What should I know before I install the WDPART pump and filter?

Installation is designed to be user-friendly: the wiring harness measures 13 inches and connections arrive covered with dust caps to protect contacts. Remove dust caps before connecting, thread the filter onto the pump inlet by hand, then use a wrench to snug the joint—avoid overtightening which can damage threads. If you’re unsure, WDPART’s support team can guide you through verification and setup.

• 13-inch pre-attached wiring harness for direct hookup
• Dust caps protect ports during shipping—remove before installation
• Hand-start filter threads, then tighten with a wrench without over-torquing

What performance or quality checks were done before shipping?

Each pump and filter pair is factory-tested, which is why you may notice a small fuel residue inside the assembly—this indicates the unit was primed and inspected for leak-free, functional operation. The kit is packaged to prevent contamination in transit and to arrive ready for quick replacement. If the part does not match your expectations, WDPART customer service is available to help sort part numbers and ensure the correct fit.

• Factory test-run leaves a small, normal fuel trace inside
• Preinstalled dust caps and secure packaging to prevent debris ingress
• WDPART support team available for compatibility questions

How long should I expect this replacement part to last in regular use?

Longevity depends on fuel quality, operating hours, and environment; replacing worn fuel pumps and filters at manufacturer-recommended intervals helps maintain generator reliability. This WDPART kit uses materials and design intended for OEM-equivalent service in Onan generators, but regular inspection and timely replacement of the filter will extend service life. For high-hour or harsh-environment use, plan periodic checks and replace the filter sooner if contamination appears.

• Service life varies with fuel quality and usage patterns
• Regular filter checks preserve pump performance
• Designed as an OEM-equivalent replacement for routine maintenance
