Exclamation ISSPRO Fuel Gauge

ok, I have a 02 Dodge Sport cummins with an S&B intake and a Edge EZ and 4" exhust and I have a set of meters in the A-piller from Isspro and they are the old crappy Machanical gauages... I got my Boost working shows about 20psi WOT, however, the fuel pressure is what iam having problems with it is the one with the Isolator box and there is anit-freeze in the line from the Issolator to the gauge, now the problem iam having is that I can't get a reading on the gauge i can blow into the line from under the hood and the meter moves and the pressure valve in the issolator moves when i start the motor... i have about 1psi on the gauge when iam driving... now i know this can't be the pump problem cuz the truck always works good and the pump was replaced at 150km and theres 220km on it now.
Just wondering if anyone knows anyhthing about these gauges on how to bleed them or what is wrong..?

Thanks for any help!

VJ,
It sounds like you have some air in the line from the isolator to the gauge. We recommend pulling the line as close to vertical as possible (pulling up the end which attaches to the gauge, while the other end is connected to the isolator), and filling with antifreeze. Before that, you should have filled the isolator with antifreeze. If you suspect the gauge itself is an issue, you can try testing it by hooking up your air compressor and regulating the pressure down within the gauge limits.

Let me know if you are still having problems.

Thanks and regards,

Do you have a stock lift pump, If so it could have died again. The truck will drive with very little f/p, it is just very bad on the I/P. Try using another gauge and hook it to the pump itself.

I have had similar problems when I was hooking up my fp gauge. I ended up taking the isolator out and it works just fine. I have a needle vavle inbetween to control the pulse from the fuel pump. I have heard of a lot of people having problems with the isolators. They are just hard to keep running, that is why so many people take them out.

Agreed, sounds like a dead LP...some last a while, others a few weeks...I never got more than 80k out of one...I would be checking for a dead LP...

This is why I don't use mechanical FP gauges. The electric ones are SO much easier, and fewer problems. I heard the Di Pricol ones, you could go through isolators one a week sometimes.

John,
Sorry you have experienced issues with our products.

Is it an ISSPRO isolator on your FP gauge? We haven't been carrying them that long, and I have a standing order for all failures to be sent directly to me (and I have not seen one yet). Please provide details.

What are the specific failure modes of the pyrometer? What temperatures does it read, under what conditions?

The trans temp gauge sounds like it may be the sending unit. Please provide a shipping address and I will have a replacement sent out to you.

Give us some feedback on your issues, and I will make sure we make it right for you.

I can be reached at 800.888.8065 Ext 3407, or michael |at| isspro dot com

Thanks and regards,
Michael Pliska

I have an electric westech f/p gauge and have never had a problem. The mechanical ones make me nervous having fluid coming into the cab.

I have an Autometer mechanical f/p gauge. The only problem I have is air tends to collect at the highest point before my isolator. It causes the gauge to violently flucuate. It's loud and annoying. I just crack the fitting open every once in a while with the l/p running to purge it.:cheering :cheering :cheering
