Just a quick update to 410 (and probably most of the others) Lagoon owners. The WEMA Senders are installed and working perfectly. The Fuel tanks
do NOT require the backing rings inside the tanks
. The Fuel tanks have molded in backing rings and bolt right in. Ohm readings should be 10-180 Ohms and in my case 9" tube lengths. The original VDO sender had "145" stamped on the variable resister inside (what a great place to put the model #) and getting them out was the tough part of the job (5 mins). No interference
issues at the wiring
terminal on the sender to floor hatch
. Again thanks for the replies.
