anyone got any good ideas about wrapping some rubber fuel hose i have running down the firewall? or will it be ok?
they make flame retardent split loom i could wrap them in for a decent price, just not sure if that would be alright.

the lines are not touching anything but the firewall as well.
 
You only need to really worry about the fuel lines where they come close to the exhaust. Just being under the hood and especially near the firewall you shouldn't have any problems.
 
Run steel braiding, that is what I did. got a kit from summit. works.

But I did have to wrap the steel braided with some tube to keep it from digging into my rad. hoses, lol.

i plan on doing that in the future but i am too broke right now to buy the kit. Ill do it in a couple weeks probably.
 
When I bought my 91 burb and was doing the 383 swap I found one of the factory braided fuel lines was almost wore thru. So when I replaced them I used some 5/8 inch heater hose and covered them from the back of the manifold to where they meet the frame so I won't have any engine fires.

Same here, the braided fuel supply line had rubbed the body so long it work a hole through the floorpan right in the corner of the passenger footwell. The floor mat had blocked the hole enough that it wasn't noticeable but the first time I turned the key after pulling up the mat the priming of the pump was enough to spray a stream of fuel into the cab.
 
when we had the fuel lines on the frame near the headers on a friends early bronco we bent some conduit to match the frame shape and ran the fuel line in it.it protects it from heat and any other damage.
 
I kind of went overkill. I wrapped each metal line with strips of the adhesive backed barrier. Then, I cut pieces of aluminum to fit into the frame rail, attached the same adhesive backed barrier to each piece of aluminum, and placed them over the top of the fuel lines in the frame rail. After that, I used their header wrap on the exhaust pipe where it ran along the frame rail to further keep the heat away. I was having problems with the gas boiling in the metal lines due to the proximity of the exhaust pipes and the gas lines. I found out later the carb was out of adjustment and I was running a little hot which didn't help. Now, no problems at all.
