Finding the right marine fuel-level sender takes more than matching the mounting flange. Moeller offers adjustable electric swing-arm units, mechanical versions with direct sight indication and fixed-depth reed-style senders. Use the part-number chart to narrow the choice before checking your tank and gauge.
Choose the sender design first
Float-arm models 035722-10 and 035729-10 cover different measured depth ranges.
035752-10 is designated for a 10-inch tank and has a direct-sight indicator; a compatible conversion capsule is needed for remote electric indication.
These models have individually specified tank-depth ratings rather than a single interchangeable size.
Moeller sender depth comparison
The depths shown are tank-depth specifications from Moeller, not shipping or package dimensions.
| Moeller MPN | Sender type | Specified tank depth | Calibration / indication |
|---|---|---|---|
| 035722-10 | Adjustable electric swing-arm | 6–12 in | 33–240 Ω |
| 035729-10 | Adjustable electric swing-arm | 12–24 in | 33–240 Ω |
| 035752-10 | Mechanical swing-arm | 10 in | Direct sight; conversion capsule for remote gauge |
| 035761-10 | Reed-style | 9 in | 32–240 Ω; compatible 33–240 Ω gauge |
| 035762-10 | Reed-style | 11 in | 32–240 Ω; compatible 33–240 Ω gauge |
| 035764-10 | Reed-style | 13 in | 32–240 Ω; compatible 33–240 Ω gauge |
| 035765-10 | Reed-style | 15 in | 32–240 Ω; compatible 33–240 Ω gauge |
| 035767-10 | Reed-style | 18½ in | 32–240 Ω; compatible 33–240 Ω gauge |
| 035770-10 | Reed-style | 23 in | 32–240 Ω; compatible 33–240 Ω gauge |
A gauge rating alone does not establish mechanical or application compatibility. Reed-style senders use 32–240 Ω while supporting common 33–240 Ω dash gauges.
Before selecting a replacement
Measure tank depth at the sender mounting opening. For an adjustable swing-arm design, follow the manufacturer's adjustment instructions; for a reed-style model, choose the part number matched to the specified tank depth. Moeller states that the reed sender's physical length is 1 inch shorter than the specified tank depth, so the two figures should not be confused. Verify the five-hole attachment, gauge calibration and clearance inside the tank.
Moeller 035728-10 is the separate five-hole sender gasket and mounting-screw kit. The complete sender models listed above also specify gasket hardware; check the existing flange and installation instructions.
