My manual lacks adequate instructions. What is the order arrangement of the
I have cleaned all connections, and bought new 5/8" nylon retainer. I
bought two new O rings for each tube size; those tubes measure 5/8" and 3/4"
O.D. (Not metric!) The 3/4" retainer was unavailable at the store, but the
old one is OK.
I noticed a fiber washer fell out of each joint, upon disassembly yesterday.
There were two O rings on one, and probably only one O ring on the other.
What is the standard sequence of parts installation? How many O rings? Why
This installation must be done in an inconvenient place, so I can't get a
good look at progress.
Yesterday, I removed the two connections with great difficulty. I acquired
the forked removal device, to no avail; it was too big, even though labelled
for my vehicle. I used my bare hands. It took over an hour of struggling.
Putting it together should be easy. I just don't want to make a mistake and
have to disassemble it again.
Sorry I missed this... yes, you are right. there's a plastic or nylon spacer
between the O-rings
lube both the O-rings AND the tube
FYI: Silcone lube is superior for the purpose. Cheap at lowes or Home Depot

Yeah, I was wondering about lube. I have a fine silicone lube intended for
plumbing joints, which I bought at a swimming pool supply. This is what I
plan to use, even though I am taking the chance that it will stand the high
temperature of the heater coil flow. Swimming pool plumbing never gets that
hot, certainly! But this silicone grease seems to be far superior to the
brown waxy stuff I use on bathroom faucets.
Turns out I have to buy a 3/4" retainer, so I'm grounded until tomorrow
I appreciate your concurrence on this. I found a less-than-explicit picture
in my manual, and it lacked adequate captioning. I continue to be amazed at
how far the authors of manuals go, only to stop just short of adequately
explaining some things.
I looked up the recommended Ford lube, and it was described as some sort of
highly viscous siloxane:
ST-29 Organofunctional Dimethyl Silicone
ST-29 is an extremely stable polysiloxane copolymer fluid with no chemical
additives and a
viscosity of 24,000 centistokes.
This fluid is similar to ST-24, with a much higher viscosity.

instruments - Stable polysiloxane copolymer fluid - No chemical additives
