Overkill on fuel system?

[andrewT]

Ok, so I've read and read and read and I'm still on the fence

72 Lemans, 488, 310cfm Alum D-Ports, 2"header, cam is 270 dur close to 700 lift, 11.3:1 CR, Torker 2 port matched, carb will probably end up being a Dominator. I have no clue what the car will run..hoping for a 10 second pass?

Will be mainly a street car so continuous duty pumps are a must. Sumping my stock tank. Would like to do something inexpensive like a Holley Black with -8 Lines but am worried it won't be enough...only thing is, next step up would be something like a Magnafuel Quickstar 275, -10 lines, etc and then the price of the magnafuel regulator and filters, etc compared to the Holley stuff is way more.

What can I get by with here? I have no problem buying the Magnafuel stuff if overbuilding is the way to go; but I read about 50/50 guys saying GO overkill on your fuel system and other guys saying NO NEED to go overkill on your fuel system.

Your 50/50 reasoning is correct!;) I used to run a Mallory 140 with their regulator and filter on my car previously with sumped gas tank, 1/2" aluminum line and I think dual #8AN lines from the regulator to the carb. The car ran 10.70's on average and never had any fuel issues. That pump is now 13 years old and still working perfectly on my wifes car.
When I completely redid my car last summer, including a new motor, I elected to go with the Magnafuel 500 setup because I don't like doing things twice plus I know that I'll never have an issue with fuel delivery for whatever I may plan to do with the car in the future plus the cost difference between the 300 was minimal in my eyes. Overkill is okay, better to be over than under and have to start all over again.

Holley Black on my car, dead headed, drive 30 miles to track and race it, no issues AT mid 10's!

Plan ahead for how much quicker you may wish to go. I ran a deadhead Mallory 140 for 19 years on 2 different cars (although it sat on a shelf for 6 yrs between the 2) on both gas and E85 going as fast as 10.12 on the last one using 1/2 inch hard line and -6's after regulator. I did have to rebuild the regulator once. If you want a return system, I like the Magnafuel 500. Either should work well on your setup.

Can't argue with Darby's results either.

I up graded from a Holley black to the Holley HP150 years ago. No issues with the pump.

[Rob B]

I think what you find is the simplicity that some guys have in their set-ups and what kind of performance they are putting out.:thumbup:

[andrewT]

so I guess the 150 gph Holleys will work just fine?

I'm torn...I mean if I want to push more power in the future I don't want to have to do the whole thing again, but damn is the magnafuel stuff pricy!

[Scott Stoneburg]

I like the 150. My brother has one on his car too. No problems and our cars are driven on the street too.

[Mike Davis]

My vote would be for the Magnafuel 300 pump and filter combo with matching regulator.

I was in your situation years ago;I ended up going with a Magnafuel Prostar 500.This way,I`ll never have to replace it.Maybe rebuild,but thats it.

I had 10 years of street/strip use with this pump,and never had a problem.

Electric pumps do a great job of pushing fuel, not so great a job of sucking fuel. Keep filters after the pump and only a strainer between the pump and the tank. Amazing how well a system will work if set up correctly. Aeromotive has some great tech stuff on their site.

Thank you for all the replies everyone. The opinions are appreciated!

Andrew, I have something that will work for you.
