Side water inlet + outlet for T6.1

[mike2060]

I am looking for a way to hook up my underbody water tank. I thought of routing the pipes to the 230V EHU and ideally add an inlet/outlet combo port on the side of the van. Did anybody seen such combo ports ? Any other recommendations ?

The california ocean has just an inlet cap, which is fine but I'd also like outlet there as well. The tank will have a pump.

You don’t need to cut holes in the van body. The tank can be filled under pressure from under the rear bumper with a standard hose connection and a check valve.
The tank will need at least one small bore vent at the top.

Have you any experience with such configuration? Particularly when filling at a RV fill points - do they offer pressurized hookup that would suffice ?

Would filling in such a way require me to crawl under the car to hook up the hose ?

The tank already has a top cap that acts as a one way vent.

Yes, my van has had the system for years, no need for crawling and no issues.

Oh, do you have any pictures or perhaps a link, if you have posted it here already? I like the idea for its simplicity.

I’ll get some when it stops raining.

Here’s some photos.
They show the hose connection with a cover.
Underneath I can either fill straight through the check valve under pressure, this check valve prevents back flow when the hose is disconnected.
Or I can by pass the check valve with a manual valve if I want a gravity feed from a portable tank.
The two smaller lines are vents from the top of the tank which exit to filters behind the panel under the tail lights. These vent the air out of the tank when filling and allow filtered air into the tank when the water is consumed.
There is absolutely no need to cut holes in the van body, I don’t know why VW or many converters do it, it adds expense, looks pig ugly and compromises the body corrosion protection.
