After looking a a gauge reading zero after a fill up, I took a look around here and found that the sending unit is a common point of failure with the original design. Sent a note to Grady asking them the proper length for the sending unit. for my application it was 11.5" long.
Ordered a new one from Wema. $72 after shipping.
Took the old one out, clipped off the connector and soldered it to the new sending unit. Added some heatshrink around the connection. Tested it connected with the float at various positions and the gauge readings were perfect. Dropped it in the tank with the included new gasket. Tightened up the 5 screws (not too much torque - they're only threaded into the tank skin - about 1/8" thick of aluminum)
All in all - about a 30 minute job.
1998 248 Voyager.
