What carburetor are you using. Some can use only gravity feed. I have always used the Facet with the Ellison carburetor and have never had that problem. I installed new Facet pumps for my new Ellison EFS-3A that I am using on my new Roy's Garage Corvair engine and while probably not necessary, installed a very nice small and light Holly fuel pressure regulator that I got from CPR Performance Parts here in Columbia, SC. It also has a port on it for installing a Fuel Pressure sender, in case you want to know what your pressure is. I will be posting pics of my new Firewall, here in a few days.
PS: I picked the Sensenich prop up from UPS this week, and the Ellison is scheduled to arrive on Wednesday of next week, and the plan is to run the Corvair on the Black Bird, the following weekend. Who knows, I might make the gathering with the Black Bird after all. See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2011 - KR Gathering in Mt. Vernon, Il - MVN There is a time for building and it never seems to end. Daniel R. Heath - Lexington, SC -----Original Message----- It is the Facet that has been recommended by several people. When first installed, I noted that it would nearly flood the engine and that an immediate leaning of the mixture was required whenever it was turned on. I solved this one by installing a 5/32" bypass line from the pump outlet back to the header tank. Mixture adjustments from pump on to pump off are now minimal.
