I will be needing a new fuel pump really soon and was wondering if anyone has switched to an in tank Walbro 340 (255l/hr high pressure pump) - or any other in tank pump for that matter? How was the install? Did you have to splice any wires?

 

someone around here did an intank, seems like it was jojo.

i did a aux inline, it was easy to install, quiet and so for has handled my needs. i think it can get me to mid 11's or so with my heavy rig. when i was running prety rich i could get the presure to drop but now with my af ratio dialed in(11-11.5/1) it is keeping the presure up. on a non blown set up this inline would take you even farther since you wouln't need to be as rich as me.

 

parish, what inline are you running? need info on fuel systems for my upcoming 6.0 swap.

 

i am using that same walbro 340 high presure pump, just an inline version, seems like the number is gs340m, got it from speed inc.
