I just replaced my V3 with a brand new V4 and cannot get more then 18psi unless I pinch off the return line. Does this mean the new purge valve is bad?

If pinching the return to veg tank from the V3-4 allows fuel pressure to raise a lot then yes fuel is leaking thru Purge Valve. First electricly unplug the purge valve and retest first.

have you tried bumping up the pressure on the regulator? my friends 5.9L dodge with a V4 was having the same problem after he changed the prescreen and filter. we tried everything and could not get it to pressurize. jay recommended he bump the pressure up no more than 1/8th of a turn and it worked immediately like a champ and has been working flawlessly ever since. he was saying that sometimes the pressure will be just right at that cut off point for low pressure/auto on and will not turn on or will go back and forth.
