Return fuel system

[maxwell6]

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.
