Kudos to Isspro
 

My Isspro fuel gauge was acting up either bouncing all over the place or just pegging the dial at 6:00. They are approx 2 yrs old. Finally got around to grabbing a meter and went over the Isspro troubleshooting. As I suspected the sender was bad. My thought was to buy a new sender and possibly send the bad one back to Isspro for repair and have it for a spare. Long story short, Isspro sent me a new new updated sender and snubber :p . Spoke to them on Friday and got it on Monday. I gotta say there customer support is awesome. :-jammin. Got the new one connected and at idle pressure is at 53-55 psi. Santa will be bringing me a new FRx from Clay.

It seems to depend on the nature of the problem. I also had a fuel pressure sender fail out of warranty and they hooked me up with a substantial discount on a replacement. My ESP quit working a couple of years later and I didn't have a friend in the world. If I had it to do all over again, I'd probably go with an AutoMeter setup. Fewer components to fail.

I agree. When I purchased my performax gauges, I did so from the seat of my pants and didn't take into consideration that it would only benefit me if I was to install numerous others.
If the install is only kept to three, then I would look for a cheaper alternative.

I made a similar post a few months ago. I am way out of "warranty" but they sent me a whole new brain because they said there was a design flaw for my build date.
