Will these fuel tank senders fit my specific year Peterbilt 379?
Our fuel tank senders are designed to fit Peterbilt 379 models from 1987 through 2007. However, compatibility can vary based on your specific tank configuration. Most standard 379s use either a 5-hole or 6-hole mounting pattern. Before ordering, check your existing sender's mounting bolt pattern and compare it with the product specifications. If you're unsure, our customer service team can help verify fitment with your VIN number.
What's the difference between a 0-90 ohm and 240-33 ohm sender, and which one do I need?
The ohm range must match your truck's fuel gauge specifications. Most Peterbilt 379s manufactured before 2000 use the 0-90 ohm senders, while later models typically use 240-33 ohm units. You can verify this by checking your gauge cluster part number or consulting your owner's manual. Installing the wrong ohm range sender will cause inaccurate fuel readings or gauge malfunction. When in doubt, test your existing sender with a multimeter or contact us with your truck's serial number.
How difficult is it to install a fuel tank sender, and what tools will I need?
Installation typically takes 1-2 hours per tank and requires basic hand tools. You'll need a socket set (usually 7/16" or 1/2"), screwdrivers, and a drain pan. The main challenges include safely draining the fuel tank (recommended to be below 1/4 full), accessing tight mounting spaces, and ensuring proper gasket seal. Many customers report the driver's side is more challenging due to limited access. Always disconnect the battery before starting and use proper ventilation when working with fuel systems.
Are these senders compatible with both aluminum and steel tanks?
Yes, our fuel tank senders work with both aluminum and steel tanks, but the mounting depth can vary. Standard senders typically accommodate tanks from 19" to 26" in depth. Measure from the top mounting surface to the bottom of your tank before ordering. Some aftermarket or custom tanks may require adjustable-arm senders or modification of the float arm length. Extended cab trucks with larger capacity tanks often need the longer arm variants.
Why is my new sender giving erratic readings or not working properly?
The most common issues are improper grounding, incorrect ohm range, or damaged wiring. First, ensure the sender is properly grounded to the tank - poor ground connection is the leading cause of erratic readings. Check that all connections are clean and tight, including the ground strap from tank to frame. If readings are still incorrect, verify the ohm range matches your gauge requirements and inspect the wiring harness for corrosion or damage. Some customers find that cleaning the fuel gauge connection at the back of the instrument cluster resolves persistent issues.
