Latest updates:

* I have replaced the O-rings in the lift pump. Although there it held suction and blew pressure, the smaller O-rings were hard and brittle! However, this did not fix the problem.

* So we dropped to the 30 degree mark early last week. I believe my glow plug relay may need a new fuse. Is the relay one of the boxes behind the battery? I have been trying to find a post with a picture of its location but have come up empty handed...

* I have a new clear filter and a new screw-on filter ordered and should arrive on Monday. I may grab a new clear filter from AutoZone tomorrow just to swap it.

Bernhardt - I have replaced the o-rings on the top of the Injection Pump. They were falling apart. I put in o-new rings but they did not seem to fix the problem either. :-( I am thinking about re-torquing them to make sure I applied the correct amount of torque to each. I did follow the tighten, release, tighten, release, tighten recommendations.

DLSSmith - Thank you for your insight! I too was thinking about a fuel flow issue. Alas, even with an almost full tank, she still cranks a bunch before starting. That being said, I am hoping to drop the tank this spring and give it a good cleaning.

I will continue to update as time permits. Thank You all for sharing your knowledge!!!
