Question type: Maintenance & Repair

I'm having to change fuel filter quite often. Runs good, go out the next morning cranks
good but it won't start. Change and prime the fuel filter cranks right up. Then another six
to eight weeks have to repeat the process. What could happening???

Something doesn't sound right. Is the filter actually getting clogged up? Electrical issue? Weak fuel pump?

No electrical issues. Filter not clogged up, but as soon as I switch the filter it starts right up. One thing I've noticed the last couple times it's happened, I feel a vibration in the cab. I've already got it started today and the vibration is gone.
