the factory sender hole, did you just use it for a return line? Why does everybody use the vette filter? What about a regulator? Did you guys run larger hard lines (3/8)?
Joe, the factory hole is used for the sending unit for your gas gauge only. The vette filter has a feed and a return line built in so you do not have to run the return up to the motor ( the hemi's do not use a return) it's self regulating. As for the lines, I'm using 3/8" plastic lines with the push on fittings.
