Isspro fuel sender

Posted

Hello, I have maybe a year on my isspro gauges and my fuel pressure gauge seems to be acting up. Is the sender an often replaced item? I have a needle valve, snubber, fuel hose plumbed to my sender. My hose is 6 ft long to my sender. At idle it is fluctuating from 11 psi and at idle revving to 2k it is at 18 psi.  Just trouble shooting on where to start.

    I'd be looking at the fuel pressure regulator, filters/strainers, drive belt, etc. Of course checking with a mechanical gauge or other known gauge would be a good idea, too.   Your sender se

    Mine runs barely open, no snubber on about 4' of line to the mechanical gauge. Same as I set it up about 10 years ago.

 Mine needs a good scraping and a bath in blue paint. Yours looks very nice.

Haha, I hear ya. I have some clear coat failure on my horizontal panels. Vertical panels still clean up pretty good.
