Can we back up to the comment about a last chance filter screen in the lp line? Are you sayin to pull the lp line off the injector housing inlet and there is a screen inside the inlet nipple? I have the same k25 that has a crank no start issue. I have spark at the plugs but I checked the throttle body with the air intake tubing removed and didn't think I was getting enough lp. I have plenty of lp pressure at the line coming out of the vaporizer to the injector
