Electric fuel system

Are you using any type of vapor return? It would require running a line back to the tank, but it works very well to cure vapor lock with mechanical pumps.

The factory used them on some 440s around 1969-'70. Repops are available by Goodmark, I think.

Also Wix makes a filter filter that will accomplish the same thing. I'm not sure this is the one. The one I remember had one nipple at a 90° angle to the others, but it gives you the idea.
