i was bored and got to looking at my motor last night and realized that i have a return-less fuel rail. not that i am going to change it out or anything, just curious.
my question is, what are the pro's and con's of ones with and without a return line.
Some say with a return style system you have cooler fuel in the rail. Some think that it also flushed crap from the rail back to the fuel tank. Not sure on the second one but the first sounds logical.
The second is not what I have seen. A more logical explanation of a downfall of returnless, as I have 1st hand experience, is as follows. You have no inline fuel filter AND no return line. The stuff goes to the injector inlet screens and stays.
so fuel filter on frame = return style?
