    i have a 1988 chevy, i'm swaping the t-case to a np205 and changing the exhaust to go out the driver side instead of the passangers. here's the problem. the fuel lines run down the frame on the drivers side and the fuel filter will be less than a foot away from the catylitic converter. so i was thinking of doing one heat shield on the frame rail and then another a few inches away and not connected, but will this work?

    Any time you can create an air space (especially moving air) your doing better since only radiant heat can travel (or close enough). My guess is the double shield would work well enough...

    thanks, i wanted confirmation that it should work. the tbi is bad enough with out having vapor lock due to heat too close to the fuel line.
