I know there is a adapter for getting rid of the fuel heater but I haven't been able to find any info on the thread pitches? I have been running the fs1221with out issue until today when the seal for the drain failed. If possible I would like to run a larger filter without a drain. I will be running larger lines with maybe a pusher pump and draw straw.
As for a pump I have been thinking either a fuelab or FASS. FASS has a pump with a preset pressure at 13psi the fuelab setup has a filter and pump in a nice package with a preset pressure at 8 psi.
