Some Practical Advice on Preventing Charbroiled Busses

by Jerry Brown

As often as we hear stories about VWs burning, or see them on the side of the road smoking, it sometimes seems a wonder there are any Type 2s left on the road at all. It's truly amazing how many ways there are for your beloved bus to catch on fire. Without getting into the really obscure ones, I'll discuss some ways you can prevent your bitchin' sano resto bus from turning into a bitchin' sano resto hunk of charcoal. We'll look at three areas--- fuel lines, carbs, and electrical stuff.

Fuel Lines
You've only heard the warnings about a million times folks. Check your fuel lines regularly. Before doing this I usually run my fuel tank down toward empty, and I keep a couple of golf tees and a bucket to catch any spillage. I also have my fire extinguisher handy. Starting out from the bottom of the fuel tank (see photo), check the rubber fuel hose for signs of deterioration or stiffness. If in doubt, go get a couple of yards (meters for the rest of the world) of appropriately sized fuel hose from your local parts supplier, and just replace the stuff. It's cheap insurance. I use fuel injection line because it's a little tougher stuff, meant to handle more pressure. It costs only a little more. Go ahead and put new hose clamps on there while you're at it.

Start working your way from the fuel tank past the fuel pump towards the carbs, replacing line as you go. Check all the metal sections for holes, crimps, wear, etc. Whereever the line passes through a firewall or bulkhead, pay very close attention (see photo). Bob Hoover has some great advice for making a bulkhead fitting in one of his "sermons", but any way that stops the fuel lines from rubbing against sharp metal edges will work.

Check where your fuel line connects to your carburetor, since this is a common source of leakage. Also check your fuel filter connections for leakage. I personally don't like my fuel filter to be in the engine room, so I have it mounted up in my right rear fender well. It's easier to change, too. The fuel filter is for a Nissan 300ZX, a big, fat metal canister that I have mounted in a bracket so it doesn't flop around. I run a Facet electric fuel pump, and it's mounted up there as well. If I do have to pull the filter, the fuel spills harmlessly on the ground instead of on the engine.

Another place to check that, judging from list traffic and personal experience, rarely gets checked is the short piece of hose on the tank overflow line between the spare tire well and the body (see photo). Every one I've checked so far has been really rotten, and this pup can cause you to burn. I found this quite by accident on my '72, and it seems to affect all the late model busses (loafs) on a full tank. This piece of hose is only about 2.5 inches long. Just stick a new piece on, no clamps are necessary, since there's really no pressure.

I once had a 71 Super Beetle with a Solex 34PICT3 carb on it, and got a really rude surprise one day while working it. I had just put on some new fuel line (following my own advice!), and while tucking it away, the brass hose barb on the carb that the fuel line slides onto came out! This is normally just pressed in there, but it can come loose and spray fuel everywhere. Check yours to make sure it's tight. If not, clean it thoroughly and use a thin coat of JB Weld to keep it in. You can also use some small diameter wire, wrap two or three times tightly around the fuel hose, then attach the other end somewhere on the other side of the carb. This will prevent the hose from popping off even if the barb is loose.

It also goes without saying that the carb itself should be checked from time to time to make sure gaskets or fittings aren't leaking. Not only will you be less likely to burn, but your engine will run better. While you're there spray some carb cleaner on the linkages.

Electrical Fires
These can occur damn near anywhere, and most of them are preventable. When I work on my bus, I check the wiring and hoses in the vicinity of the area. Any frayed wires or bad connections get replaced. It only takes one well placed spark at the right time to ruin your day. Likely areas are the engine room and under the dash. My dash is a tangled mess right now, and it's on my project list to clean up (see photo). I also replaced my stock VW fuses with the Buss-type fuses. Bob Hoover deserves credit for turning me on to that idea as well, he has a sermon on that as well. I'm no electrical genius, and I don't know how to use my multimeter, but I can make a good electrical connection and I can replace a piece of wire. So can you.

Last but not least, check your fire extinguisher regularly. If you don't have one, get one or two, and keep them handy! You can get them on sale pretty regularly. Be sure to get the proper rating. No bus should be without one or two. One of mine is behind my seat, the other is in the back. If you're feeling really fancy, rig up a halon system for the engine room. Then tell us all how you did it.

I'm sure there are about a million other small things you can check or do to prevent a fire in your Type 2. I just wanted to highlight a few ways to not burn. Enjoy!
