If you have the correct dimensions it would be helpful if you would post them along with a pic. |

Follow the hatch latch post back, and from that rib, go two ribs to the right (one rib over works, two makes more room) and cut about 4 inches from the drop off behind the seat toward the hatch. 3 sides of the square you cut, fold the fourth..
Just did this last night to my 72...i feel guilty i hacked such a rust free bus, but i need that sender out! _________________ Stuart Zickefoose

That is weird. The engine cover in the picture looks like an early one 68-71. Unless they used an old picture.

How much was it off?

800mm from the left and 880mm from the hatch will put the hole smack dab in the middle of the sending unit _________________ 'Black Ice'Drag Buggy 'Turbo'

That sounds to be almost exactly what the VW instructions say, only about 1/4" off on the center of the hole, right to left. |

FWIW I changed out my sender today without cutting an access hole and without pulling the tank. I did have the engine out but I could have done it easily without doing so (well, not as easy, but easy enough).
Just pull the firewall, take the vent tubes out of the way (change your rubber lines, mine practically crumbled into dust), then use a suitable tool and a mallet to tap tap tap the sender around. You can angle it around the forward LH side of the bus and out.
Hope my crappy aftermarket sender holds up. I did test it but the quality seems suspect. I can see how an access hole would be great if you had to do this all the time but if it's just a once every 5-10 year sort of thing it seems like more work to cut the hole. _________________ 1977 Westy, Automatic.

Probably you're right but I don't know what else to do. I held onto my old one and maybe some winter evening I'll try repairing it with new wire according to that post somebody made. I wish there was an easy way to adapt an aircraft capacitive sender, no moving parts. But they output 0-5v which is incompatible with the VW gauge. _________________ 1977 Westy, Automatic.

I just replaced an aftermarket sender a couple months ago that looked really new. I installed an original VDO sender that had the Telford Repair done to it. That baby will last decades. _________________ Lead Mechanic: San Diego Air and Space Museum

I have an old 73 412 I keep for spares, as I have another 412, and am currently stripping the interior from my 76 Bay, and having the fuel gauge only registering the top 16 litres of fuel from full to empty, I believe I need to adjust the arm on my existing fuel sender to register the full tank from full to empty.
So I'm looking to fit one of these access panels.
I mentioned the 412 because in the load floor behind the rear seat is an access panel for the Eberspacher, and this looks identical to the one shown in the early illustration / pictures.
I think I'll be buying a new fuel sender for the Bay, and removing this 412 panel on the spares car, to see whether I'm right.
With the VW parts bin used as it was, I bet I'm right. _________________ 73 de M5WJF

people also happen, ignore the cut in the tank, this bay tank had 5 screw holes in it, from a PO who fitted a home made interior, i guess they only had looooong screws

This picture reminds me of one of my local acquaintances, who installed a second-hand campervan interior into his 1973~79 VW "1700" Type 2 Kombi.
Either through ignorance or stupidity, he ended up drilling five holes in his fuel tank which resulted in a smell of petrol, of which he could not isolate the source, until I starting interrogating him.
Ultimately I supplied him with a second-hand 1974 VW 1800 Type 2 fuel tank I had spare, and took his perforated fuel tank in part exchange, which I later had repair-welded by another of my acquaintances, who many years earlier had repair-welded my corrosion-damaged Triumph Toledo (an amazing car, not sold in North America!) fuel tank. _________________ Regards.

Got to ask,how often does the sender need service,I have owned probably 30 cars over the years,and only 1 or 2 times have I had to service a fuel sender.I have never cut a hole in a trunk or the box of a truck the get at it,don't think I would do it to the bus,also it may be a fire hazard unless the hole is well sealed. _________________ https://www.thesamba.com/vw/forum/viewtopic.php?t=620186

I think I'm going to do it to my bus and here's why. The PO of my bus did an amazing job restoring the tank, engine compartment, and installing the engine. It's a work of art. The thing is that he must have installed an aftermarket fuel sender while doing the work and it's been in there for a few years. Now it's taken a shit. I have an original VDO sender that I want to install that's been repaired by Telford Dorr. So, do I want to pull the tank or cut a hole? I'm going with the logic that says VW would have installed an access hole if they could have but decided to keep things cheap and simple. I have donor metal to make the door. When i'm done I'm hoping that the access hole will look factory. I've done this a couple times so I know pretty well where to cut the hole. _________________ Lead Mechanic: San Diego Air and Space Museum
