Greetings gang,
I was just told by the site's cumbersome and useless search engine that my search words were too short??? /ubbthreads/images/graemlins/confused.gif ***?? Ok, so I surrender and ask my question:
Just got my Blackstone report and all is well EXCEPT I have 6% fuel in the oil- makes me nervous. So I figured that 144,000 clicks is a pretty full life for a lift pump and it could have a hole it the the diaphragm and just change it out as a starting point. Just wondered how messy a job is this- am I gonna loose oil and/or fuel upon removal? Next step is to pull all injectors and have them bench tested (although folks I have talked to don't think malfunctioning injectors could put that much fuel into the crankcase, plus they're only a year and 8000 mi. old). Thanks for the help- BTW, where's Okie been?

You may lose a little fuel from the lines when you let them go.There will be no oil comming out fo where the lift pump bolts on.Be sure to follow the instructions per lever orentiation.

Thanks, Paul- yeah I recall the discussions about the need to position the lobe on the crank properly. Thanks for the reminder. A little diesel fuel- no problem...I put a dab behind each ear daily for cologne. I'm goin' in...

Get a small mirror and peer into the hole after Lift pump removal, you easily see the cam.
You will see the the UP position only happens briefly every revolution.
After shutting the beast down, and waiting a few minutes, all of the oil is low, in the pan, no leakage really from the open lift pump port.

I am convinced that a lift pump that "checks out OK, is really leaky. And this is how air get into the fuel delivery system.

yea for as cheap as the lift pumps are and easy to change go with it first then my second culprit would be the INJ. pump

Be sure to use a flare nut (fuel line) wrench to loosen and tighten soft metal fuel line nuts. Soft metal needs a soft touch, specially designed to turn flare nuts without stripping.

Good luck,

My thought is that the lift pump may deliver the pressure and volumn, but due to age, it can allow air into the system. It is a theory, only that.
When a lift pump gets old it is so inexpensive, I see no reason to not replace it.
When someone reports hard starting, and has a lift pump that is original, yet the lift pump "Check's Okay", I believe in theory it is truely leaky!

The weather is great, so I'm out mowing my lawn and mowing M.I.L.s lawn. My hands are still vibrating from the damn "WeedEater". Both places have 1 acre of lawn. Also, my son is in Little League and Cub Scouts. I guess you could call me "A Bad Weather Internet Junkie". This being "retired" is a whole lot more WORK than I was lead to believe, especially in 95 deg weather. /ubbthreads/images/graemlins/shrug.gifOkieGringo

Okie,
Glad to hear you're enjoying life- personally I feel the lawn mower is a midevieval torture device...I'd much rather move snow.
Thanks all for the advice. Install was uneventful, managed to remove the line using a line wrench. Seems to run a bit better now but the proof will be in the next oil analysis. Have about 450 mile pull ahead of me this weekend.
