Whipple with 43lb injectors
#12
If i go with a external walbro gsl392 which is a 255lph pump, i think this will be the easiest to install. Is this the right pump for this upgrade or has anyone used a different external pump. Any help would be great

Do i need to get a new fuel pressure regulator by adding this 2nd pump? Is the walbro 255lph inline fuel pump a good pick for this mod? Or should i install an in tank fuel pump. Is there any that are a direct fit. Thanks alot guys im lost when it comes to fuel pump like i said. I want to make sure that i get everything for this upgrade.

I too am in the same boat. I got a walbro 255lph made for typhoon's/syclone's but am not sure what all will have to be done to modify it correctly. Or, will an inline be better? I have a whipple w/ 6lbs. and I'm installing a new PCM and 43lb injectors.

I talked to allen at nelson and he the man that sold me the injectors. He said put them on and put a gauge on it and see what your fuel pressure is. If it is at or above 55psi at WOT you will be fine.
