Fuel System Issues?

[vxcp]

Got this followup question recently:

Just curious, did swapping the FPR fix your gauge needle jumping around?

Heres my reply:

Nope that required changing out the in dash fuel and temp gauge unit ( p/n 8972114670 as seen here http://www.catcar.info/isuzu/?st=50&...fHxuaT09MDI%3D ). Took a few months to get the part in and think it had a $200 or so cost. I've seen on the forum that sometimes tightening a screw for the gauge behind the dash can fix the jumping needle.

You could also have a bad sending unit, but I had to get a new fuel pump and sending unit too, and those didn't fix my bouncing fuel gauge.

Just my two cents... My fuel gauge is never right on (except at full) and I have no other problems (except a check engine light for the gas cap).
