Added a fuel filter just before the expensive Injection pump before I start sending vegetable oil through the system. Having the relatively large surface area of the fuel lines and Flat Plate Heat Exchanger (FPHE) without any filtration made me nervous. So I coupled this russel -6 AN fitting Part# 640000:
The filter part# 650130:
The filter has a metal mesh screen that filters to 35 micron and acts as a last minute catcher. The filter can be taken apart and washed if it ever clogs. Having it mated up to AN (Army /Navy) fittings will help with service.
