Stalling cat -Spin on Racor + other question

[randydupree]

one thing about the racor is its outside the coach,you don't have to worry about
fuel smell in your carpets as much.i've found that the racor last at least twice
as long as my secondary filter,and when i have had fuel problems i only changed
the racor,maybe 5 to 1..its kinda like having a spare tire i guess.do you really
need it? i like having both..randydupree93wb

Bill,
If he had an air leak, I'd have said to bypass it. He
apparently has a fuel system plugged with crud and I just
can't see moving the problem forward. Might as well deal
with it in the back.
I can't help but constantly analyze. I'm a mechanic and I
just can't stop. It's like asking a cat to not chase a mouse. LOL
I've learned a lot about mine and may eventually come around
to your way of thinking. ;o)
