Fuel Vaporization Using Eddy Carb -- In-Line Fuel Pump Question

What helped me "before" I went EFI. That in itself is a convoluted story LOL

Carb spacer as mentioned.

Consider blocking the heat crossovers or even going to an air gap manifold (I did not)

Pay considerable attention to fuel line routing and you can buy insulation sleeving (ceramic) if needed)

As mentioned rear mount pump. However pay attention to pressure. You don't want excessive pressure blowing past the needles

LAST and THIS IS quite effictive.........Construct yourself a fuel return system. Wix makes fuel filters with built in vapor return orifices. 33040 (5/16) or 33041 (3/8) filters have a built in 1/4" fitting with a return orifice

You will of course have to 'string' a second line back to the tank and devise a return into the tank. A few ways to do this.

Also, engine problems causing borderline high running temps, take a good look at that.


In the meantime a "stop gap" work around.....put an accessible toggle to turn off the pump. As you idle into a parking spot, learn to anticipate your short term run time and turn off the pump to run some fuel out of the carb.
