Pump Accessories

Walbro makes additional items that may help with an external pump setup.

Mounting Hardware

This little kit has a foam sleeve to isolate the pump noise and vibration.   The kit also includes a couple clamps to secure the pump - $5.

In-Tank Pick-up Filter

If you mount one of these pumps inside a fuel tank and want to attach a pickup filter directly to the inlet, you will need one of these pickup filters.   Walbro makes this filter to press directly onto the 128-3025 fitting - $6.
