Adam,

Download your Data Card from https://www.lastvin.com/ and look for:

HZ9 Heater booster
KL1 Sender uni (fuel) for auxiliary heater

The first is the eSpar heater and associated wiring, the second is the fuel line tap for the heater. You may have KL1 without HZ9.

Keith.

Tap in a couple of inches below the existing espar fuel pump using 6mm 90 degree 3 way brass tee. I've just installed mine like this.

Yes, that is perfectly normal.

It just means that your van was not fitted with a heater or with the aux fuel pipe at the time of manufacture.

This doesn't stop you from being able to do what you want - it just means that instead of being able to use existing fuel lines you are going to have to make some yourself.

Mine also didn't have any so I fitted a standpipe into the tank and it's worked perfectly.

I've been trying to find the thread / pictures that someone had posted showing the best positioning for the standpipe. They carefully drilled a hole into the fuel pump assembly cap.

I can't find it now. Perhaps a bit of searching or perhaps someone else can find it and help you.

I hadn't really considered it very carefully and simply drilled straight into the tank itself. While this has worked perfectly it was pointed out to me that it creates a weak point in the tank and over time it could lead to cracking.

Tons of threads on this subject, not alot of information on actually doing it. Many people realize that they have the aux tap and then the thread dies off.

Dennis has repeatedly commented to use Webasto part no. 5000553A and to not drill a hole in the actual fuel tank which might lead to cracking in the future, but to drill into the fuel pump lid and add the standpipe.

This is the thread that I found that had the most amount of information....

https://sprinter-source.com/forum/sh...ad.php?t=62096

A friend of mine also just installed an aux fuel tap and used this part...

https://www.ebay.com/itm/Webasto-fue...cAAOSwZ2FcQi1P

Which looks like its not an original Webasto product, but aftermarket, YMMV.

Ill be dropping my fuel tank this weekend and installing a home made standpipe.

So the only way to tap in is to drop the tank?

Yes - if you don't have the aux fuel line already integrated in the cartridge then you need to drop the tank to be able to get access to drill it and fit the standpipe.

I've searched and searched and I even found a post from someone else saying that they'd seen a pic of how to drill the cartridge somewhere on these forums - but can I find the actual pic?

I'm sure I've seen it because I remember thinking that it made so much more sense than what I did and that if I was to do it again then I'd definitely be drilling the cartridge.

Maybe this thread can finally become the 'how to' one with pics!

Dropping the tank is not difficult but I would suggest that getting as much fuel out of it before you tackle the job would be very strongly recommended. If I was doing it again I would probably put a trolley jack under the tank, unbolt the securing straps and then gently lower the tank until you have good access to the fuel disconnects. Once the tank is completely uncoupled you should be able to just slide it out on the jack.

I also found the cartridge really difficult to remove initially. I applied some silicon spray to lubricate the thread and then pushed down on it as I turned it. I have no idea if it was the lubrication or the pushing down which made the difference but it was like when you struggle with the lid on a jar and then someone else just pops it off like it hadn't been put on tight enough....

Yes I agree with all the others, perfectly normal not to have either. It all depends on which state it was originally ordered for as 'hot' states did not seem to see the need for additional heating.

And again I agree with the others, the ONLY way to install a fuel pick up for your heater is to drop the tank and fit a standpipe through the top flange of the fuel sender unit. NEVER drill through the carcass of the blow moulded tank as you will almost certainly create a stress raiser and the risk of future problems.

One final point to make is that I believe the KL1 sender is optimised to read the fuel tank level from the float and hence will include any fuel used by the diesel heater.
Without the KL1 your T1N may only move the gauge based on the calculated fuel used by the engine and hence may not respond correctly to the amount of fuel used by the heater and hence could show you have more fuel remaining than you actually have. Others may be able to confirm or correct my assumptions.

Keith.

I just find it strange that I have the button on the dash for the factory auxiliary heater. Lights up when you push it too. Stranger things have happened. Kind of a disappointment. I wish there was some way to tap in without dropping the tank.
