Well ran into fuel pump problems again. Threw a NOS one at the unit and its been fine. Then the gauge rheostat gave up. Addressed it on sunday. Turned out it was a dirty terminal and the were crud built up on the float arm contact. That was weird to see. Got that fixed and now the gauge is right.
Also had to move my roommates journey, used the XJ to tow it into the yard for a moment and man that 2wd low, best mod haha. Now I wouldnt do it over a long distance nor want to do it again.
