This installation consists of
- Mounting the pump with a provided bracket and hardware (drilling four 1/4" holes at the mounting location).
- Finding an ignition power source at the back of the coach to attach the signal wire.
- Connecting power and ground at the battery.
- Having fuel hoses made locally and attach them to the Fass pump between the primary and secondary filters (this is where the factory lift pump is plumbed in normally).
- Abandon and cap off the fuel lines that go to the factory lift pump.
Hope that helps! We sell a ton of these to RV owners that install them without issue. (It's not a bad install if you have fairly good access to the filter locations).
