new to me 84 burb

[68Timber]

Is it a 305? Reason I ask, my parents bought an 83 K5 new with a 305, and it dieseled unless you ran premium gas. It was later given to me, I don't know, we never tried to fix it, just ran premium gas in it. The fuel gauge is likely a ground or short issue, you'll have to trace the wires to the tank to be sure. It wouldn't hurt to check the printed circuit behind the cluster for cracks first, though.

thanks for reply...
truck has 5.7 350 in it. i have not had it very long. only filled up once since purchase. its a 2nd vehicle for me. daily a 94 silverado. but this thing will get its share of drive time.
i will check the ground on tank and hope its something simple like that.
rather not take dash apart right away. if the printed circuit turns out the problem are they available.?
a little cold here in nj right now. but when i get some time and maybe a couple more degrees out there ill try and follow wires for tank.

im pretty sure this truck has not been driven much in last bunch of yrs. think the sticker was 08?? anyway, plugs look in bad shape, im sure wires been there a long time as well at everything else. again, when i get a couple bucks, and decent weather, i plan to get the brakes for front end and some tune up parts then go from there.
