I cleaned and re-installed the tank with new hoses between the under body steel fuel line, fuel tank and filter head. I also replaced the leaking filter head. Still getting a small amount of air from somewhere but much better. No more hard start in the morning.
Bottom line: Air in fuel on low pressure side - hard cold start guaranteed.
As a permanent solution, I have an in-tank lift pump (Carter or Mopar) on my wish list.
Thank you WWDiesel and Rancherman for your pump recommendations.
After my experience (see previous posts for details) with an in-line "pulse" type pump, I would not go that route again.
A big thank you to this forum. I would really have been screwed without all the knowledge/expertise available here.
Until your new pump comes in, try keeping the tank as full as you can. Try to keep it above half a tank. The higher the level in the tank, the easier it is to 'suck' out the fuel.. and there will be somewhat less overall negative pressure in the supply line.. and less air drawn in.
Glad it's starting better for you!
There is wisdom in keeping your tank full.
"Air" contains water, just in it's evaporated gaseous form. As fuel is drawn from the tank and air is drawn in to replace it, now you have water in your tank. With hydrophilic fuels and additives incl Power Service, and Biofuels, The water is drawn powerfully from the air, and becomes emulsified with the fuel.
As an emulsion, this will not drop out of suspension as it goes through your filter system.
What it will do, is attach to other small-micron sized particles as they pass through the filter, becoming teeny tiny bits of mud / (polishing compound) which, over time, will accelerate wear in your CP3 and all of it's moving components, your injectors, your in-tank lift pump if you have one, and your Fuel Pressure Solenoid at back of the fuel rail.
Even exceptionally fine filtration, while a very important thing, will only stop the physical particles that it can, since the particles have a physical bond with the water, and with fuel it is a chemical bond. Granted, this is all microscopic and damage is relatively slow, but it's still there.
