2nd Gen Non-Engine/Transmission F/P Gauge isolator bad

[ichoplin]

I was replacing a "bad" Isspro mechanical fuel pressure gauge the other day and discovered my isolator is bad. It's bad meaning, it doesn't isolate anymore.

I unhooked the gauge and smelled diesel. Also, the once green tint in the 1/8" tubing coming from the isolator was now not green.

Could this have been the cause for my buzzing f/p gauge? I do have a snubber on it too.

My isolator is the cylindrical style, not the flat square style I've seen. Anyone have any experience with other style isolators?



Thanks,

Ian

I've never had a problem, but if your isolator failed, I'd call Isspro. They should replace it.
