Frequently Asked Questions About Peterbilt 362 Fuel Tank Senders

Will these fuel tank senders fit my specific year Peterbilt 362?

Our fuel tank senders are designed to fit Peterbilt 362 models from 1980 through 1986. However, tank configurations can vary based on whether you have single or dual tanks, and tank capacity (50, 75, 100, or 150 gallons). Before ordering, verify your tank size and check if you have a 5-bolt or 6-bolt mounting pattern on your tank opening. If you're unsure, measure the center-to-center distance between mounting holes or contact us with your VIN for verification.

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

OEM senders typically use brass floats and stainless steel components, lasting 10-15 years on average. Aftermarket options vary in quality - premium aftermarket senders use similar materials to OEM but cost 30-40% less. Budget aftermarket senders often use plastic floats and aluminum arms that may corrode faster in diesel fuel. For daily drivers and work trucks, we recommend OEM or premium aftermarket. Budget options work fine for show trucks or vehicles with limited use.

Can I install a fuel tank sender myself, or do I need special tools?

Installation typically takes 1-2 hours and requires basic hand tools: a hammer, brass drift punch, and a spanner wrench for the lock ring. You'll need to drain the tank first, which is the most time-consuming part. The main challenge is accessing the sender on top of the tank - some 362 models require dropping the tank slightly or removing the bed floor panel. Always use a new gasket and apply fuel-resistant sealant to prevent leaks. Never use power tools on the lock ring as sparks near fuel vapors are dangerous.

My fuel gauge reads incorrectly after installing a new sender - what's wrong?

Incorrect readings usually stem from three issues: wrong ohm range (most 362s use 33-240 ohm senders, but some use 0-90 ohm), bent float arm during installation, or ground connection problems. First, verify you have the correct ohm range for your gauge. If the sender reads backwards (full when empty), you may have a reverse-sweep unit. Check that the float arm moves freely without hitting the tank walls. Poor grounding through the lock ring is common - run a dedicated ground wire from the sender body to the frame for accurate readings.

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

Quality senders last 8-15 years depending on fuel quality and usage. Common failure points include corroded float arms from water contamination in diesel fuel, worn resistance strips causing erratic gauge readings, and failed float seals allowing fuel inside the float. Biodiesel blends can accelerate deterioration of rubber components. Signs of impending failure include gauge needle jumping, stuck readings at certain levels, or slow gauge response. Regular fuel filter changes and water separator maintenance help extend sender life.
