Do you guys have any suggestions on electric fuel pumps? This is the one I am thinking of using:

Image
''Red'' Standard Pressure Pump
Ideal for ''street'' or performance water applications and is pre-set to approximately 7 psi. It will flow 67 gph and maintain a 5 psi line pressure. Free-flow capacity is 97 gph. This pump does not require a regulator. (Includes check valve and filter screen). Not for use with alcohol.
The Marine Red Standard Pressure Pump meets U.S. Coast Guard regulations

Should that pump be good or is it an overkill? And it is true that I will not need a regulator?

Sorry for all the questions but Im getting ready to order a bunch of parts and I just want to make sure I get the right stuff.

If you use that pump you will definatly need a regulator set to 3 PSI. Any higher pressure will just flood the carbs. Higher pressure actually lifts the needle of the seat and overfills the float bowl especially when off roading.
You can buy a pump set at 3psi.

I use, recommend and sell the 3193 version of these for Weber/Dellorto carbs:

Well, I am ready to get my fuel pump since the motor is finally done.
Am I correct to assume that I will not have to run a regulator with the pump that Gary suggested?

I run a Holley pump like the one in the pic you posted, but it is a blue one, it also comes with a regulator so you can set it anywhere from 1-15 psi. I bought a fuel pressue guage at a local racecar shop for $10 to put on the regulator. Works good for me.

That Holley Pump is a pretty big pump. The Facet/Mr. Gasket ones work well, but the CB Rotary works a little better. I would get the CB one. You can run them straight, without a regulator. IDF/IDA Carb's only use about 3-3.5 psi of fuel pressure. By running a 7 psi or 14 psi Holley Pump "deadended", and regulating it down to 3 psi it's fairly hard on the pump. If you do have one of the Holley Pumps, I would run a return line so the excess fuel pressure not needed at the regulator can recirculate. I know of a few people running the CB Pump on Drag Cars with dual IDF/IDA Carbs without running out of fuel. Unless you have a huge engine with huge carbs, the Holley Pumps are overkill IMO.

If you talked to Holley about the fuel system, then it must be all right to run the pumps without a return. The only engines I have seen that were large enough to use large pumps used Aeromotive Components with thier bypass regulator that had a return line. I guess the Holley pumps/regulators weren't designed to be used this way. I still find it hard to believe that running a pump that flows 70 gallons per hour at 9 psi, on an engine that probably uses less than 5 gallons per hour at 3.5 psi, is not hard on the pump.

I know that it sounds crazy, but that's what they said about them. I will be the first to know if something goes wrong. :lol:

Baddvw I run the holley BLACK pump preset at 14 psi and flows 120 gph. I stretched the relief spring to set the psi to 20. Had run the pump on my duster with twin turbos for a few years and now its on my rail. I use a standard holley reg. modified to reference boost. The pump leaks out the weep hole sometimes when it's cold. Holley makes a by-pass/return regulator that can be used with these pumps adjustable from 4.5-9psi Part #12-803bp.
