i've got a question . i am using a late model gas tank (87 mitsubishi truck without fuel pump ) i my 40 chev panel truck . first ,how can i check the operation of the sending unit . there are two wires at the head of the unit . one might be a low fuel warning light ? also i was wondering about the volt reducer. i bought the one sold for this application so i can use the stock dash gauge and it has 2 exposed wire ends . what side of the dash gauge does this attach to and how?
