    Not just you. Hit the Iggy button life is too short to put up with ignorant stupidity that you can control.
    Stan has showed me the light.

    I had the 5/16ths sending unit and line on my 70 Sport Fury GT with a stock fuel pump. I tried to locate a 3/8ths unit, but could not find one. Upgraded the fuel line to 3/8ths and added a Carter high volume fuel pump. ET dropped from 14.5 to 14.15 with no other changes
