Front Mideship Side and Rear Fuel Tank Sending Unit for Ford
This unit is designed for Ford F-250 and F-350 midship or rear tank configurations from model years 1994–1997. It is best for Ford owners needing a direct midship or rear-tank replacement that preserves gauge accuracy and fit. Choose this if your truck uses a midship or rear tank arrangement and you want a straightforward swap that matches OEM geometry. A potential limitation is that fitment is targeted to specific year ranges, so verify your tank position before purchase.
Marine Fuel Sending Unit for 4–28″ Depth Tanks
Best for marine vessels with shallow to moderate-depth tanks, this sending unit supports accurate fuel gauge readings and is adjustable by cutting to match tank depth. It’s suitable for boats, RVs, and other marine fuel systems where space is constrained. It is best for boaters who need a flexible installation and straightforward depth customization. Limitation: some installations may require careful alignment to ensure correct gauge readings in variable sea conditions.
Marine Fuel Sending Unit for 6–12″ Depth Tanks
Designed for deeper marine tanks, this sending unit shares flexible depth adjustment and rotation features. It’s better for boats with 6–12 inch tank depths that require a compact assembly yet reliable gauge performance. Choose this option if your boat’s tank sits deeper than shallow models. Caution: ensure the center screw and rotation mechanism are tightened correctly to maintain gauge stability in rough conditions.
A-Premium Fuel Tank Sending Unit for Chevrolet and Oldsmobile
Best for classic GM cars and trucks, this unit provides broader vehicle fitment, including Buick Century, Malibu, Monte Carlo, Oldsmobile Calais, and several Pontiac and Grand Prix models. It’s a good all-around GM option when restoring older vehicles. Best for owners seeking a single sending unit to cover multiple GM fits. Limitation: some compatibility notes reference older reference numbers; confirm your exact model year and trim before purchase.
A-Premium Rear Fuel Tank Sending Unit for Ford
Specifically noted for Ford F-250 and F-350 models from mid-1980s, this unit targets midship or rear tank configurations with a 19-gallon capacity note. It’s best for Ford owners who need a compatible rear-tank sending unit with clear packaging and edition references. Caution: verify bed length and wheelbase as noted in the product details to ensure proper fitment.
Buying Guide
Key considerations to guide your selection:
- Tank type and depth: Is your tank shallow, mid-depth, or deep? Choose a unit described as adjustable or specifically rated for that range.
- Vehicle fitment: Confirm the exact make, model, year, and tank arrangement (midship, rear, or front) to avoid incorrect replacements.
- Gauge compatibility: Ensure the sending unit is designed to work with your existing gauge system and fuel sender wiring.
- Installation notes: Some units require cutting, rotation, or screw adjustments; plan for potential minor modifications.
- Durability and material: Plastic housings and robust connectors typically offer longer service life in rugged environments.
What to check before buying
