What next?
I have two questions.I have a 1990 f250 4x4, the front lock out hubs have been giving me alittle trouble.They have been kicking out of 4x4 and when you get rolling good maybe 25-30 it all at once starts vibrating real bad.If I stop It will quit,go maybe 200 yards and it does it again.I put brand new warn lockouts on yesterday,everything new,drove maybe 15 miles,no problems,backed up several banks never kicked out worked great.Then today when I left to go back to work after lunch I got maybe 150 yards down the road and i'ts doing it again.Then as I was trying to see about that the truck all at once starts knocking oil pressure goes to nothing and running real rough.I get it home and pull the dipstick and i'ts way up the stick with what I'm pretty sure is fuel.I'ts not water I do'nt think because i'ts not milky looking.My thinking is the mech.fuel pump went bad by it doing this all at once.My question is what else could've made it pump the thing full of fuel that fast.If it was an injector would it have took longer.I'm talking when it started knocking til I got it turned off maybe 3-4minutes.thanks

Pull your dipstick put a drop of oil on a clean paper towel the fuel and oil will seperate in a circle.This works when there is a small amount of fuel and hard to tell sounds like yours is obvious though suspect lift pump.
