Headers hitting fuel lines! Please Help

I just installed hedman headers on my 84' GMC 350/350. It has dual fuel tanks. When I installed the headers, I noticed that on of the primaries on the passenger side is touching the fuel line. It is a metal line. What should I do? Can I bend the line or could I put something in between the headers and the line to insulate?

Thanks in advance for any suggestions!

bending the line would be fine... maybe bend a new one completly so its away from the heat so you dont get vapor lock or something.

What would be a good way to bend the line now, without removing it or removing the headers? I dont want to have to reinstall those things, it took me like 2 1/2 hours.

I would cut into the existing line and add a foot or so more line. Then bend it well out of the way of the headers. The new line can be attached by using inverted flares. (The same way brake lines are installed.)

If I can bend the lines about 1/8 of an inch it will not contact the headers anymore. Would it be ok if the lines were just close to the header and not touching?

Any where near any heat source will cause the fuel to heat up and possibly vapor lock. When idling in traffic it can cause power loss and possible hesitation under heavy acceleration. I had a gas line lying on my heater hose in my Vette and it would cause the car to bog at the starting line when racing.

Syphon all the gas out of the tank(s) before cutting into it. Use a tubing cutter not a hack saw or cut off blade. Do it when motor is cold.

Thanks for the suggestions, I put about three layers of the Thermo Tec insulation between the header and the line, probably about 1/4 inch thick. Do you think that would be enough?

Having a gas line lying on a header, insulated or not, is dam scarey in my world. If the car doesn't explode, it's enough.

Fuel line..

Doc here ,

Here is what I usually do in cases where no clearance is possible..Might work for you..

I usually cut the line way forward of the header, and way behind..like a few feet or whatever it takes..Remove the steel line..

Get GOOD quality Fuel HOSE and good quality Clamps..and a length of steel tube slightly larger in diameter and slightly shorter than the hose..

Add the rear side of the hose to the line and route it to the outside of the frame...(preferably over the top of the frame not the bottom) Then slide your tubing over the hose and measure it to fit on the outside exposed side of the hose..remove it and cut it, reinstall and mount with steel adel clamps and tech screws and locks..

At the front, once again over the top of the frame, route the hose back to the front side of the fuel line and hook it up...your done!

You can use braided line in place of using lager steel tube, but I like the tube because it offers resistance to anything thrown up from the road..

Just another way, cheap and quick..

Doc

What I did on mine is to cut the fuel line right about where the collector is. I then ran regular 3/8" rubber fuel line from there to the fuel pump running it on the inside bottom of the frame and fastening it with clamps to keep it away from the header.
