Glad you have a happy truck again! Ya, i had a sneakin' suspission these pumps came with the extra threads. I think it's because they're worried about damaging the threads in the pump. Its pretty soft compared to the heli-threads they stuck in there....

This is a pretty old thread to ask questions on....
Do you have a 12V or 24V?
What sort of fuel pressure is this 'high output" fuel pump running?

Do you know if the HO pump is even working?
Things like a blown fuse, bad electric motor, ETC can cause them to not work.
I personally hate those electronic HO pumps, They tend to be very unreliable.
The factory cam driven LP tends to last 300,000+ miles and supply plenty of fuel for 400+ HP.
