I've benn told about a fuel return valve in the pump, that has a spring that goes bad. Weather got too cold before I could look into it, I'll probabaly wait til spring to check unless something bad happens. If nobody jumps in here do a little searching for the last couple months...I'll check too.

My friend only changed his oil three times. The truck has 140k on it and it knocks a little. O yeah it has only had two oil filters. The oil guage quit when he dumped kareosine *sp* in the oil and ran if for about 5 min. It still runs great. Has a wierd smell out of the tail pipe and ticks down the road. <br>not the smartest kid but hey he bought the right truck if that is how he is going to treat it. [eyecrazy]

Pinch off your fuel return line .... if it quits ticking it's the overflow valve .. if not check the area around the lift pump. Sometimes they'll tick loud before they fail.
