I plan on spraying a 100 shot this spring and have a stock fuel pump with 24#svo as of know. Anyone use either fuel pump if so how do you like it. I don't want to put a intank one in if i don't have to.

------------------

 

I run a GM Grand National in-tank pump and a T-Rex external. Don't have any pressure problems with this setup with 6 psig boost and a 50 shot of nitrous OR without the supercharger and a 90 shot.

I was using a stock pumpin tank + the SX pump inline. I had plenty of volume + more pressure capabillity than I would ever need. Until the magnets came unglued inside the SX pump. Now I'm using a Holley (Walbro) 255 ltr/hr in tank + Accels (bosch) big inline.
