ive been running the 4cyl pump now for a while. it runs ok but maybe it could run better with the 8cyl pump.

what do you mean a 4cyl pump was the car converted to a v-8 from 4cyl and is car fuel injected??

yea sorry its an 88 4cyl conversion. its fuel injected w/ mass air conv.

As long as the fuel pressure is in the specified range and you have no drivability issues I wouldn't worry in my napa catalog it lists two different pump numbers for 4cyl and 8 cyl models but they both flow a max of 18 gallons per hr which translates to 68lph ...however to my knowledge they were 88 lph pumps in the 5.0
