Now that I have fitted the boot carpet panels I wanted, I can finalise the washer bottle fitting.

Actually, I started the process with a little disassembly: the two bolts that will hold the rear wing and the washer bottle will need to be a bit longer than the kit supplied items. So I swapped them from M5 x 20mm to M5 x 25mm.

I fitted the washer bottle bracket and pop riveted the assembly together.

I then spent what seemed like ages trying to work out the best route for the wiring connections and hose to exit the fuel filler cover, but in the end opted the position I have seen the factory use. That said, I still needed to remove the plastic from the wiring connection or they wouldn’t pass through the grommets that I was about to fit to the fuel filler cover.

I remember the poor fit my 360R fuel filler cover had with the boot floor and the top chassis rail, something that had to be left to post build check, where the part was replaced due to a sizing problem. I was also expecting to have to put some IVA trim on the top of the fuel filler cover, but my fuel filler cover was a very tight fit, so tight in fact that it would not fit under the chassis rail if it was fitted on top of the carpet, so it had to be fitted under the carpet.

You can also see from the photos that I extended the hose between the washer bottle pump and the one-way-valve, so I could hide the valve behind the fuel filler cover. I made sure the washer hose was tie-wrapped up to the highest point to try and prevent the washer bottle emptying due to a syphon/gravity when parked on a slope. I know I won’t solve all of the problems associated with this washer bottle mounting location, but this is better than nothing, and it’s better than my 360R, which had the washer bottle under the plenum in the engine bay.

Having mounted the fuel filler cover to the boot floor (using two small self-tapping screws) the boot carpet needed to be trimmed around the fuel filler cover. I strongly recommend you make a paper template before you cut your boot carpet if you’re faced with the same situation.
