This is kinda not very informative. I didn’t get pics under the van showing the tee installation. I was grimy from the dirt falling from van, and working on gravel/dirt driveway, van not jacked up.

Last weekend noticed one of my rear heater tees was leaking . I fiddled around with it , trimming ends if hose, tightening clamps etc. finally it blew up under pressure testing. I had a spare plastic one and put it in. During the pressure testing I noticed one of the hoses to rear heater was weeping. So at that time I spliced in a section of hose to get by.

This weekend I had new hose and some parts I made. I showed the tees in previous post The hose from the tee under van to the rear heater is nominal 1/2”, but at the heater it swells to 5/8”.

Because of its routing I wasn’t confident I could run 5/8 from tee to heater. Plus there are grommets to pass thru . So I went 1/2” and used the stock hose ends at the heater. Yeah, means another connection.

All went ok, I’ll spare you the details except that I think routing the hoses is harder on Syncro. Plus one of them has a ninety at tee end. I managed to lead the hose well enough to not kink there.

Just a note, yeah the paper on the inside of rear bench is crap. It’s an 82 diesel westy interior inmy 86 syncro… I put in rear heater in my 82 and decided to mount it to one side to maximize storage under bench, so when I used that interior to westyfy my Syncro ….. that’s where the heater went.

Anyway…. No leaks so far

This is Eric. Heidi can explain. The bulb base contacts can be removed if you cut or grind off the plastic holding down the metal circuit traces, so if you have a spare assembly you can pull a contact from it and add it to the one you want an extra bulb. You can trace the current path back to the right connection . Re melt plastic or use hot glue to hold down the trace you bent up for the install.

I haven’t explained that well, but should be obvious from the pics.
