A replacement fuel gauge for classic Massey Ferguson tractors, designed to give a clear visual fuel reading via a scalable display. Drivers and owners can feel confident on long days in the field with an easy-to-read dial and defined electrical endpoints. Is the 52mm fitting and 12V rating the right match for your tractor, and will it swap in without fuss, the APUK Fuel Gauge?
⚡ At a Glance
- • Gauge Readout: Display with scale, uses resistance endpoints to indicate level
- • Best for: Owners of Massey Ferguson 135, 165, 168, 175, 178, 185 and 188 tractors
- • Not ideal for: Tractors with non-standard fittings or that require a 24V electrical system
Simple replacement gauge with a 52mm fitting and a 12V rating. Empty and full are defined as 2 Ohms and 30 Ohms respectively, which set the scale endpoints.
Confident fuel readings - with calibrated 2 Ohms to 30 Ohms resistance endpoints
Empty is specified at 2 Ohms and full at 30 Ohms, so the gauge interprets sender resistance across that range to position the needle or indicator on the scale. The clear scale display translates electrical resistance into an easy-to-read fuel level.
Accurate readings make it straightforward to judge remaining fuel without guesswork. Defined endpoints help diagnose a faulty sender or wiring when readings sit outside the expected range.
Quick, direct replacement - thanks to the 52mm fitting diameter
The gauge uses a 52mm mounting diameter, matching common panel openings on the listed Massey Ferguson models. The matching diameter reduces the need for additional adapters or panel modification during installation.
Replacement is often a simple swap of the existing gauge, saving workshop time. A neat, secure fit keeps the instrument flush in the dashboard.
Designed for standard tractor electrics - with a 12V rating
Specified for a 12V electrical system, the gauge expects the standard tractor supply and sender signal levels used on many classic Massey Fergusons. Electrical compatibility relies on that 12V rating to match sender behaviour.
Compatibility with 12V systems reduces the chance of electrical mismatch when fitting to the listed tractors. Owners of tractors with 12V wiring can fit a gauge without changing the vehicle electrics.
✨ The 4 Key Reasons for APUK Fuel Gauge
- Calibrated Resistance - Enables precise fuel readings with 2Ω to 30Ω calibration
- Standard 52mm Fit - Replaces original gauge without modifying dash openings or fittings
- 12V Compatibility - Works with standard 12V tractor electrical systems reliably
- Clear Empty/Full Endpoints - Helps diagnose sender faults using defined resistance limits

❓ Frequently Asked Questions
Q: Will this fit my Massey Ferguson 135 or 165 tractor?
A: Yes, the gauge is specified as a replacement for Massey Ferguson 135, 165, 168, 175, 178, 185 and 188 models and uses a 52mm fitting diameter.
Q: Can this gauge be used on a 24V electrical system?
A: No, the gauge is specified for 12V systems, so it is not suitable for tractors that require a 24V supply.
Q: What do the empty and full resistance values mean?
A: Empty is listed as 2 Ohms and full as 30 Ohms, which are the sender resistance endpoints the gauge uses to show fuel level on the scale.
🏆 Our Verdict
The APUK Fuel Gauge is well suited to owners of the listed Massey Ferguson tractors who need a direct replacement with clear level indication. Defined resistance endpoints, a 52mm fitting and a 12V rating make it a straightforward swap for compatible vehicles. Long-term value comes from reliable, diagnosable readings and simple fitment that minimise installation time.
