PROS & CONS BUYING AN ELECTRIC FUEL PUMP

[SCHOONER]

Hi Guys

Need advice,help,comments,directions, etc,etc.

Here's the deal. I have a '66, 289cid 'stang. I'm having the block bored-out as lest as possible. Bought a new T5 tranny.

I'm looking to have just a little bit more performance; not to race with or drag around the street (2 ol' 4 that stuff ) Just want to have a good running engine with less stress on it as possible.

Now, I'm confused at to what I should get as far a fuel pump is concerned.

QUESTION(S)

Do I buy an Electric Fuel Pump or stay with a standard one

I'm learning as I go along with all you guys helpin' me.
Just want a peppy little engine.

I'm in your hands guys.

THANKS TO ALL WHO HAVE HELPED ME IN THE PAST AND THOSE WHO ARE HELPIN' ME NOW.

GOD bless you all

this is really personal choice,there are pro and cons for both elec and mech. pumps. elec pumps make a lil noise before you startup and its easy to tell when they aint working, mech pumps are harder to change out if one goes out, but its tucked up by the engine out of the way and if the engine isnt runnin it aint pumpin gas, unlike the elec if you get a leak you could empty the tank and never know it. myself this is what ive run for years (see link) holley makes some good mech pumps and the good part is they are rebuildable you can just order a kit from holley when it goes bad and you goin again.. im sure some guys like the elec pumps and ive used them on the street before and on my race stuff but my street cars are mech now....my 2 cents

I personally prefer an electric fuel pump. They do make a little noise that might irritate some folks. I use a Holley (don't get a Mallory anything). I think you need an oil pressure cut off switch so that the fuel is automatically cut off when the engine is not running. Holley makes one for around $20. Another $100 or so for the pump itself.

An electric pump is eventually what my stang will end up with. With where you say you are going with your mustang, I am not sure an electric one would benefit you all that much. If you were going to go electric, the stock fuel line should be replaced too.

Hi Okiedragster

I read what you said about mechanical fuel pumps and I think that one of 'em will suit my needs.

I'm building a moderate performance engine will help from great guys like yourself on this board, and I don't want to get too crazy with having a HIGH PERFORMANCE ENGINE.

The only thing that I don't know (plus,lots of other stuff about engines) is:

I picked 3 possible mechanical holly fuel pumps. Here's what confusing me

one pumps: 80gph, other110gph and lastly: 130gph

G(is for GAS)? P(is for PER)? H(is for HOUR)?

THAT COULDN'T MEAN: GAS BURNED PER HOUR i.e. 80gph I would use-up 80gals.of GAS!!! NO, THAT JUST CAN'T BE RIGHT.
See I told you I was lost in the woods (PLEASE EXPLAIN)

Pressures are: 71/2 on the 80gph
Pressures are: 6.5 to 8 on the 110gph
Pressures are: 7.5 to 9 on the 130gph

Can you or you other guys out there please explain these numbers I'm lost in the woods again . . . lol

I'm looking for something a little above average for my '66 convert.
Can you give me some suggestions please as to which one of these pumps would best fit my applications

THANK FOR YOU PATIENTS.
GOD BLESS

honestly i think the 80 would work fine for ya. if ya get one with a higher pump pressure you may have to get a fuel pressure regulator and a gauge and set it on about 7 or 8 pounds,because you dont need to put any more than 8 pounds of pressure on your carb's needle and seat. and the way they rate their pumps is at a free flow rate of (gallons per hour) gph.i have a 80 on my cleveland motor and its got a few goodies in it and it works fine, if you have any more questions let me know or post here...

[Rev]

Those gallons/hour ratings are for what's called "free flow". That is the maximum that the pump would put out if you were just squirting into a container. The carb has needle and seat valves in the float bowl that regulate how much gas is allowed in there to keep the proper gas level in the float bowl. Believe me it won't be 80 gal/hr. From what you are saying that you want from your engine, I think almost any fuel pump will be sufficient for your needs. Even a generic auto supply house mechanical pump would probably be OK as long as it keeps 5-7 psi to the carb.
