    I'm looking for some advice. My 3" exhaust comes too close to the vent lines exiting my gas tank. In the pic you can see the rubber hose comming from the vent laying right on my pipe. I tried to reposition the exhaust but still a no go. Right now I'm leaning towards pulling the tank cutting back the vents welding them closed and running a vented gas cap. The car is a 73, and the tank has 3 vents 2 on the r/s and 1 on the l/s. the Exh system is a Pypes Violator 3". I'm all ears for any advice on how to correct this problem in a different fasion. Thanks Guys Rob

    Dump the exhaust behind the axle? (or is that not an option)

    The exhaust is what you need to fix, you should be able to trim it somewhere to make it fit. Why did you put in a 3" exhaust in the first place?

    Looks like the pipe needs moved toward the front of the car, looks like you have plenty of clearance to the axle to accomplish that with no real problems.

    I would move the tailpipe forward by cutting a small piece off and possibly relocating the hanger. That with maybe the elbow picture above and possibly a small dimple in the pipe should easily get you to where you need to be

    May consider making a heat shield for it if possible. After you move it.

    Something isn't right with the way you have your exhaust put together. It shouldn't be near that close to your tank, and a tank is pretty hard to get in the wrong place.

    Try putting your tails in first, and work forward. Pypes stuff is pretty well engineered, but expect to do some cutting trimming somewhere, ususally between the muffler and headers.

    I agree the problem is with the exhaust. I bought a cheaper kit and it was no where near the lines like that.
