful

...check the web...they sell awesome kits to rebuild stock pumps and they have a patent on a nice flowing valve system for these that they make onsite in machine shop...prob with cheap pumps is they produce too much pressure sometimes...my chinese pump started pumping out over 8 lbs and flooding over the hot intake..fire waiting to happen...i rebuilt with their $50 kit, tested and it put out only about 5 lbs..stock pressure..i added an inline pressure valve as a fail-safe in-case pump goes bad again...don't want any fires...if in Mass check out their storefront...south weymouth area...old school retailer of many nos parts for pre 80's cars..and a great resource for used parts and kits for rebuilding various old parts...

I really don't like the Carter when compared to the original pump, The new Carter is built with a external spring to the push arm, that imo can fail and end up in the oil pan.

[Tom Vaught]

If you remove the external spring and can still maintain 6 psi to the carb, there is no reason for having the external spring, except for the manufacturer to advertise a higher pressure capability. "Spring in oil pan issue" removed.

[remy30006]

I just bought the Carter carb with the spring. Should I remove it?

[Tom Vaught]

If you take it off and it still gives you 6 psi leave it off. If it is less that 5 psi and you are in a performance mode type guy, leave it on.
I have read more about mechanical fuel pumps having too much pressure (the last few years) vs lower factory pressure.

No leave it alone , the BS if the spring breaks is a poor opinion . That spring was engineered for a reason , leave it alone .

[Jeffs64Cat]

Just brought a Carter M4566 40Gph@6Psi max pressure is what it is. According to the Carter online.
