Ok guys I have a 2001 5.4 Supercrew. I took the intake off to replace the water pump hose. Trying the truck back together now.

for some reason it seems like I have pressure in the supply line for the fuel rails. I can’t get to slid on. Any tips. The smaller 1/2 line slips on easy.

Any tips would be appreciated. I have put a lot of force pulling forward on it. Seems to go on as far as the first black o ring.

thanks fellas

Marty
