Add-on gauges are AWOL!

[dstoops]

Several years ago I installed one of those 3 gauge sets that mount up on the dash. The isspro trans temp lasted about 1 year before quitting. the boost gauge still works but has stuck at 0 since day one. I have to "thump" it after it has set for a while then it works right the rest of the day...especially bad during hot weather. The EGT gauge is made by US Gear. The sensor gave out a year ago as well. I was wondering if it's possible to buy just the sensors for the temp gauges. Anybody got any ideas short of all new gauges $$$$?

Thanks

my isspro egt gauge did that too, and it was new but since i moved it to my newer truck it hasn't done it since.i wonder if in that 3 gauge housing it somehow gets sprung a little ?
