Default Leak off WIF sensor

So, I was changing glow plugs again and noticed my WIF sensor leaking again. I had replaced it a couple months back because it was leaking fuel from the water release at the bottom. I have the filter delete done to it as well. Is it possible the airdog is just forcing fuel out of it and I need to just put a WIF delete cap on? Anyone else ever have this problem? Thanks.

I've got an AirDog pushing 10+ PSI on my Suburban, and the WIF sensor doesn't leak. It's possible you got a bad WIF sensor, or a bad O-ring on it. That, or your AirDog is set really high on the pressure adjust.

I'd put a different WIF sensor in try again. Probably just bad luck and got a bum part.

Common problem

Is your filter a plastic one by chance?

They can also crack and leak quite easy

I double checked the o-ring and filter housing above. It is definitely leaking from the water release. It's a 165 gph, maybe the pressure is too high for the weak floater in it?? I'd hate to buy a new WIF sensor again just to have it leak immediately, when I could buy a billet delete cap and call it a day?

It has a metal delete filter on. I checked it and the seals. Definitely coming from the release on the bottom

Since you've got the filter delete anyway, sure, might as well put the WIF delete cap on. Or just bypass the whole filter head. That's what I do on my truck. Then you don't have to worry about the primer inevitably starting to leak one day.

Kennedy has a nice plug with a drain if you want to keep the fuel head for the fuel heater and the ability to bleed air at the bleeder !

I think I'll just put the delete cap on. XDP has a cheapish one that looks like it'll be good.
