Ok so I bought a udp fuel filter adapter and can not get it threaded on!! It seems to start threading but always is crooked when it does has anyone run into this problem!!
You might've got a defective one. I'm pretty sure they fit test them before shipping out. I took my filter head off and rebuilt it and put the adapter on outside the truck. Maybe that would help if you took the head off? If you can't get it I would get with UDP and get another one coming.So out of all the people that I've looked at this thread nobody has had this issue
