I've got a hpfp95 fuel pump. And at idle it's around 16-17, at WOT it's about 12-13. I have the 3/8 line. If I upgraded to 1/2 would this help me get more fp at wot? I'd like to keep it at 16 all the way throughout. Or is the only way to do this, to get the 150 fass? thanks

That's easy...
Vulcan Big Line

This is with the Vulcan Big Line kit and the stock Cater Lift Pump and a stock fuel system with banjo bolts and 6mm steel lines. My pressures at the bottom...:thud:

Thanks that help's a lot. I'm sure if I get the big line kit now, my pressure shouldn't drop at all. Moparman what was your pressure at wot before you put the comp on there? Did it drop any after you added the edge?

Both of those numbers are before the Edge Comp... Afterwards it dropped another 2-3 PSI easy (Vulcan Big Line Numbers).

But I still would suggest you do a AirDog 150 or similar...
