So your saying these chaps are wrong ?
TBH my monies on @oldiebut goodie !
Stuart can be wrong!
I can show you a T5 pump and prove what I say that there is a non-return valve and see post 43 and post 37.
This is for use on T6 vans with Adblue, I presume they must have a different sender unit
So does a T5 have the same pump/sender unit as the T6 with adblue ?
What has the Adblue got to do with it? We are talking about the fuel tank pump nothing else. I cannot see why you are bringing Adblue into it.
The T5 through to the T6 have the same unit. It isn't until the T6.1 that the extra fuel take-off appears. But, they all have the non-return valve present, maybe there are subtle variations as with all products, like the cable connections but the basic pump and function are the same.
I don't know what you are trying to get at and say here.

If anyone needs a dip pipe and the fuel sender seal, I have a spare available. I got it just in case my nipple connection didn’t work.
Would this part do the job of step-down for fuel line? >> 2 X 10mm-8mm Car Hose Reducer Converter Connectors Fittings Joiners Multi Use 5081946763018 | eBay
If not, could you give me a link where I can buy the step-down joiner in your image above?
I'm going to try the t-piece to tap into the tank for my diesel heater using 1pcs 7.89 ID6 Female Car Fuel Line Hose Quick Release Connector
I understand they maybe issues but seems easier to try this before I start dropping fuel and adblue
tanks to supply diesel from the main tank to heater
Thanks
You need step down for 8mm to 4mm not 10mm down to 8mm. The van connection is 8mm and the heater connection 4 - 4.5mm.
Thanks..much appreciated
I bought the t-connector bit to do this job rather than drop tank. With the NRV in place then I assume any fuel the heater would draw would be in the return line and drain the fuel filter. Then it would cut out when it drained said fuel filter. When the engine is started will the fuel filter fill up fairly rapidly via the fuel pump, or would it have trouble starting until the filter was primed with diesel again?
I need to take the plunge, I know, and drop the main and adblue tanks at some point
I don't know - you may well have problems. Personally I would do the job right once. I would fit everything but the fuel connection and leave that until you can run the tank down low enough to do it at your leisure. It isn't as though you will be needing to use a heater for a good few months yet.
I asked Autoterm whether it was a recommended was of connecting on Ad blue models and they confirmed it was. I haven't had any issues. I don't run it all night though, probably 4hrs is the longest it's run without me starting the engine
What has the Adblue got to do with it? T5, T6 and T6.1 all have the non-return valve so Autoterm are wrong still! Ask them how they get their fuel past the non-return valve then other than draining down the fuel line.
Yes..think I will run all the pipes and relocate heater wiring, pump and filter then leave the white fuel line close to the sender unit until I get the tank level really low. However, as an experiment, I might temporarily fit the t-piece and see how it goes. As the diesel heater only sips fuel, I wonder how long it would last until it drained the van engine fuel filter. I suspect what is happening with some, who say they have not had issues, is that they only have it on for a short time then start the engine before the heater has sucked all the fuel out of the return pipe/engine fuel filter.
Just for interest I was out the other night and put the heater on in the morning. My new Renogy battery and app showed a 9 amp draw on startup then once my Autoterm was running at full chat on full heat it was registering 0 amp draw on the Renogy app. I guess there must be some draw for the pump, but Mr Renogy thinks it’s negligible, so I guess there’s no real need to start the engine once it’s running. I’ll test it further when I have it set on the thermostat so it will fire up more frequently.
Interesting though.
Although her indoors has now put a ban on any van batteries conversation in chez bigsi.
When I was a teenager a mate's girlfriend banned us from talking about fuel pumps - over 50 years later I can still wind her up by mentioning them!
There is a 2A draw once the glow plug goes out.
Starting the engine idea, was to shove some more diesel, via the fuel pump, into the van fuel filter as the diesel heater sucks it out of the return line and inevitably the van fuel filter because the pesky NRV stops us keeping the diesel heater being supplied from the van fuel tank.
I have been banned from talking about how many watts I'm getting from solar into my Ecoflow Delta 2.
I agreed, but only if she stopped talking about curtains.
Hi new here just fitted heater on 2xt6.1 using t piece from mellor on line (Eberspacher/Webasto/MV Adblue return line fuel connector T6.1, Night Heater Kits, Eberspacher, Webasto, Mikuni, Durite) both are allowing fuel to pass into heater when heater not in use removed one yesterday as I could see a drip from below vehicle there was just shy of a 1ltr in the heater had made its way out the exhaust port a real mess did some test,s with van on ramp heater out the way fuel line post heater pump in a jar when idling no fuel emitted raise and release engine speed small drip sit at 2000 rpm constant small drip
Has anyone experienced similar? Thanks in advance of any replies and info
