Anyone ever had a standard holly float get crushed by high fuel pressure (15psi) with a boost regulated regulator on a blower application? My engine guy said I need phenolic floats that come in the marine conversion kit on ebay for $62 each. I have never heard of this. I just bought 2 new holly 750 blower carbs and know I need to swap the vents to j tubes, but the floats too? I am ok with spending the money but I am curious.
