I'm having trouble finding a complete kit with the FMU and the boost a pump, I tried jegs, superchargersonline and superchargers4less. The kit jegs had didn't have either one and the two later ones have the FMU but not the boost a pump, I don't want a tuner kit cause i'm gonna leave the engine stock.
thanks for any help
Get the kit with an FMU and order a GSS340 fuel pump seperately.
Yup, as far as I know nobody's kit includes the boost a pump.
Give Dave @ www.jdsperformance.com he can get every part you need. The kit will come in one box, the pump in the other. If you need injectors, MAF, ect.. he can take your complete order.

I would really perfer to run the stock in tank pump and just add an inline pump beacause other than the blower i'm leavin the motor stock.
Is the Walbro GSS 340 an intank pump?
yes it is in the tank. Dont run the stock pump. Its probably easier to change the intank pump than adding a inline. I changed mine last weekend... took about 1hr. total from the time i drove it in the shop and drove it out. Make sure you really low on fuel though.
Basic physics: Fuel flow (volume) goes down as pressure goes up -- basically (not exactly accurate), you double the pressure, you get 1/2 the flow. An FMU can spike your pressure up to 80 psi quite easily.
The Walbro 307 and 340 are both in-tank pumps, the 307 flows 255 lph up to 55 psi and the 340 flows 255 lph up to 80 psi. The 340 costs anywhere from $10 to $25 more than the 307, both are right around $90-$120.
www.racetronix.com sells pump kits with a nice wiring kit included. These pumps can draw up to 12 amps to push over 60 psi.
Intank pumps are easier to deal with than add on pumps if you ask me.
thanks you guys have been a big help
What all am i gonna need to run a bigger intank pump? AFPR and gauge, new sending unit that kind of thing
You could get away with an adjustable FRP and then buy a FI fuel pressure gauge that attached to the schraeder (sp?) valve if you don't want to drop the cash for an interior mount autometer gauge.
I too will attest that the in-tank is easier to install, just make sure that the gas tank is nearly empty when ya drop it. I also would recommend the Racetronix kit, a little more expensive at first but the slick harness makes up for it and if you decide you want/need the harness and relay later they want a pricey sum for just the harness.

As far as that goes if you promise the engine is gonna stay stock then just buy a used or new 190L pump as it will be more then enough.
I have a used 190lph Walbro fuel pump that i took out last weekend if you interested in it. I swapped it out for a 255 and it works fine. email me at jpbertrand@peoplepc.com if you interested in it. i'll let it go real cheap.
it will come with a brand new wiring harness and all instructions.
Buy from Dave @ JDs Performance. I bought a Novi (actually 2 Novi's), a MAF and some injectors all from him last month. EXCELLENT customer service.
what way is the best way to go FMU or bigger injectors and Maf, The car will see no track time at all that kind of stuff dosen't matter to me. The car is a show and cruise around car, I would just like the car to run better. I someday might throw the trick flow engine kit on it so i'm gonna go with walboro GSS 340 for my intank pump, So i won't have to do this again down the road.
One more question
Will my stock alternator beable to keep up with the new pump and everything
Agian thanks for all your help
