Installation Notes and Tips

Verify thread size, height, outer diameter, and flow requirements before installation. Prime and install according to the vehicle or equipment service procedure, and inspect the sealing surfaces, drain port, and housing condition during replacement. This WIX 33783 filter is commonly searched for heavy-duty diesel fuel water separator replacement on Volvo and Caterpillar equipment, so confirm the application details against your existing filter before service.
