You very likely don't have a problem. It is stated that it can add to a problem by being an easier fuel to boil/perculate. May never have a problem or you may on a hot day. Not all are the same.


Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!

use a carb spacer and you would have any problems, that or one of those 3/8" fat gaskets.



Yep, 3-4 guys said that already, and some of them had additional info/ideas, too.


Parts I seek: driver doorpanel, 65 Sport Fury, prefer black, needs to be 7-8 on 10 scale, might buy set 16" x 6" Dodge truck wheel(s), from early 70s?, takes 9" dogdish - need for a research job so cheaper is better. 69-73 C-body caliper brackets and/or splashields Send a PM.

Jetting sounds lean, that's what makes it surge and will cause it to run hot. My




Not always the case....if you are running a vacuum advance and to much timing, that is normally the first thing to look at. Then if that is where it should be, go to the jetting.

In addition to insulating the carb, a return line to the tank after the pump will help keep cool fuel circulating. The easiest way to do this is with the "3 prong" fuel filter with the return line taking some fuel and any vapor back to the tank. That way, cool fuel will be supplied even at light throttle.



I have to admit, I've never heard of this trick as a solution - good stuff! I was just talking to a young guy at the parts store who was commenting on how no performance mechanical fuel pumps have a return line (which is the situation I'm in as well) to help with vapor lock. I'm currently modding the fuel delivery system and this just may get worked into it. Thanks for sharing!
