Richie,Fits onto a 1" hose so that the inside diameter is exactly the same and waterflow will not be restricted. I removed rear cover behind seat, loosened front hose clamp, pulled hose out from behind, installed valve, then shoved hose back through front behind, and finally reconnected hose up front. Make sense?
I'm going to tackle this job but not sure which panel you removed. Do you mean
under the seat or the body color panel in back of seat. If it is the body panel I can't see how you did it without taking everything apart.
