I have heard the pump fuel will be getting even worse for our carbureted muscle cars.
In these parts, ONE of the problems lies in the fact that you can't trust what the pump says...
Random testing has shown ethanol concentrations to be as high as 35%...
Sta-Bil, and a good shot of 110 has worked well...
So far...

The fuel line is not near the header as right below where you see the fuel line on the pass side fenderwell is where it comes thru the inner fenderwell as it runs up by the rocker panel and I drilled a hole for it to come thru the inner fenderwell. It does not run up along side the header tubes. I put it like that to keep it away from the headers. My buddies 65 does the same thing but his fuel line is closer to his headers I believe. It did it last year without the heat shield but I had the phenolic spacer on it then. So basically the shield made no difference. Ron

I kept the line outside by the rocker until it comes thru the fenderwell. I really did not want to run the fuel line lower along the frame by the control arms as thats why I bring it in the eng bay thru the pass inner fenderwell. I had to add line of course when I put a coolcan in it. I think what I will do is insulate (cover) the fuel line under the hood to the coolcan and try to keep that part of the line under the hood cooler. Then cruise around on the smaller air cleaner to let alot of the heat rise away from the carb and maybe even raise the back of the hood a tad to let some heat out. That might help enough and I think I will add a few gallons of race gas every other tank or two. I really dont take alot of long trips to often but it is 45 miles to drive to the track and I like driving it to the track. And most of the time I go racing its a bit cooler out as I hate racing when its real hot out. But I also like to drive it the 90 miles to Carlisle in July and its usually very hot in July like today. I will insulate the fuel line under the hood real well and then throw a gel ice pack in the coolcan and try another 45 mile or more trip. I will have a cooler with plenty of ice and ice packs. And maybe adding some race fuel every other tank will help some also. Thanks for the replies. Ron

Maybe I'm seeing it wrong ( on my phone) but one pic showed the fuel filter on the inner fender with a lot of line, The second pic shows the filter next to the distributor. At any rate that's a lot of line up high in the engine bay, my RR and demon run low along the front frame rail then up to the pump to the front of the engine. I would route it the same way even with the electric pump
Well I felt that low along the frame rail would have the line closer to the headers ?? At least thats why I thought I would do it the way I did to try and keep the line away from the header tubes. Then I though about the fuel line on the outside of the frame rail but I was concerned about the being that close to the control arms on the outer side of the frame rail. Thats why I did it like I did and it has worked good from 2006 until last year when the pump around here got worse. So I will take all the advise hear and decide what I think will be best.  Ron

 I fought the same problem for a while and went to a return setup and never had any problems again.

Fuel pump got real quiet and I could not hardly hear it with the key on eng off. so I wait about 3 or 4 minutes and then the pump starts making its normal noise so I hold it on the floor and the car starts and runs fine.
Are you sure the problem isn't your fuel pump? I have seen this problem on several occasions, especially with Holley Blue and Red fuel pumps. They quit pumping when they get hot, but after a few minutes of cooling off everything is ok.

You always have a constant supply of cool fuel running through the line. IMO this will also be easier on your fuel pump over a dead headed system.
And yes I would put some insulation sleeve over your fuel line.
Here's my system. I can make a pass, drive back to the pits @ 200* and up. Pull the hood off and park my hand on the carb for however long I want

Ron , Heat RISES , so having the line and the filter , mounted the way you do is causing it to get all the heat radiating off the header. I'd put it down low and insulate it , plus put in a return line off your regulator.
where is your cool can mounted ?

I went to a return style system a few years ago due to issues similar to your's w/ pump gas. Made a huge difference.
Back when I was playing w/ different intake manifolds and spacers, the wooden 1" carb spacer I'd been running is a big help also. Didn't realize how much until I drove around one time w/o it and heard fuel boiling out the vents when I got back home and shut the car off.

No as I have had 3 different fuel pumps on it the last year or so and it did it with all of them. Ron

I was concerned that down low would be to close to the headers unless I ran it on the outside of the frame rail but I did not want to run the fuel line outside the framerail up front. I am going to try and insulate the entire fuel line under the hood as my buddy is a comercial AC man and can get me some real good stuff to insulate the line so I plan to try that first before I move the line. The cool can is on the front core support as its about the only place I could mount it. It is close to the rad which I dont care for but I had the problem before I put it on last summer and it does run fine with ice or an ice pack in the cool can. But the ice melts much faster then the ice pack cools off and it is a bit of a pain to keep putting an ice pack in it. Course it does fix the problem. I went to a show last summer thats in PA and is about a 40 mile run so I put an ice pack in the cool can when I left my house and later that night before I left the show I pulled my other ice pack from the small cooler in my trunk and put it in the cool can. It worked good as I had no problems that day but I found a few other times I wanted to do that I found that I forgot to change the ice pack before I left. Luckily it was not to bad a day and it was getting dark as I had no problems then. The cool can works but it can be a pain remembering to put the ice pack in it. Ron
