Is it ok or not run my truck for 600 miles without a primary filter (before fuel pump)? I have a filter between the pump and before the head. I have a FASS (fuel air separation system) that just started to contually blowing the inline fuse. And without the FASS pump working, the fuel fiter on it starts getting air into it in about 40-50 miles. Not too sure why now, as my FASS has always still filtered without a problem when the pump quit. I've had a pump quit before. I have the primary filter head at my shop-600 miles away, and will reinstall there instead of buying one on the road.
NO PRIMARY FILTER
