2nd Gen Non-Engine/Transmission Fuel filter housing leaking

[SHobbs]

You just have to love the little frustrating things in life. Last Sunday when I arrived at my destination in CO I smelled fuel after I shut the truck down. Upon further investigation I discovered everything on the stock filter housing decided to start leaking. The water in fuel sensor, the fuel heater and the water drain valve as well. Fuel was dripping everywhere so basically the housing was useless. Luckily all my fuel comes from my auxillary tank in the bed which is filtered before entering the factory tank so I just removed the factory filter housing and ran it that way.



Are there seals or o-rings that can be replaced for the water in fuel sensor as well as the fuel heater? I know there are on the drain valve being I have replaced it twice before.



Thanks

Scott

Scott,
I just checked the factory shop manual. All three have O-rings, I have only had to change the drain which has two and the water in fuel a couple of times in over one million mi. on two 24v 2nd gen.
Good Luck Capt Phil

Ok the factory housing is done. I put a couple of filters on the frame and upgraded to a Raptor 150. I know the Carter pump does not have a prayer keeping the pressure up where it should be with the filters I installed. After looking through the parts list I see a 12mm X 1/2" Male SAE J2044 quick connect fitting. The instructions show to insert this fitting into the filter housing which I believe is the same size as the VP44 inlet. Refresh my memory, this fitting also fits into the VP44 supply inlet, correct? Everything else looks pretty straight forward and should be pretty easy. Just wanted to make sure on this fitting.



Thanks Scott

m2 cents

You should use a screen type filter on a suction side of the lift pump. Such as a NAPA one listed in the farm tractor section (IH and Deere).

the threads on the stock lift pump is 12mm x 1. 5. It is a straight thread and must be sealed with a washer or o ring. The VP44 may be the same. FYI in english we have threads per inch, fine & course. In metric the 1. 5 stands for how many times you must turn the fitting to go 1 thread diameter deep or 540 degrees to go 12mm deep.

There is a screen on the inlet side of the pump, got that covered. Only problem I have now is my darned filter heads are seeping a little. Thanks for the information.

I think either I did not understand your post or you made a mistake. Metric threads are specified as the diameter in millimeters X the pitch in millimeters (the distance from the peak of one thread to the peak of the next thread ). A 12mm X 1. 5 thread needs to be turned 8 complete times to go 12mm deep. 1. 5 turns to go 12mm deep would be a very steep thread.
