My exhaust manifold has a crack in it and has cause the nylon fuel return line to melt and spring a leak. This happened on a trip towing a tent trailer through desert heat. The motor was working pretty hard and when we stopped I noticed a fuel smell. There was a puddle of gas collecting under the Jeep. Needless to say I grabbed the fire extinguisher and shut down the Jeep. It seems that when I let the Jeep sit at an idle, the nylon line heated up from the escaping exhaust gases and the now pressurized return fuel line sprung a pinhole leak.
I replaced the fuel line but still have the cracked manifold. It’s just a matter of time before the right conditions occur and it will happen again. Ultimately I either have to replace or fix the header.
As a temp fix I was thinking of wrapping the exhaust header with the exhaust tape like they have at Summit Racing. Anyone foresee a problem with this? Like I said this is just temporary until I can deal with the header.
