ZR8ED Posted August 6, 2001 Share Posted August 6, 2001 Hi folks I was looking up fuel pumps at the local speed shop, and the dude at the counter was only able to find one aftermarket pump for FI cars that was external.. ie inline rated @ 125 psi???? holy crap!! can you even use this with a FI Z? I checked out Summit online...kinda confusing, and very little on specs..ie flow and psi ratings... what are you guys using? Thanks, Scott.

BLKMGK Posted August 7, 2001 Share Posted August 7, 2001 Drat - lost my reply.. Aeromotive, Mallory, Paxton, Walbro, Accel, Vortech - all make EFI pumps. The E150 Van pump talked about awhile ago actually sounded good to me (OEM) but I'm not sure of the rating. Mallory makes some good ones IMO. Check th eMustang mags for PLENTY of fuel pumps - some inline some not. Just understand that BIG pumps are VERY loud and can brun out quickly if designed for race use and put on the street. (Walbro, Aeromotive, possibly the Paxton (I've got one!)). Here's some to consider... http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=6285&prmenbr=76&path=76%202317%202339%202341 http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=5924&prmenbr=76&path=76%202317%202339%202341 http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=27585&prmenbr=76&path=76%202317%202339%202341 (Holley) http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=26182&prmenbr=76&path=76%202317%202339%202341 (Comp110FI) http://www.jegs.com/cgi-bin/ncommerce3/ProductDisplay?prrfnbr=6203&prmenbr=76&path=76%202317%202339%202341 (I've got this one - LOUD!)

Lone Star 1 Posted August 7, 2001 Share Posted August 7, 2001 Hey Scott The fuel pump on for my LS1 is rated at 125 PSI also so I had to install a pressure regulator to keep the pressure at 52 PSI which is what GM recomends for the LS1.

BLKMGK Posted August 7, 2001 Share Posted August 7, 2001 Heh, I guess if they rate them at high PSI it'll flow more down low? At least it won't croak if you run a blower and one of those damned FMUs that cap off the return. Silly Paxton unit killed my stock Ford fuel pump in less than a week (ahem). Talk about spiking the fuel pressure! Quote Link to comment Share on other sites More sharing options...
