s5 vs. s4 fuel pump...
 

any difference? does the s5 push more?

I doubt it, because injector sizes didnt change. Part #s are different though.

the s5 engine has 20 hp more stock, so im thinking the fp was a bit better to handle it. im switching to a s5 tank. i want 300 miles to the tank, and i figured id cheat. but i was just wondering
