I was planning on putting my pumps under the rear seat (driver's side) in my 2000 VLX.
The air space is loosely connected to the bilge and engine compartment.
I wanted to use the Simmers to save money, but I do want to risk of explosion!
Last weekend, JR and I cut the holes (fill, vents and drains) and installed the thru-hull connections. Just need to pump it and wire it now.
