Hi everyone, I just wanted to share some fuel pressure results from a new in-tank pump I installed last week. I purchased part number P06K from RockAuto. It was around 25$ shipped. After installing it, I'm seeing 6 PSI at the carbs (its a spica-converted 78' engine, with a 1985 rear end and tank/in-tank pump) being fed by the in-tank pump alone.
I haven't been able to measure flow-rate, but it is probably lower than the 30 gal/hr necessary for carb operation. I'll be testing this this weekend.
