Fuel Pressure Regulator

[CamaroAdam73]

Alright so i'm about to order a new fuel pump for my car, for good messure because i don't know how old the old one is, as far as i know it's from 88, so it's about time to go before i make a long drive on this car.

I just installed my new Edelbrock 750 Performer, And my question is, which fuel pump should i buy?

It's between theese two fuel pumps

Or

AND if i pickup the one from KMJENT, should i buy a fuel pressure regulator also?

* I'm leaning more towards buying the one from KMJENT, because if i do that then I'll have the money to pickup a brand new Aluminum HV water pump for my car too, I'm really strapped for cash right now so every penny helps lol!

I'm replacing the water pump and fuel pump before i leave, i'm going to be taking my car on an 850 mile drive to PA, So i'm making sure its in tip top running shape before hand.


And if anybody knows, what are the pros and cons of an electric fuel pump VS a mechanical?

Because i'm looking at this electrical pump also

A big con for a mechanical fuel pump is that it's mechanical. Reducing friction = more hp, but if this is a street/driver car then it would be much easier to go the mechanical fuel pump route. Also you have less to worry about with the mech. fuel pump, there's no wires or electric that will ever go out. But I'm no expert

The biggest plus with an electric fuel pump is priming and tuning, and could be worth it if your car is hard to start. You can send fuel to the carb before you crank the engine by just flicking your switch on your dash. This is a very good idea if you don't drive your car once or a couple times a week, in theory you could let it sit for months and charge battery/activate your electric fuel pump, and it'll start right up. You can also make adjustments to the carb and float bowls without turning the engine on, and electric pumps are mounted near the gas tank so bleeding your fuel lines is much easier (the biggest pluses)

I would look for one that flows 110 gph at a normal pressure, 6-8 psi. If you do go as much as 150 gph then a feul pressure reg. would be needed, but you can count that out by just looking at 110 gph pumps.

Another idea is to mount a free flow electric fuel pump inline, and just use it before you start the car up and switch it off.

Electric pumps are annoyingly loud. And to get the fuel to the pump the correct way you need a sump in your tank to gravity feed them. I would stick with a mechanical pump. The Edelbrock one is a good one. Depending on your power level you could probably get away with the other one or a stock replacement. You don't need a regulator with any of the pumps you listed.

Thanks for the advice guys, I'm going to go with the cheaper mechanical pump from KMJENT, The horse power loss is like what, 2-3 tops? Not a noticeable difference at all. And knowing that i Don't need a regulator because I'm going to stick with a 110-115 pump saves me an additional 30$
