ok well i was looking on ebay for a fuel pump because mine makes this really really really loud buzzing sounds and i wanted to know if it to much to buy say a 5.0 fuel pump for my 4 cyliner

HAUS

yes im pretty sure they use the same 88lph fuel pumps. but im not sure if you can use a 110, 155, 190 or 255 for the 4 cyl. but dont quote me on it. any one else have their opinions.

DaGGer

well its like 30 dollars for a 110 on ebay and like 90 at advanced auto parts...so i would rather buy that one instead

HAUS

I understand you want to save money but find out first if you can use a 110 lph in a 2.3 L. No sense buying it if its not going to work or is gonna make your car run like ****. 110 might be too much fuel for a 4 cyl. PM roundman. He probally knows for sure.

the fuel pump for the 4 and 8 are the same..yes you can use a 110 lph pump....a 225 would cause problems in your 4 banger and even in near stock 5.0's....

ok thanks

k a question on the fuel pump issue.. IS ther a performance gain if you combo a fuel pump with some injectors, and a MAF&TB upgrade?

yeah. if u put some AFR's and a street/strip cam with other little goodies, u should upgrade your fuel delivery for the A/F ratio's concern. And with the head and cam upgrade it will benefit greatly with a larger MAF and TB with matching injector sizes along with a larger fuel pump. The fuel injectors and pump dont increase hp, but accomadate to the hp makers. They're nessesary for aggressive part add-ons.
