How many of us are there? Owners of Dodge based RV's?

Carburetor only needs 2-5 psi pressure, do not wanna go over what that needle/seat/float can shut off. And Griff is spot on about being close to tank, pumps pressurize much better than suck. And the super high underhood/doghouse temps make the old mechanical fuel pump vapor lock. Pressurized fuel won't boil as easily. Not to say it won't percolate in the carb bowl after shut down, but thats almost impossible to get away from.
