Itinerant Air-Cooled

I've been poking around for a while and I've noticed a few places make fuel line kits for FI and Single carb engines, but not the dual. Does anyone know of a place that supplies it?
If it's something I have to buy piecemeal, could someone with a bit more knowledge give me the run down of what I need?

I'd like to replace everything while the tank and engine are out.
Thanks muchly!

For carbs all you need is good fuel line. About 10 feet of it will leave you some extra for screw ups. The best I found is Porsche fuel injection line. It's cloth braided, reinforced, German hose so it looks stock and it has a 900 PSI burst rate. Use it for the breather lines too. You can get it at any Porsche/Audi dealership.

If you're like me and you worry too much you can make a steel fuel line with brake line you find at Autozone. Use the rubber hose for the connections.

Hrm..OK.

Does anyone have a diagram to show where all the lines go and such? I've never actually had an engine installed in my bus so I have no basis for comparison.

Thanks much!

Are you using the stock carbs & pump? I assume you pulled the tank yourself and know where those lines go.

Yes, I pulled the tank last weekend and the POR treatment is now curing..

I had solex PDSITs, but I'm upgrading to weber 40 IDFs.

Am I making this more difficult then it needs to be?


Also, where do I get that rubber hose that connects to the filler tube?

Stock pump or electric?

Get the filler hose from German Supply. germansupplyscott is a member here.

You're probably worrying about it more than you should because of the horror stories of burning Bus'. You need to make sure it's done well. But it's really an easy job. I'll take some pics of what I did with mine. I'll be doing it again on my '73. But this time I'll make sure the flapper box doesn't dump heat onto the steel fuel line when the flap is closed.

Electric rotary pump.


I think I need to order some other stuff from Scott too so I'll just order everything and get it done. You're probably right..I'm overly paranoid. It's hard not to be when the fuel lines crumbled under my hands when I removed em..

Mine did too. Plus they were too big. When I touched the line coming out of the tank it fell off and I had a small gas bath.

While you are ordering from Scott you should get a new fuel tank outlet. The ones that come on a Bus are straight. The newer ones have an elbow so it's less likely to slip off. They are pretty inexpensive. Also get a new brass sock.

I also strongly suggest the steel fuel line. Than all you need to worry about is changing the small connections every year.

Fuel Pump Relays. I'm actually only using one now.


Fuel pressure regulator and steel fuel line. The fuel line comes in just below the firewall on the lip. It is out of the way of the engine for installation. When you buy the brake line (to use as fuel line) it will have a union nut on it. Keep the threaded (male) side and find a nut that fits it. Put that in the hole you drill for the fuel line and run the line through it. It will keep the thin sheet metal from cutting through the line.


Steel line under the Bus. Don't use this route unless you aren't using the stock flappers. It will dump the heat on the fuel line. I'll be running it above the tranny then along the tranny/engine support to the same entry shown in the first picture. It may seem like the long way but this keeps any leaks away from the starter and all those live wires.


Cleanable fuel filter and Carter P4070 Fuel Pump. I don't recommend that pump. I've switched to the Redline Weber Rotary Pump. Exactly the same as the one from CB Performance but with a different label. These are mounted just forward of the tank outlet on the slope under the rear seat. You can kind of see the tank outlet at the top of the pic.

Hope this helps.

Wow.

I really wasn't expecting all that detail, but thanks!
I have the weber rotary pump..I seem to recall reading that the pump should be the lowest point of your fuel system. Is that right?



Scott seems to be out of the filler tube hose..is there another source for them?

Thanks again for all the help!

No problem. I like to be thorough.

That is correct. The pump should be as close to just below the tank as close as you can get. It like to push the fuel but not pull it in. I think the area I showed is the best spot.

Scott is the only person I know who sells the hose. Ratwell has a writeup about using a flexible NAPA hose. I tried it and didn't like it at all. I went with the set up from Scott. Have you PM'd him. It may show as OOS but he could be getting them soon.
