Sending unit is under the cover on the floor between the seats. You need this and about a 2’ cheater bar. Unlike Transit, fuel tank stays put.

This is a “Prime Example” of a “Forum Gem” of information.

Not something I need ( right now ), but your post here @MsNomer does not escape my admiration & praise !!

Not to exclude the Many Excellent Forum Members that post “Forum Gems”, as there are many.

I assume this is “exactly” what @Belugapilot needed to see, to “get the concept”.

Agreed! @Misnomer has saved many of us from ourselves. (Sent from our Promaster on the Gulf Shore)

What happened with this? Did you resolve the issue? We are looking to buy a Velit heater as well…
They sent the new ecu, simple to change out. No issues since then. I would assume the new units now shipping already have this fix. Overall, happy with the heater and would buy again.

That’s great. Thanks. I want it to work at high altitude - we are going to hike the Appalachian Trail in January 2025. And the Pacific Crest Trail after that. This van will be our trailhead vehicle. What accessories did you have to order if any for the install? We don’t have any heater installed.

Again, thanks for responding. Glad it worked out.

The only thing I used besides the supplied accessories was this turret plate to get through the floor. Turret Mount Plate Heater Floor Base Amazon.com

I mounted mine right in front of the wheel on the slider side. A little tight here but doable. Mine is under the bottom of a cabinet.

Velit says they are coming out with a new wall mounted thermostat. It would be worth inquiring if it is available, the original version I have is by far the weakest link of the heater.

Thanks for that info. We just placed our order with Velit and I responded asking about the wall mount thermostat. Also that turret looks like a good idea. Any chance you could post pics of your install? Or maybe you have already? I went to MsNomers build webpage but didn’t see anything about their install. Just the webasto.

There is a 5 week backorder on this but I won’t need to install until mid to late October anyway.

Here's some pics, hope they help.
I drilled a 5.25" hole through my flooring, insulation, and the metal van floor, the turret acts as a sleeve in that hole.

Wow thanks! That mounting plate looks like it made life easier for sure. I’m definitely ordering one. Still trying to figure out where to put ours. It almost seems like you could mount it anywhere as long as the exhaust and fuel lines are long enough.

How did you get around the kit standpipe issue? Their manual says the standpipe supplied is only for metal gas tanks.

I used the existing standpipe that comes on your vans tank. The heater came with a fitting for this standpipe. Some people say the existing standpipe has too large of a diameter for the pump to draw, but I have had no issues at all.

Have you used it at high altitude? Manual says using Promaster aux fuel port will be a problem above 5000 feet.

Thanks again. Really great pics btw. Helps a lot!
 
Did they say anything about the new thermostat?
I asked

Does this kit include the new wall mounted thermostat? If not how can I order it?

I got this reply

"Hi Ken,

No, we don't have external thermostats for the air heater. But our next batch of air heaters, which will arrive in mid-September, can be upgraded to Bluetooth controllers for free!

Regards!"

We have the same turret and we're getting ready to install on driver side under where our galley is going.

We have 1 inch of XPS and a half inch plywood resting over the metal floor but not screwed down or anything.

How did you seal your turret airtight against the floor? Don't want any carbon monoxide leaks...

Did you cut away the flooring and insulation into a square above the metal floor? A square this fits into?

And then there are the metal floor ribs. How do you get a seal against those?

I used the hole saw to drill through the plywood floor, insulation, and van metal floor.

Then attach the turret to the heater, secure all tubes and hoses to the heater, feed all those through the hole and screw the turret to the plywood. From underneath I sealed between the OD of the turret and the van floor with silicone. You could also put a bead of silicone under the flat plate of the turret before screwing it down but I didn't.

How did you run the 12v wiring to the fuel pump? Do you just drill an extra hole in the turret and route it thru?
