You cant go too big with a fuel system that has a return line. I went with a 255 LPH and was happy.

What Brand Should I Go With???????and Will I Have A Problem With My Car Being Speed Density???

Re: fuel pump ???????
 

Walbro is a trusted name and you can get them on ebay for about $100 shipped. Also, speed density doesn't matter. That is the pump I have in my 93 Cobra and it works great, and leaves room for mods.

hey if u have mass air i would clean the sensor,oil from the k&n filters get them dirty and cause bog at wot but wont usally cause a starting problem..i had that problem last year ..you can get the maf cleaner at part stores but make sure you get the maf cleaner dont let any one tell you to use carb cleaner as carb cleaner will eat the wax off the resistor.u will notice a extra mile or 2 to the gallon neways.......yea walbro is the way to go ..good luck let us know how u make out

Re: fuel pump ???????
 

You need an adjustable fuel pressure regulator w/ guage, this will help determine what your fp is doing under load.

Goodyear1984, he said it was speed density in his post, also i've never seen "maf cleaner", i used rubbing alcohol, or electrical contact cleaner in the past, worked fine.

Re: fuel pump ???????
 

they sell it at auto parts stores like adavanced..i have it at work.electric contact cleaner would work to just dont use any carb cleaner
