[sm=helpout.gif]My 88 GT needs a new fuel pump ... The motor's basically a stock 5.0 except for a Mass Air Conversion Kit , K&N filter & a pair of Flowmasters ... Can I use a 155 lph pump or should stick with 110 lph ? ...

Thanks in advance ...

110, that is still more than the stock 88lph

 

For a few more bucks you can get a 255lph pump. Walbro makes a GSS307 255lph standard pump and a GSS340 high pressure pump for forced induction. You kow you're eventually going to add more power so you're better off doing it once. Trust me I went from a 110 to a 190 to a 255. If I knew then what I know now I would have done it once.

 

I'll sell you a stock functional one for $20, got two laying around...
