Dropping the fuel tank is rather involved. Beyond this sort of Q&A format.

I suggest you get a Bently Workshop Manual and a seal kit from gowesty.com or similar.

Also plan on replacing fuel hoses and a new filter would be a good idea.

One word of caution. The plastic overflow tanks in each wheel well have nipples for the fuel lines that become quite fragile so BE CAREFUL! The tanks are not available new.

SOURCE: Can I replace the oil cooler seals on 1980 Vanagon w/ engine in?

Hi!
I hate to rub salt in your wounds but after all your effort the time spent you could have the engine back in by now.
All the tin ware needs to be lifted well clear as you know the oil cooler is upright in the path of the Rotor/fan, this also needs to be raised well clear as the cooler needs to be taken off completely, you will want to clean surfaces and internals won't you?
So all shrouds to bodywork off,(Engine bay) throttle cable disconnected, clutch cable disconnected your generator wires off and finally fuel pipe. 4 bolts on gearbox bell housing and slide engine out or down for clearance on trolley jack.
All the above relates to a TypeII Split or bay window with stock engine, Not suitcase or injection.
Good Luck!

SOURCE: I have a T25 Transporter 1990 ,front wipers won`t

It sounds like the park switch inside the wiper motor has failed or a bad contact. If you can get to the motor, remove the plate/cover and you should see a micro switch, check it for broken wires or clean contacts. If you dont feel comfortable doing this, then take the car to an auto electrician, he should be able to sort it.
Hope this helps

Need to obtain 2 pin connector that fits the temp sensor at the thermostat on my vw T25 1.9 water cooled

Try on-line parts store like gowesty.com, van-caf?.com or busdepot.com
Failing that, a junkyard like "pick n pull" or similar is a very good source for items like this.

I have a 1987 vanagon fuel injected gas engine that starts fine, but after 2 minutes it seems to starve for fuel.You can turn the key off and it restarts fine ,but dies again in 2 minutes

A common problem can be the wires to the O2 sensor, and check the connections to the Air Flow Meter. Vanagons are also prone to something called Vanagon Syndrom, which is realted to faulty ground connections. So, check ALL the chassy grounds, by the starter, transmission, battery etc. Disconnect, wire-brush apply di-electric grease and reconnect. Lastly, many of the sensors which feed signals to the ECU could have bad connections, or wires which have breaks or cracks that could lead to corrosion inside the wire increasing resistance. Oh, one more thought, the vaccum lines on Vanagon are covered with cloth and if you pull them off, you can sometimes see cracks in the rubber. The vaccum leaks can also contribute to the problem. Now I would be remiss to not warn you about changing the fuel lines on your nearly 25 year old van. The rubber on these lines have been known to breakdown and leak, leading to engine fires. There is a great web-site called vanagon.com that has all sorts of great informaion on these wonderful vans. I've owned my 84 Vanagon Westy for 23 years. Hope you find this helpful!

1990 VW Cabriolet Gas Smell and humming from gas cap...The smell and sound happens more frequently on warm/hot days. Gas cap seal has been replaced, but still having problems.

The humming noise is coming from the fuel pump.  Its possible its getting ready to fail.  These start making noise when they are going bad.  The smell can be coming from bad gas cap not sealing up fuel tank properly and or a fuel pump/sending unit seal.  You can pull the back seat bottom out easy enough by removing 2 5mm alan screws that secure it to the floor.  Remove the seat bottom buy pulling out and remove black cover under seat bottom that has 3 philips screws.  you may smell fuel more promanently here.

Running rich after warm up.

These vans are now very old, and the gas lines need to be replaced!!! I can't warn you enough, if you smell gas, change the lines. There have been many vanagon fires due to fuel line failure. Replacment kits can be found on-line, it isn't hard to do. The other issues can be related to the fuel tank itself, the seals on top go bad and need to be replace. You know if you have this problem when you fill it to the top and gas leaks.

But, if you haven't changed your fuel lines... do it right away.

Also, go to vanagon.com and look up fuel line and fire... you will see lots of posts!

I've owned my 84 Westy since 87 and changed the lines 5 years ago, many were cracked and leaking. I count my blessings that I didn't have a fire.

1987 VW Vanagon automatic

Look for a vaccum leak, the many vaccum hoses on a Vanagon motor are mostly covered with cloth, if you pull off the hose and look at the end, you may find a crack in the rubber. This leads to air leaks and can cause the timing not to advance properly when you give it gas.

You should also check for fuel leaks, as the old rubber fuel lines can fail and lead to an engine fire. Very common, and if your fuel lines have not be replaced, do it now!

Lots of good information of vanagon.com web-site.

Also, be sure to check to see that your air filter is clean and all the connections around the filter and to your Air Flow Meter are secure. Both electrical and air.
