Been searching and found several different ways of routing a return fuel system. I would like to build my own and want to make sure it is done rite. What I think is from pump to filter,from filter to y-block,from y-block to fuel rails, from fuel rails to regulator,then return to pump. Will this work or am I way off.
Sounds like the correct routing. IMO makes more sense to buy one of the modified hats that already have AN provisions for the feed/return vs hacking up stock.
The way I have most often seen this routed on s197s at least is
Pump to filter, in one rail to second rail out of rail to regulator and back to pump.
I have heard of others doing it differently and would check with your tuner if they have a preference

Impossible to beat value n quality of Lethal's Budget Return system, stuff just plain works n is hassle free. Some of the other kits out there are built by peeps clearly confused between the needs of a Top Fueler and a real street car.

I already have a lethal performance tipple pump hat using two 340 pumps with 1 pump port capped. So time to use that return side. Thanks for the info.
If going from returnless to return, be sure you use correct pumps.
Thanks for the help will update with results.
