ok, so i put this isolator in my fuel pressure line and now my gauge doesn't work. i have a new diaphragm in it. i do have fuel pressure cause the light goes out. does that little bleed screw go on the fuel side or gauge side? i have it on the fuel side now. is there some trick to bleeding the air out or something??? funny how something like this can have you pulling your hair out. any help would be greatly appreciated, thanks, john

we dont run one, we run a brake line type line and use pipe at the gauge so it wont break or leak inside the car, it works great, i think you might have the isolator in backwards.

The bleeder has to be on the guage side, also be sure you have the guage line as full as possible. I use one on my turbo buick and its kind of a pita, I usually end up bleeding it once a year and still sometimes get wierd readings.

The idea behind the isolator is so you don't have a fuel line that goes into the drivers compartment.

guage and isolator have to be level with each other, line completely full. I even put what I can in the guage with a syringe. If I read your posting right, you put in a new diaphram, where did you find one.
