Default Adjustable FPR w/ stock lines??

I'm currently installing a Racetronix dual Walbro 340 setup which is a bit overkill for what I need right now but I don't want to do this twice once I step up to bigger cubes + a DP kit. I know some of you are still using the stock intank FPR, but it seems to me that even 1 Walbro pump is almost too much for the stock unit.

I saw a post using search where 35th SS (I believe) had a nice bolt in unit from Xtreme motorsports that just replaced the T block in the rear. I contacted them about this FPR but unfortunately they are no longer selling it and it's out of production. Which is a damn shame because it looked like a nice piece.

So anyway, does ANYONE know where or how I can mount an aftermarket FPR without completely replacing the lines? I'd like to use the stock lines for now if that's possible. Any ideas?

Hmmm. Guess nobody has done this before...... anyone just replace a small section of line just so that they could install a FPR?

No you would need to replace the entire feed line and use the stock feed line for a return. We have a complete kit with our fuel rails to make this an easy upgrade.

you can replace the soft plastic tubing going over the axle and into the tank with regular fuel injection hose. anywhere you want within that length of hose you can splice in any fuel pressure regulator you want.. just remember to take the stock regulator out of the tank..

Thanks dude, that's the info. I was looking for..... How would you connect the fuel injection hose to the plastic sending unit on the tank though? Or are you not talking about the hose that attaches to the sending unit. The stock regulator is a part of the sending unit intank correct?

If you could post up some pics of this when you are done that would be awesome! I'm not sure which regulator to use.
