Found out where my other 2 MPG's went

[Dirtymaxx03]

Last couple tanks i noticed my fuel mileage was down a couple mpg's. Well i got to poking around and found out why

the black thing im pointing to that the red wire plugs into, leaks like a siv.

Question is, do i need a whole new filter housing now? Or is there a fix?

 

[JoshH]

Is it coming out through it or around it? If it is coming out around it, it is the o-ring that seals it and can be fixed with a filter head rebuild kit.

 

[Dirtymaxx03]

Its coming out from around the bottom of it. Not up through the middle out the top. So a rebuild kit will do it?

I took mine off

 

[Dirtymaxx03]

You took your WIF sensor off? or ripped that plactic stud out...

 

[THEFERMANATOR]

That's the fuel heater power pass through. You will have to pull the filter head off and rebuild it to reseal it. Also make sure and replace the o-ring under the primer pump as it is probably hard and getting ready to leak.

I bypassed the entire Thing and removed it from the truck.

Just bought an MA rebuild kit and a WIF plug :thumb:

any codes envolved with that? Do you just "rip" it out lol

No codes least on my truck. Just make sure your lift pump filters are adequte to filtering the fuel down to the desired microns

I never got any codes but I didn't rip mine out i unbolted it. :rofl:

 

[arneson]

Shouldnt be any codes. Just un plud the water sensor and it will no longer send a light for water. Im lookin at deleting mine here real soon once im do for a filter change. Dont need the factory since my lift pump has it.

I took mine off (since there is no room over there) and now run the AD filters, and an inline cat filter (based on the writeup by one of the guys on here) works great.

 

[Dirtymaxx03]

there seems to be a bit of confusion. I thought yall were deleting the fuel heater cord plug thing. Im not going to delete the housing cause my fass has no filters.

 

[arneson]

Oh my bad. I thought u meant deleting the whole housing. No clue about the heater plug

Should have no codes either way

there easy to rebuild i have used the madjack raceing oring kits i have rebuilt 2 of them myself one on my lb7 and i just did a buddys lb7 dually that has over 250k on it and it and it was leaking in the same place as urs is

 

[Dirtymaxx03]

already ordered a kit, now i just have to enjoy this shitty fuel leak till it comes in

 

[DMAXfirefighter]

I had the same thing happen to me last fall. Rebuild kit took care of it, and I replaced the hoses while I was there too. Take a good look at them while you're there
