I even added a cool can which you cant see in the pic but it is up near the rad on the pass side. I did it to try and see if my problem of the fuel perking would stop. I threw a small ice pack in the cool can and drove 90 miles last weekend with no problems. And I drove around close to home going about 20 miles last Sunday with no trouble. In fact so far I have had no more trouble. So I bought a fuel press regulator with the return line port and plan to install it as I feel it will help also. I really think it comes down to the fuel as I have heard they added more ethenal this year and that it may give us carburated people trouble in hot temps under the hood. I have not had the fuel perking and pushing fuel out the vents any more. It only did it after a hot soak and seemed to only do it for a few seconds. I could just put the pedal on the floor to cleat it out and then it would start and run fine. Well so far so good but I do want to put the return line setup on as I dont plan to put an ice pack in the cool can everytime I drive it. But I figure I will leave the cool can on as it would be a good idea to put some ice or ice pack in it at the track when I go racing just like the old days. I figure with this cheap pump gas it cant hurt to keep the fuel cool when racing. Oh and I finally got rid of that small air cleaner for this drop base. Ron Last edited by 383man; 05/24/12 05:54 AM.

I just ran a 454 with dual Eddy carbs on my test stand and was seeing some issues that I could only relate to heat soak to the carbs. It would also run on during shut down if I let it go to 210 degrees but would shut down fine if it was 200 degrees or lower on the temp gauge. I think two short spacers under the carbs might cure it in this issue. I can't remember what you said in previous posts, but did you see any effect when you put the cool can in with no other changes? The fuel that we have been all used to from years ago is long gone and making us think twice on how we plan a fuel system for the street. and like everything else, some get away with more than others, which I can only think of altitude and quality of gas in those particular areas.

I just tried putting the plastic one on first to see if it helped since the metal fuel filter seemed to get pretty hot and I thought it may be holding alot of heat in it. I just tried this plastic one to see if the fuel stayed cooler since the metal filter stayed pretty hot. But I am changing it back to a metal one. I am curious if any one runs no filter before the fuel pump and just one after the pump and how it has worked out for you. Thanks for the kind replies. Ron Last edited by 383man; 05/24/12 12:14 PM.

I also remove those dense filters in the carb inlets. No problems. My race-gas jugs have screens on their filler hoses, as it's not unusual to see some sediment at the bottom of the jugs. From time to time I'll swab a little gas or lacquer thinner on all the bleeds in the carb body. On any car that sits for a few months at a time - which most of mine seem to do nowadays! - I'll drip a little Sta-Bil into the bowls with an eye-dropper. Haven't had a junk-in-the-carb problem for a long time. FWIW (and don't take this as bustin' your stones), I'm not a fan of hose clamps on braided lines attached to tubing, or for that matter, braided line: too abrasive against paint. I run hardline & fittings to the stuff that won't move/vibrate, and hose to the pumps from the hardline. Too bad you're so far away, I'd plumb your car just to say I worked on it!

I can honestly say that in the early 70's when I started in this hobby and even up to now I never really seemed to have enough money to build what I wanted to (being married with kids) and most of my years I build mild low budget builds. And back then no one used AN fittings on all the fuel system lines and mine were usually stock or very close. Now over the years all my buddies run the high dollar AN fittings on everything and they tell me I am stuck in the 70's when I dont use all the new high dollar stuff. A dinasour ?? Who me ? But honestly with a 6 lb system I have never had a problem using good clamps on good fuel line and never any leaks. I have not had any track officials say anything about the braided fuel line with clamps either. But I have not updated alot of things I still use like the MP orange ECU that still works fine for me. Even though all my friends have to run MSD or something like it. Yea I guess I am still old school on alot of things but if it still works for me it takes me a long time to change. And most of the old school is cheaper. So as long as it is still safe I stick with some of it on my budget. But dont get me wrong as I appeciate anyone's input. One day when the cash is flowing good I will most likely update to all braided line with the AN fittings. I have been waiting a long time though for the day the cash is flowing well.

I love that your car is in the mid to high tens with very little trickery behind the curtains. When I get a chance, I'll take a flick of my engine compartment where if you did not know, you would think I spent a fortune on hoses and AN fittings as it looks pretty PRO-Stock under there. But believe me,my car is just a simple setup anyway. Hope you dip into the solid mid 10's this season. I tell every one that Early B-bodies rule. Respect your elders since they laid down the law way back.

Ron I run just one inline metal can style cleanable screen fuel filter ( I think it's a Moroso )after the pump along the frame rail. Check and clean the screen about once a year. Never any contaminents. Don't think that's a 10 second air filter in the pic . Fastest 300

Ron I assume you have a 3/8 line in the sending unit.. you can solder a return on it Thats what I did when I was running a stock tank. There should be enough room in the bung to drill and solder in a 3/8" return line. Running a return fuel line isn't going to help you with your fuel / heat issues though - especially if you are returning from a regulator that is mounted on the fender well. Fuel isn't cookin in that area. Fastest 300
