Technical Fuel line clearance

I’m running my exhaust out the p***enger side in front of the rear wheel. In doing so the exhaust will p*** under the fuel line with a half inch or a little more clearance. I’m planing on adding a SS heat shield about 1/4” above the exhaust pipes and 1/4” below the fuel line. Will this be enough clearance to keep my fuel line relatively cool?

Fuel line is cheap and easily adjustable. I’d suggest keeping it well away by rerouting.

 

I don't know how the fuel line will take it, but I would not have the exhaust exit there. I'd go to the trouble of welding together some U bends to make it go out the back of the car.

maybe I'm just getting old.

 

that’s my plan after I get up and running I’ll take to an exhaust shop, getting it out the back is going to be a project.
Thanks

Every situation is different. What you are proposing will probably work. But you'll have to try it to find out. Just remember, driving on a 70* day is not the same as driving on a 105* day.
If Plan A doesn't work, go to Plan B.

 

if it's temporary, you probably don't need to sweat it too much.

 

Temp I wouldn't worry. Long term, I'd consider a forward facing scoop on the shield, just dip the forward end down some so forward travel will cause airflow over the fuel lines and floor. It won't help in stop n go traffic on a hot day, but if it develops issues, you know where the problem is and will have to take further steps.
Looks like 2 lines. Feed and return? Also looks pretty darn small.

 

Yep 2 lines 5/16” supply, 3/16”return. 5/16” supply should be enough for 250 to 300 hp shouldn’t it. The new sending unit/ pickup line is 3/8” but I reduced as I have 5/16 line. The donor car line was 5/16 also.

I've driven probably 200K with exhaust in front of the rear wheel and will say that it is best at two things. Giving you a ******** headache on a road trip if you don't have quiet mufflers and getting the rear wheel dirty.

As far as vapor lock goes, either it does or doesn't. With air space and the heat shield you have planned and maybe some heat shield wrap on the line you shouldn't have an issue . I put a length of that on the fuel line on my 75 Chevy C30 when I had a vapore lock issue.

 

I use an insulated high temp sleeve in any areas where I'm remotely concerned about heat on fuel and brake lines.
