Frequently Asked Questions About International S2200-S2600 Fuel Tank Senders

Will these fuel tank senders fit my specific International S2200-S2600 model year?

These fuel tank senders are designed to fit International S2200-S2600 series trucks typically manufactured from 2017 to present. However, compatibility can vary based on your specific tank configuration and capacity. We recommend checking your existing sender's part number or contacting us with your VIN to ensure proper fitment. Some model years may have different mounting hole patterns or wire harness connections that require verification before ordering.

What's the difference between OEM and aftermarket senders, and which should I choose?

OEM senders are manufactured to original equipment specifications and typically offer plug-and-play installation with factory-matched resistance ranges. Aftermarket options often provide similar functionality at a lower price point but may require minor wiring adjustments or gauge calibration. Both options work reliably when properly installed. Consider OEM if you need exact gauge readings without calibration, or aftermarket if you're comfortable with potential minor adjustments during installation.

How difficult is the installation process, and what tools will I need?

Installation typically takes 1-2 hours and requires basic hand tools including wrenches, screwdrivers, and potentially a drill for new installations. You'll need to drain or lower the fuel level below the sender location, disconnect the battery, and work in a well-ventilated area. Most installations involve removing 5-6 mounting screws, disconnecting the wire harness, and carefully extracting the old unit. Common challenges include seized mounting bolts and ensuring proper gasket seal. Professional installation is recommended if you're not comfortable working with fuel systems.

Why is my new sender giving inaccurate readings, and how can I fix it?

Inaccurate readings usually stem from three main issues: incorrect sender arm length for your tank depth, mismatched resistance range with your gauge, or improper grounding. First, verify the sender arm reaches the tank bottom without binding. Check that the sender's ohm range (typically 240-33 ohms or 0-90 ohms) matches your gauge specifications. Ensure all ground connections are clean and tight, including the tank ground strap. Some aftermarket units may require gauge recalibration or the addition of a matching module for accurate readings.

How long do these fuel senders typically last, and what causes them to fail?

Quality fuel tank senders generally last 5-10 years under normal conditions. Common failure causes include sulfur buildup from diesel fuel coating the resistance strip, float arm wear from constant movement, and corrosion of electrical connections. Using fuel additives that reduce sulfur content and keeping water out of your fuel system can extend sender life. Early warning signs of failure include erratic gauge readings, stuck readings at full or empty, or complete gauge failure. Regular fuel filter changes and quality fuel help prevent premature sender failure.
