Is there a pressure regulator or somthing in the VB that may cause the problem that can be done in chasse to repair it.I hate to rush you but need the truck back on the road ASAP like yesterday.I can get a reman but that will take me 4 days to get here don't have the time.(unless I have to) can you please help thankyou Pro-pet :cool:
