I have a return system with an lines and a regulator. I put my flex sensor on my return line under the hood right after the regulator.

I have not installed but bought the one below. Its just like FFDP but comes with connector and compression fittings. I had to buy two other fittings AT165106ERL (earls fitttings from summit) for the stock fuel line to screw into each other. I will probably put mine under the cab somewhere since a LSA will be going on mine and space is limited.

@The_W Just put it next to the stock filter.

I agree, thats where I saw some guy on youtube do it. Only plus I see on doing it under hood is your wiring is easier and shorter.

Is this an older truck back when they had fuel filters?

Every GM vehicle I've owned 2009 or newer didn't have fuel filters.

Correct, after 02 they moved it to inside the pump.
