Hey Ratpack - yep it is Ben, who are you?

Seagull, I have uploaded some photo's of the install to my album - you should be able to access this?
I had the help from a a mate for the custom tank. Pretty happy with the whole job.
It is set up so that if the tank runs dry or faults the car will go into LIMP mode. Which is noticeable when the tank runs dry! Usually have to top up the distilled water tank (8.4L) every second fuel refill.

Thinking of putting an Aquamist set up on my DID Pajero.
