Ask me for a video I’m not sure if it uploaded or not lol

A couple of my party buses were 2005 IC RE300s - DT466e pushers. The boost pump, if equipped, should be on the firewall on the drivers side of the engine compartment. There should also be two ball valves there but they may be corroded and need replaced. The defront selector at the drivers seat will be a cable-link to another valve that runs down under the front bumper. On my party bus, that cable-link valve was busted all to hell so I just eliminated it. In the summertime I shut off the valves at the engine, so there was little benefit to me of having the valves open in the engine compartment all winter but then shutting off from the drivers seat as well.
In my case I replaced the original rubber lines with FlexFab silicone hose that will hold up better, as well as replacing most of the hose clamps with good constant-tension worm clamps instead of cheap garden hose clamps. Some of your coolant lines already run under the bus so rerouting them out of your bus would be fine, just figure out how to safely get around wheel wells, etc, and be sure to protect them with loom or old hose.
This is a video I made about updating some of the lines on my current bus. It's a conventional, but the theory is the same.
