I'm sure there must be a fuse for the gauges in the fuse box but I doubt that's your problem;
to be certain, do your other gauges work?
Most of these problems are caused by worn-out sending units; with the key in ACC or
RUN, disconnect the wire from the sending unit, the gauge should swing all the way to one
direction (I believe EMPTY but not positive). Then, ground that wire to the frame or body,
the gauge should swing fullt in the other direction. If that test passes, then your gauge and
wiring are good and the problem is in your sending unit, most likely the very fine wire has
worn through and maybe unraveled. Some guys have problems with brass floats that fill up
with gas and sink to the bottom but in my experience, that happens less frequently than the
worn-through wire. If you remove the sending unit, remove the triangular cover (held on with
3 bent-over tabs) and look inside....

Before you buy a new sending unit, drop the tank and manual check the old one. I mean pull it out, and have someone tell you if the gauge changes when you move the lever up and down. Mine turned out to be the little float on the sending unit arm was flooded. I went to the local Ford dealer and they still stock the parts, and they're really cheap. Overall it's an easy job.

Dropping the tank is not as bad as it sounds unless it's full of gas. But going to a bigger tank (I AM NO EXPERT, JUST SHOOTING HERE) If it is deeper then you will have to get the bars to hold it to the frame, and if it is longer make sure it will not impeede with anything else you may have to do some drilling on the frame to change the support holes.

Both of my guages aren't working. Probably because my grand father stuck a garden hose down the tanks to ciphon gas out to keep from going to the store to fill up the lawn mower and twisted it all up to get it in there. GOD love the DO-IT-YOURSELFERS
