FP isolator

[sdriv]

I am ready to order my gauge system and have a question about the FP isolator. I am getting the Di-Procal 30 psi gauge and the isolatoer they had in stock is the one from autometer that you have bleed the air bubles out for proper operation. I have heard that Di-Procal is soon to release an isolator of their own. Has anyone had experience with the autometer? Or the Di-Procal if it's out already. Or any info on either type of setup would be much appreciated. Thanks guys. I'm on my way to the dark side!!!!! and it's all your fault. THANK YOU!!

I can't answer your questions about factory isolators....

... but I made my own. I took the aftermarket barbed fitting (that goes to the filter, post filter set-up) tapped it for a 1/4" allen screw, took a 3 cornered file and made a "slot" down one side of the threads on the allen screw. Then I screwed it into the barbed fitting, "farmer" tested it (I put it up to my mouth and blew on it) and then installed on the truck. Pressure is rock steady.

Thats really not an isolator,it will have a dampening effect but there is fuel in the line to the gauge, a true isolator uses some other liquid like anti-freeze from the isolator to the gauge.

My mistake...

I guess the liquid filled pressure guage I have on my tractor herbicide sprayer is some sort of hybred isolator then???

Actually the liquid filled gauges are just that,the liquid inside the gauges is there to dampen the movement of the needle or pointer whichever one wants to call it. It has no connection whatsoever to the line coming in to the gauge, be it oil,fuel or herbicide. I have some hydralic gauges that are glycerine filled so the pointer dont jump around due to pulsations in the line,some gauges might use some other type of liguid.

I'm running a mechanical Isspro EV fuel pressure gauge mounted on my dash with no isolator.

Stainless steel braided line, and no leaks.

No. 2 diesel isn't as worrisome as gasoline, just make sure that all chafe points are protected, and enjoy not having to worry about a sending unit going bad.

Di-Procal isolator

I have heard that Di-Procal is soon to release an isolator of their own.

Call Ken Jones at Diesel Performance, he has the new isolator in stock. (801) 791 2328 It's a no bleed unit.

Steve, all my sprayers have isolators right below the gauges. Many pesticides are highly corrosive and eat gauges. Ever wonder why most sprayer tanks are stainless, plastic or fiberglass?



I don't feel that an isolator is necessary with diesel fuel but if a guy wants one ag equipment dealers have a much better price, around $25. The auto parts guys rip you off $75 or more for the exact same thing. I've never heard of having to bleed anything, it will do it itself quite fast.
