Sender Installation
CAUTION: Do not use sender body to tighten.
If sealant tape or pipe dope is used on the pressure sender, be sure
that the tape or dope does not plug the sender’s orifice.
CAUTION: Extreme caution must be used in handling or working on
or around the fuel tank. It must be worked on only in a WELL
VENTILATED area. Keep all flame and hot materials away from it.
Do not smoke while working on or around the tank. Avoid sliding or
dragging the tank, or other actions which may cause a spark.
NOTE: When installing the fuel sender in a non-metallic tank using a single wire sender,
another wire must be added from one of the sender mounting bolts to the battery ground
(negative post). See
