1981 Trailfire fuel line route

Post by 1977Polaris »

What is the proper route for the fuel line on a 1981 Trailfire?
Here is a picture of our current restoration project. We have the blue fuel line routed through a out of the fuel pupm through a clip, underneath the steering column and motor mount plate, and up around to where it will connect to the carb. This keeps it away from the jack shaft and steering column. Is it correct? Does it matter?

I'm not so sure it really matters as long as it doesn't rub on something the will rub a hole in it ( Motor Plate etc. ) or have any crimps in it.. I think I would use one of those nice blue lines to operate the fuel pump from the engine impulse rather than that old green one, Unless you are really sure it's in excellent condition??
Also I'm not so sure you want that excess wiring harness wrapped around the intake like that, I believe it just lays in the right hand side of the belly pan where you can zip tie it to something??

X 2 On that one. I had one of the green ones crack because it was so brittle. Like Kenny said Polyfuel line works well for the impulse line.

We will replace the green tube. The electrical wires are just sitting there for now since the sled is mostly disassembled. We will lay the wires in the correct spot when we put it back together. Thanks for the comments guys.

You can actually see a couple of wear areas on the loom already.

Good Call Kenny. :clap:

Remember that this picture is taken with the sled half disassembled. The wires were run in the position you see above. We have repaired the wires and have put heat shrink tubing on the wire loom. It is all ready to lay back in its proper place and route through the J hooks in pan and hood. Thanks for the comments guys.
