Don't know what a fuel cooler rail is. I didn't do all that testing because
I didn't have VL. It came big time down here in 90 plus temperatures as
soon as corn gas arrived. I really don't know how you would cool the fuel
in these cars without the return line other than the way Mercedes does
it, they use Freon from the air conditioner. G.M.
