Bit of an up date and maby an idea for others with the same problem.
I was getting sick of draining the can by hand and making a mess so i made this set up and have tested it for a few mnts before posting it up on here.
All the bits inc the hose came from Enzed so your local should be able to help.
They only thing you may need to borrow is a nut sert kit, they are pretty expensive.
The rest is just hose, a hose clamp, ball valve, 2 barbed fittings and 2 hose support clamps.
The two holes are all rdy in the chassis rail but one needs opening up a tad to fit the nut sert.
Its about 30 min work once you have the bits and then draining the can is a 10 sec job.
