Hello I have a 06 lq4 with a 2001 fuel rail that has a return line and regulator on the fuel rail it's going into my 38 olds business coupe I have a 3/8 line ran for fuel .


My question is I have no return line from the tank to the front of the car
Can I run a corvette fuel filter close to my tank and plug the return on the fuel rail ?
Not to long down the road I'm going to install a cam and ls3 heads and intake and ls 7 injectors .
Thank you kelly

Yes, you can run a vette regulator, but you'll need to buy an actual AN cap for the rail instead of using a vacuum cap and hose clamp. You'll still need the fittings that lets you return from the regulator to the tank.

It would be cheaper to just buy 3 fittings and a section of push-lok hose and return to the tank from the rail.

The vette regulator with fittings runs $60 plus shipping from Speedway. 20 feet of pushlok hose and 2 hose ends is $50 shipped. In the long run, it actually ends up being cheaper to run a full length return.

The stock rail mounted truck regulator also does a better job at actually being a regulator than the vette regulator does. It is vacuum referenced (and boost referenced) and can handle more flow before causing problems. A single Walbro 400 pump is too much for a vette regulator, whereas the stock truck regulator has been pushed to almost 1000 flywheel HP.
