Fuel Heater Leak
Well, it is still cutting out a couple of times about 5-10 seconds after a cold start (sitting overnight). After that it's fine and idles and excelerates normal. Starts fine even after sitting a few hours. I went ahead and bled the line at the vp-44 banjo but I didn't get a flow after two lift pump cycles. Put a bleed line on the ouside test port on the filter header and got 4 oz. per pump cycle. It is an oem pump that the mechanic put on after the ip replacement. I'm baffled as to why I didn't get a flow at the ip banjo??? I've got fuel flow because the darn thing cranks up. I'll try the cold start tomorrow and see if I fixed the air in line problem. According to Bluechip's site, my symptoms are air in the line. It didn't start this until the second time I replaced the fuel heater o-ring. A Checked all the fittings and all are tight. If this doesn't work then I guess the next step is to replace the copper washers on the header banjos as I may be getting air there. Want a fuel pressure gauge real bad but can't spend that much right now as I am about retired out and not real sure yet of what kind of budget we'll have. There are mechanical gauges cheaper and I may mount one of them under the hood just to monitor pressure for now. It should plumb into one of the header test ports easy enough. "Stay tuned for more details".
Well, I said a prayer on my out to start the truck Wednesday morning and sure enough, it started and ran fine to work and back. Did the same thing Thursday and today. I don't think it was anything I did so it had to be a miracle.
Evidently there was quite a bit of air trapped that I wasn't getting out on the bleeds. Thanks for the suggestions and help. Now on to another thread for TLC that I need to start giving this old gal because she has to out last me.

Just an FYI for those following this thread: Expoxy is a no-go, at least in my experience. Had a 98.5 work truck with this leak - epoxied around the leads. Seems like as soon as it hardened off it cracked and the leak was back. Glad it wasn't my personal rig, though it WAS my plow truck and left me stuck a number of cold nights with a wrench in hand trying to bleed injectors with frozen fingers...
Good luck!
It would have gone much more smoothly had I been a member of this forum at the time...

When you said "leads", I assume you mean the wire leads entering the element? I could see where epoxy or any other sealant that completely hardens would tend to fail due to expansion, contraction and movement of any type. Also, on Permatex's website, any silcon based sealant is not good either as it doesn't hold up against petroleum based fuels such as gasoline, kerosene and diesel. I used the Permatex brand "High Tack" as it remains viscous and it is petroleum fuel resistant. Mine however was not leaking at the wire leads, it was leaking at the o-ring.
