What kind of after market fuel pump can be used for a stock carb?

 

Holley red works pretty good for me.

 

But you have a FPR Ian, right?

 

yes I have an FPR (fuel pressure regulator). Just tell him what you have so he can go buy a carter "el cheapo" like you have.

 

You're on a roll today, aren't you Ian.

My fuel pump and FPR in my sig.

 

Sleep deprivation helps alot with me rolling. I break my car and then come here and harass you. Its a good time.

 

Are there any benefits from going with an aftermarket fuel pump with the stock carb?

 

More volume if the engine isn't stock. Otherwise, just keep the stocker.

 

If you replace your fuel pump with an aftermarket one it gives you room for upgrading later. The stock fuel pump only barely supplied enough fuel for stock when it was new. Now that 20-some-odd years have gone by it rarely lives up to it's expectations. Add to that the fact that most people ignore their fuel filter until their car stops running properly and you have a poor fuel scenario.

Now any aftermarket fuel pump will pump too much pressure for a stock (or even a modded) Nikki. So when I installed my Mallory Comp 70, which I love so very very much, I had to install a Fuel Pressure Regulator to bring the pressure down. Most pumps give out abotu 6psi, and your carb needs to see about 2.5-3psi.

The Holley and Carter are good pumps, but the thing I love about the Mallory is it's quietness. The Holley and Carter pumps are loud. As in "I can hear my pump ticking over my RacingBeat Exhaust at idle" loud. The Mallory is just as quiet as the stock pump.

One word of caution: You cannot mount aftermarket pumps in the stock mounting location. Most aftermarket pumps must stand upright (like an open pepsi can on a table) and not lay horizontal like the stock one.

It's a pretty easy install. Some fuel hose, some bolts with nuts, a drill, a new fuel pump and a new fuel pressure regulator. That's all you need.

Get the Mallory Comp 70, it rocks

i would get a holley blue pump with a fpr from holley regulate it to about 6 psi and if you later want a bigger carb or go turbo walla you are all set no need to spend an additional 120.00 on fuel delivery

 

everyone says holley blue when i ask to order it the say another name holley adventur comp blue in colr is that the one you are all talking about?

 

from yawpower.com:

Fuel Pump
The fuel pump needs to flow enough fuel that the pressure seen at the inlet to the carburetor does not drop below the preset pressure level at high rpm. This means that the pump must be big enough to overcome a slightly clogged fuel filter, or anything else that may cause a restriction in the line. Choosing a fuel pump is relatively straightforward. It simply needs to flow enough fuel to get the job done.

I have had the best luck with the Carter 7lb. pump. This pump is big enough to supply fuel for any 12A application, and has proven to be very reliable. It is half the price of the Holley, and at least twice as reliable.

The stock fuel pump is barely adequate for its intended purpose. Do not even consider running an aftermarket induction system with the stock pump, two of them wired in parallel, or any other combination. This goes for the Facet as well. A large rotary vane style pump is the only thing worth running, and as I said before, the Carter has proven to be the best. (It is also the least expensive!)

Fuel Pressure Regulator
The purpose of the fuel pressure regulator is to supply the proper pressure to the needle and seat valve. The stock system does not use a regulator, and as a result, the full throttle mixture changes as the pump wears, as the fuel filter becomes clogged with use, and as the rpm increases. In other words, the fuel pressure at the carburetor is only correct when the pump and filter are brand new, and consistently gets worse over time. I have seen such a wide variance in pressure and flow rate that even a bone stock RX-7 could benefit from an upgraded pump, and adjustable regulator.

My current preference is the Holley or Carter low pressure adjustable regulator. They are the same regulator, only the name is different. This regulator is inexpensive, and can be adjusted from one to four psi. A fuel pressure gauge will also be necessary. The Holley regulator has two outlets, and a gauge can be threaded into the second outlet, or mounted remotely. Extra diaphragms are available at a reasonable price.

The small dial type regulators made by Purolator and a few other companies restrict the fuel flow at high rpm, and should not be used. The Holley/Carter is only a few dollars more, and is capable of flowing any amount of fuel a rotary could ever need.

 

Racing beat said get a 10 psi fuel pump 20 gph because i may get the holley set up from them can I still use the holley blue with the holley carb from racing beat?

 

go for it but don't use a 10 psi fuel pump w/o a pressure regulator, or you will blow your carb off.

 

I know that can I use the red holley fuel pump with a stock carb and then down the road for a holley carb?

 

?

 

yes, with an FPR.

 

crad what is the difference between red and the blue?

 

Everything depends on your needs. RacingBeat recommends that because they work on a lot of highly modified setups.

The Comp70 is a 70gph pump at 6psi, plenty of fuel for stock and lightly modded 12a setups. If you plan to be heavily ported soon, go for a Comp110, which pushes more fuel, same pressure (6psi, 110gph).

I believe red = 97 gph & 7 psi , blue = 110 gph & 14 psi.
