I'm Awesome
I thought I would share this after working on my carb conversion 350 yesterday . I have a high vol mechanical fuel pump installed....for the first time ever I ran a clear filter in my fuel line going to the pump INLET . I was shocked to see it was about 1/3 full while at best running with this 80 GPH pump ?????? I have never run a clear filter before . So I pulled my fuel lines , blew them all out ,blew the line out back to the tank strainer , disassembled my second filter in the carb inlet fuel line and found ABSOLUTELY nothing wrong. Scratching my head I then disconnected the carb fuel inlet line ran it to a bucket and started the truck and enormous amount of fuel IMMEDIATELY flowed through the filters line etc ?????? So I theorized its got something to do with the needle and seat at the carb . If the carb isnt demanding fuel it cant pull fuel through the filter backstream . I then read on the net several old guys saying this is totally normal -one a 40 year mechanic who said dont worry about it .
