    Thanks for the info.  I currently have a 255 walbro in the tank.  Have that feed the surge tank?

    Or just incorporate this:  http://store.034motorsport.com/fully-enclosed-fp34-044-fuel-surge-tank.html

      Thats EXACTLY what I think you should do. I really like the product you found there! That will make for a super clean, High power setup.

          Well from after the surge tank, I would go to a 8an to the fuel rail, and then on the return side of the fuel rail, have a 6an line coming to your FPR, and then from the FPR, 6an line back to the surge tank. The surge tank probably also has a return to the stock tank.

            Also, You would need to convert the stock feed line to 6an somewhere, whether it be at the stock tank or just before the surge doesn't matter.

              Why would I need to do this?

              I have to do this fuel thing sooner than later.  The fuel pump took a dump I think.

                For the return from the surge tank. Hey will you be at spring green? I would love to shoot some ideas about surge tank placement/size. I would love to have some of my work on your car sir :)

                  I will not be able to make it. 

                  Back to the pumps:

                  Here is the pump I'm going to get.  I might run 2 of these.

                  http://store.034moto...surge-tank.html which would run in tandem but as an external pump.  These would both be running all the time.

                  This would be easier and should work just fine.

                    im not a fan of dual pumps running in parallel like you would with the hobbs switch, 

                    Id rather not run dual pumps in series, but thats an easy way to go about it

                    If it were me, I would have 1 very high flow pump and just let your fuel pressure regulator deal with it.

                      Yea If going in tank route definitely just do the simple way and just get a damn good in tank pump. One and done. How much power do you even plan on making and what fuel?

                        Pat Kummrow said it's getting fuel and spark. It might be an ecu issue. #sketch

                            ...For squirts,  or some sort of OBD-2 tuning system. 

                            You have quite a bit of untapped potential
