Hi, I have the 3 gage package from diesel manor and my fuel pressure gage isolator just started leaking on the antifreeze side, the seal where it screws together, I was wondering if this happened to anyone before and if they fixed it or if anyone has any tips to fixing the seal. A new one is 80.00 $ and I just don't want to buy a new one if this is a common problem. I would like to keep the isolator and not run fuel into the cab, any help would be great, Thanks

 

I have the exact same thing and haven't had any trouble with mine. If it isn't too old, I'd call them at Diesel Manor and explain the situation. If they still want to charge you, I'd take it apart myself and make a new gasket from rubber sheet material I could buy from McmAster Carr.

 

Noop, I haven't had any issues with that at all and been running the setup for about 3 years.

 

OK I cleaned it up and tightened the 4 screws, topped it up with anti freeze and no more leaks, works perfect again

 

I sealed mine up with plenty of teflon tape.
