The rail seems hard to pull from the injectors...all fasteners are removed... and bolts..

I'm getting 12.8ohms across the board for the injectors

They are hard to remove. Dry, 25 yr old o-rings are the problem.
I pry the rail up with the wooden handle of a small ball peen hammer.

Replace with all new o-rings, lightly lubed with motor oil, attach injectors to the rails & press down evenly until the rail brackets are down & bolt in place.

If you have liquid water in the fuel rail and this was the engine out of a '90 which had been sitting for two years and which was discussed in another thread, you may have corrosion problems throughout the fuel system.

That might neither be fun nor cheap to repair.

You better get the pumps out of the tank for inspection then clean out the tank. Also, you may need to replace the hard lines running from the tank, foward along the left frame rail.

Get the fuel rail off and apart to see what level of corrosion might be inside.

Might as well scrap all 16 injectors as if they are original, and you found water in the fuel rail, they'll be full of rust.

Best LT5 injectors come from RCEngineering. There are other vendors which sell injectors almost as good. There are many vendors which sell injectors which are s**t.

Hi, Thanks for the reply!!!. The corrosion in the rails is next to none...when I pulled the rails a little bit of water got absorbed into my towel.Then the rest smelled (and tasted) like raw fuel. The tank was removed and cleaned the year prior. The secondary injectors look like S#$T!!!!! I filled the tank full of premium and put a fuel treatment in for any remaining condensation... I plan on running the pump via the red jumper to clear the lines before firing the beast up after I go through the engine.
