When ridding out on the trails, every once in awhile the fuel pump starts "thumping" usually you can get it to stop by just slapping it with your hand.
I figured its probably uround $40 so I'll just replace it and carry the old one with me as a spare.
I called the dealership today and the said $150 for the pump P/N: 4011545
So now I think I better make sure that is the real problem before shelling out the cash.

I am going to stop and get a fuel filter on the way home and give that a try first.
Can anyone think of anything else that could be causing this ????
Or have you ever heard of this before ????

The ranger only has about 80 hours on it.

mine does this also. especially when you insert the key and turn it to the on position but not cranking the engine. it will thump a min and then stop. the dealer said this was a problem from the factory and they "fixed" but it still thumps sometimes, just not nearly as often. maybe ive just gotten used to it and dont notice idk...
