ZR-1 Fuel Pump
Has any other C4 owners upgraded to the 1990-1995 ZR-1 Daul in Tank Fuel Pump Assembly as an Upgrade or replacement to thier Single fuel pump for their own Non- ZR-1 corvette ?
The Walbro 190L &255L & Racetronix Fuel Pumps are an Option, But researching on old posts, the Walbro Pumps can be noisy and have a pretty spotty reliablity record.
Weldon Fuel Pumps are the best money can Buy. What my Freind uses with his 8-second Vortech Blower Head Renegade Ford Mustang.
But the high cost for then are hard to justify for car in this REAL CRAP Obl@m* RUN ECONOMY.
What sort of tips do You other C4 owners have using a ZR-1 Fuel pump in my 1987 Vert ? Stock fuel Pump is having a difficult time keeping up at WOT with mods I have recently made.
ZR-1 Fuel Pumps new can be had for a decent price researching.

I considered this a few years ago. The 2 things that stopped me were cost, and not knowing for sure if it would physically fit in the 87 tank. Part numvers are different for the gas tanks used in ZR1's and my 87, so I thought the baffles may interfere.
I spent many hours in the parts catalog, and wound up using a pump for a lumina. The flow rates were equal too, or greater than the Buick Grand National pump, if I recall correctly. It supports my high 10 second runs perfectly.
