Ok im hoping somone with the same setup will answer me.



ive got a gsl-se, ive ordered the holley 600cfm kit from racing beat, they dont sell a fuel pump for the application.



they reccomend the mallory 4070m fuel pump, so ive ordered everything right, sounds good so far.



WEEEELLLLLLL not so sure all is going well now.



racing beat says that i need a minimum of 6psi of delivery, well the mallory 4070m is listed as a maximum of 4psi, clearly not enough fuel, but on the summit racing site i ordered the fuel pump, its says, good for 4-100psi of delivery.



does anyone have any idea what the crap ive got going on?



im was told by racing beat that i dont need any other parts, i asked about a fuel pressure regulator, they said no, i dont need one.



ive got no experience with this sort of thing, is the pressure adjustable on the mallory?

4 to 100 PSI? that sounds weird to me ... are you sure you read the units right. it would make a little more sense for that to be a volume output than pressure - not a whole lot more sense though, just a little.



at any rate, if you've already ordered it and it's on the way to you, i'd say the best thing would be to just wait and see what it says when you get it. my guess is that is RB specified that pump, then you're okay to use it. you can always return it or exchange (or whatever Summit's policies permit) if it's not what you need.

the pump is correct, someone was just getting a little anxious.



the pump has an internal regulator that is factry set to 6psi. i dont know what the range of the pump is though
