Truck is a 2002 with a return fuel system. Has a sidemount Whipple and 60# injectors. Putting a A340 pump in the tank to eliminate the current frame mounted boost pump.

My question is, have the stock FPR's been working properly with the A340 pumps, or will an aftermarket FPR be necessary? Just curious if it can handle the additional flow(I'd think it could...)

 

You need a boost referenced FPR as im sure you know bud,

I wouldnt try it without one , not worth it to save 200 $.

 

Stock pressure regulator is boost referenced. I'm still running the stocker on my own truck, but I have a Delco fuel pump in the tank, with the Maggie pump on the frame rail.

 

Trying to determine if the stock regulator can handle the A340.

 

Yep, handles it just fine I've got an AM340 with a hot wire kit and never an issue.

 

Hmmm cool to know, did you have to mod it to adjust it Roger/ Kyle ??

Wasnt sure as i use a NNBS fuel rail.

 

Tim, It should work in your tank.

 

Nope, not a bit. FYI, the returnless uses the same regulator only its mounted in the fuel tank instead of on the rail.

 

I have the same set up as Kyle and although it doesn't have much runtime, it's been doing just fine.

 

I am running a bosch 044 pump on the oem FPR, have no FP issues. So i would say yah it will work
