Fuel hose

[Grubscrew]

Hi there.
Been along to VW, and picked up the auxiliary fuel pipe which will go from the spare spigot outlet on the fuel pump housing ( on top of fuel tank).
At £13 it wasn’t expensive.it’s black hard nylon type, and overall diameter is 5mm. One end has the tank connector, and the other end is a reinforced straight bit ( which has a tube stiffener in it) which will ultimately go to inline filter then auxiliary pump to the heater.

Looks good and ensures that you have a decent pipe over the top of the tank. I've had the rubber joint at the tank end from a kit supplied with a heater split only after a few months. It's pain then to drop the tank again just to fix that!

So I deduce the tank definitely has to be lowered. The other thing is : is there then a pipe already in place which has been factory installed inside the tank that will in turn such the fuel up.?

 

[Pauly]

Thats the crucial question !!

I think its highly likely, if its the same as the newer transporters then they seem to have one there ready to connect onto but cant be 100% until you can find someone that has opened one up and can confirm

May be worth checking some of the FB pages and see if anyones has tried already ?

Hi Pauly.
Thanks for that. Even the picture I have of a second hand unit doesn’t quite show it…..I don’t have the gall to ask the seller to photograph the unit at a different angle

If you connect the new pipe and blow into it you will hear bubbles in the diesel if there is a pipe to the bottom. Sorry, lateral thinking, born of always looking for the easy way out!

The fuel tank can be lowered, without removing wires and original fuel pipe.
Undo 6 bolts holding the 3 tank straps but don’t take out yet. Trolly jack under tank using stout ply between tank & jack.
Bear in mind , my tank is 3/4 full of fuel. I tried siphoning….yes I know you can’t, but I had to try. And I was not going to waste fuel by going on a long drive to deplete the diesel for the hell of it.

Undo the cover of the fuel / adblue fillers, and take out each bolt holding diesel neck and adblue neck. Whilst jack is holding tank up, remove all strap bolts and gradually lower tank, KEEP AN EYE ON THE DIESEL FILLER NECK, AS ITLL NEED EASING PAST ADBLUE FILLER.
Lower tank about 6 inches and support it. Access can now be gained to sender , auxiliary supply.
In order to utilise spigot ( red circled previous photo), rather than hacksaw it off and leaving debris in tank, I heated up a small chisel, and sliced off cleanly the outlet .

If you take it off at the place where it becomes 8mm from the tapered bit , there is a pre drilled hole already there.
Use a short bit of wire bend it 90 degrees and poke it in a short way to confirm.
I then attached a bit of pipe, to see if there was from factory, a pipe from the inside of the sender into the tank, blowing into the tank……I hear bubbles. Saves removal of all the gubbins.

So factory supplied pipe glides nicely over spigot, and I ran that parallel to the existing fuel lines. Incidentally, this new pipe is shaped so it matches contour of tank top.

Anyone thinking of splicing into the existing tank fuel line: DONT. It’s 4 bar!

Tank now replaced, and ready for routing line to heater position….yet to decide.

Thanks, that's great write-up and I'm glad the suggestion of using the OEM pipe worked out well.

Hi, new member. Joined to post this comment.

Just stumbled upon this from a link on the Facebook group. I’m about to do this job and using the original fuel line is a fantastic idea. Does anyone have the part number by any chance?

 

[Pauly]

I can get that for you buddy

 

[rod_vw]

Hi @Jdsurf and welcome aboard.

As far as I can see there are two versions depending on age of the van so as always check with your dealer when ordering.

@Pauly has just come in so I'll let him answer.

There are two factors, vehicle manufacture date and drive type
Vehicle manufactured before or after 15/03/21
PR Codes
1X0 = Front Wheel Drive
1X1 = Four Wheel Drive
1X2 = Rear Wheel Drive
1X3 = Rear Wheel Drive
1x4 = Drive Layout 4x2 (i assume this also refers to rear wheel drive ?)

Base part number is 7C0201361

7C0201361 = not FWD manufactored before 15 Mar 21
7C0201361B = not FWD manufactured after 15 Mar 21
7C0201361A = FWD manufactured before 15 Mar 21
7C0201361C = FWD manufactured after 15 Mar 21

Wow. This is mint. So helpful.

I have a Sept (not sure how to check -logbook?) 2021 MWB 4X4.
Edit. I’ll check the product code. Didn’t see that. Thanks.

 

[Jdsurf]

@Pauly Are you on the Facebook group buddy?

I have a question you might be able to answer that has nothing to do with this part. Would I be able to DM you?
