*Update-have had two of these pumps die on me now in less than 2-3 tanks of gas.*
*Read to bottom of thread for updates*
I've been trying to figure out which fuel pump to use when I swap in the 3.1 TGP motor.
I have a fuel pump on lifetime warranty from a truck like 10 years ago (before I went to Walbro's).
I pulled down the truck pump and the fiero 2.8 pump,here's what I found-the pics and application info speak for themselves.
Stock fiero part number E3240 (1988 fiero GT 2.8 Auto)
E3240 specs
Retail price---$73.99
Fitting size---5/16"
Fitting type---Inlet,filter/Outlet,hose connection
Gallons per hour--- 40 (151 liters)
Pressure rating---65-95psi
Warranty---1yr
E3270 specs
Retail price---$76.99
Fitting size---5/16"
Fitting type---Inlet,filter/Outlet,hose connection
Gallons per hour---50-60 (189-227 liters)
Pressure rating---80-90psi
Warranty---1yr
Part number E3270 is factory replacement pump for a 1997 chevy C1500 2wd 5.7.
Don't go any newer,or look up an SUV. I didn't check all app's but in 97 starting with the 4dr tahoe/yukon's they went to a factory module at $320+ (has exact same pump in it,just in a sending unit/module that your not supposed to disassemble-but you can)
Did a quick cross check of the vehicles I know have high fueling capacities.
The 97ish trucks of course are 350 sequential fuel injected vortec engine's.
It is also the stock replacement fuel pump for the 454 equipped truck,and just to make sure I checked a 91 GMC syclone 4.3 turbo and yep it's the same pump.
So basically,if it can fuel those your not going to have an issue with a turbo/SC 4.3 or smaller engine running out of fuel unless your running some massive boost,N20 etc..
It specs a little lower than the 255 *race* units but can be found at any parts store in the above applications. Don't mind the pressure rating,the SFI's ramp up to 65psi+ but only run about 45psi generally.
And the syclone is TBI right? so it can run low pressure also no issues.
I will pick one up in the morning (need to bring a core in that i've got laying around for the warranty) and install it when I get a day to do everything else i'm stacking up (inner/outer tie rods,rack bushing,shocks,pads,caliper rebuild,brake lines,end links/mounts etc..)
I see no possible issue with install other than maybe wiring the plug. I know they are both the same but most pumps nowadays come with a plug to be wired in anyway so your doing it regardless i'm betting.
Easier on application crossover that way I guess.
I'll take pics and update this thread with the install data.
I hope this info helps somebody.
As soon as I get ahold of an 88 front/rear bearing i'll use my bored time to find a hub that will swap in easily.
