heat reflective tube stuff
blakep82 - 2/2/11 at 12:54 AM

on my car i need to run the exhaust through the tunnel, with the fuel line. they go on opposite sides on the tunnel so thats fine, and i don't imagine heat will be a huge problem, the exhaust will be wrapped in exhaust wrap through the whole tunnel, but i'd also like to put the fuel line through something like this from rally design

where's good to get it from? needs to be super cheap

The tunnel will get very hot, even with heat wrap.
I would run the fuel pipe on top of the tunnel with a false tunnel top.
I would also line the tunnel with heat mat ( expensive) builders expended foam silver backed floor insulation(very thick) or 2 layers of silversided bubble wrap, stuff you can get on a roll for £10 in B&Q

The exhaust on my Fury passed through the side pod as most of them do. Even with judicious use of strategic ventilation it still got incredible hot to the extent that when using the car in winter, the heat soak from the exhaust would still burn my leg when rested against the chassis.

My advice is to be VERY careful with where you run the fuel line and the heat break that you build in.

Is this LCB speak for, "I've already committed to this and have convinced myself it will be fine".

I'd think about copper fuel pipe as that will handle temps above 130degC and local hot spots (i.e. where the heatwrap moves, or you have an exhaust leak) will be less of a problem because of conduction.

Nimbus G2 and Nimbus light seem to be good products for heat shielding and will find a place in my turbo installation. I don't know about sleeving.

its speak for, theres no where else for them to go! they both have to go in the tunnel

copper might be a good call, or plastic inside heat reflective tube, inside a metal proctive tube?
theres a guy in town who owns all sorts of race cars, he also runs a van hire place, i'm going to have him do it, but i'd like to find out where to get all the stuff i need first
