What will cause my float bowls to go dry

WHAT YEAR MAKE MODEL is the car.

Tank (non) venting can aggravate this.

This SEEMS to be a combination of "new style" gasohol which boils and evaps more easily, heat, so, vapor lock and fuel boiling off.

There has been numerous "cures."

Make sure your line is tight, no leaks, and new connecting hoses, originally, one from tank to tube, and from tube to pump.

One guy claims a check valve fixed it, but there are check valves in the pump, so, ??

Make sure your line is run away from exhaust heat, maybe get an isolator/ spacer for the carb

WHAT I DID that helped a lot:

Got rid of the mechanical pump and went with a rear mount electric. Added a nice think heat insulator under the carb. Constructed a return line setup with a filter bult for that. Wix shows these, as do others, in both 3/8 and 5/16 metal filters with a built in 1/4" fitting which has an orifice for vapor return.

Wix vapor return: Small fitting MUST be UP. Filter can be vertical or horizontal
