Fuel lines route type 4 engine

[AWOL]

Hi folks,

I got a T2b from ‘74 with an 1800cc injection engine and automatic transmission. Great bus and very original. It just wasnt running when I got it as it was stored. Engine turns and all, but it was missing amongst others its fuel pump and fuel lines from the tank to the engine.

Just what is the original, supposed to or best route for the fuel line that goes from the tank to the filter and pump and then to the engine? Any indications or help would be very much appreciated. Pictures of how the line runs even more. Many thanks.

if it is a fuel injection bus it will need a tank with a outlet, and a return line (not a loop someone put in to use a carb tank as a FI tank) You might want to start by verifying that first.

Hi SGKent,

Thanks for your reply. Oh yeah its a FI and has the return line. That one is straight forward to replace and was still there as well.so thats easy to replace.

Its about how the feeding fuel line goes from tank to filter/ pump and engine. As that line wasnt present anymore and I like to let it take the way VW had it designed to run.

is the fuel pump there now? Usually it mounts on the left side rail on two snubbers.

Yeah, there is a new one there now. Just how does the fuel line finds its exact way there from the tank? Or better said, how let VW run it there?

hey awol not sure if the 74 was routed like my 79, but I bent new fuel lines out of quarter inch steel brake line from my flaps...they sold it by the foot... lessons learned?

#1 make sure your fuel pump is wired correctly and pumping the right direction...

#2 leave yourself enough room between hard pipes to pinch the flexible fuel line closed for later fuel filter maintenance and repair....

#3 consider installing fuel cutoff valves...

#4 there was extra padding anywhere the fuel line passed through anything.!

good luck!

my hard lines are too long

my soft lines are too,short...makes it hard to change the fuel filter without a face fullo fuel

green is for go

Interesting. I have never seen a fuel pump mounted in that location. There is lots of heat in that general vicinity as that is where the heat control valves are located.

I have seen them usually a little more forward on the driver's side on a cross member in early bays.

Looks like a new location for later bays like your '79.

EDIT: Just found the answer to my curiousity.

Hi OUR79WESTY,

Thank you for the clear pictures. I did notice the clips under my bus as well that your fuel line uses. Just wasnt sure if they were for the fuel line and how it reached the pump.

The point that BUSBOSS makes is remarkable and coincidence as earlier T2b’s do appear to have the fuel pump on that cross member. So does my ‘74 FI. Later models often seem to have it on this more to the back, as on the picture.

BUSBOSS, What is the exact answer to your curiosity? And how does the fuel line run to your fuel pump on the cross member if I may ask?

I have never seen a California '74 Automatic Bus with FI (the only pre-'75 Bus that came with factory FI by the way) so I don't know 100% for sure - but the fuel line system *probably* looks like a '75. The path of the hose from the filter to the pump inlet is kind of convoluted where it passes through a punched hole in the floor support cross member and loops over the frame to the outside where the pump is located. The outlet line loops over the frame again to get ot the engine. Some early '76's have the pump in this unusual spot as well.

Interesting schematic Scott. That makes it appear that the fuel pump is on the outside of the frame member that travels from front to back which is definitely not correct. The fuel pump on the early bays including early 76 is on a cross member that travels horizontally from driver's side to passenger side. The fuel filter and pump are located approximately near the gray dotted lines below the words "460mm".

I have a 76 with the pump mounted on the outside of the frame as Scott's diagram shows, probably a 75 as well.

My '78 too, same as 79Westy's bus.

This just popped up in Notchboy's 76 panel thread, look closely just forward of the jack point

As far as I know:

'75 - early '76 (VIN unknown) plus '74 CA Automatic (we think?) - fuel pump on the outside of the frame, ahead of rear wheel

mid '76 - fuel pump 'athwartships' on crossmember in front of torsion housing

'77-'79 - fuel pump on inside of frame just aft of rear wheel

There are only two years - '78 and '79 - where the fuel hose layout is identical. Every other year there are small or in some cases large differences in the layout of the fuel hoses.

It is interesting indeed. And to clarify a bit more. My bus is produced in October ‘74 and is a ‘75 model. It has the fuel pump bracket at the cross member. That wouldn’t match with what is being said, year wise. Maybe VW moved them around quite a bit for various reasons.
Like my bus has the aftermarket dpd airco installed and that seems to come a bit in the way of the fuel lines from the fuel pump in its position on the cross member. So it might well be they moved it. It was, as said, all gone so I can only guess.

Hmmm...., interesting point, I wonder if the pump had to be moved on early models because the A/C lines ran down the outer side of the frame.

I've never laid eyes on the sideways one myself, so I can't judge if the mounts were put there by VW, or added later.
