So there’s this semilegendary Vanagon guy in Quebec named Ben. He refurbishes Vanagons and VW Busses. He does exquisite work (before, after).
And I love this picture, because my face was under my van just in exactly that position for quite a while not long ago. Except not so smiley.
Earlier today, however, I completed replacing all the fuel lines you can replace without draining the tank. Except for the one behind the firewall on the little plastic connector, which I will get to, maybe when I finally drain the tank and get to the other ones.
Here’s the ‘before’ picture. The cigar-tube of a cylinder in the center is a fuel rail, which is basically a pipe to connect the input hose (here at the bottom of the picture), to the two injectors (the two middle hoses), and the return line at the top. I really should have taken a picture without the spark plug and injector wires.

Note the dust, the grime, and the old injector seals you can’t see here. Flexing the injector hoses yielded a million little tiny gaps. Did they go all the way through? Not today, but maybe tomorrow. Grabbing hold of one of the injector hoses with some pliers to pull it off the injector, it actuall started dripping fuel. That is, it had sponged some fuel up into the hose material itself, and grasping it with the pliers squeezed the fuel out. Very bad. Now, however, all that spongy hose is in the trash. Replaced as on the other side:

The injector assembly is held on by the single bolt you see between the injectors (the two yellow things). Unbolt that bolt, and disconnect the source and return hoses from their junctions, and remove the rail from the engine compartment. Then it’s time to play the cut-hose-to-match-the-old-one-and-clamp-it-on-the-rail game. Not a difficult task at all.
New hose, new clamps, new injector seals, new fuel filter, no leaks. Nowhere near as slick as Ben’s, but still. I’m happy.
