One of the few remaining tasks was to hook up the fuel line from the fuel tank<\/a> to the fuel pump housing<\/a>. This is just a short length AN-6 hose, nothing complicated, but I was not entirely certain that it would actually be possible to get access to tighten the AN fittings.<\/p>\n

After receiving the fitting a few days ago (I don’t know how many times I’ve ordered a fitting that “clearly” is the only remaining one I need for this project, but it’s getting a bit old) it seemed like a nice, easy vacation task for today.<\/p>\n

After mounting the tank in its place, I marked the required length on the hose, cut it, pushed the fittings on and tried it… only to find that it was way<\/em>\u00a0(like 15mm) too short! Oh well, I must not have accounted for curvature or something…<\/p>\n

After carefully cutting the hose to get it off the fittings, I cut a new length, 15mm longer, and tried it. Still about 5mm too short! Finally, I realized the problem: when the hose is pushed on the fittings it’s stretched radially, which shrinks it length-wise. By about 10mm on each side, apparently.<\/p>\n

The third time I knew to add 5mm to the cut<\/em> length of the old one, not the length as mounted, and got something that fit well. 104mm ended up being the magic number.<\/p>\n

This is the fuel supply line going from the fuel pump housing visible on the right to the fitting on the tank (not visible in this view.)<\/p><\/div>\n

I’m also pleased to note that it’s not going to be a problem to get access to the hose. The swiveling fitting on the tank means it’s possible to swing the tank upward and slightly rearward and get access to the fitting.<\/p>\n

The swiveling fitting on the tank attachment lets the hose rotate down when the tank is lifted.<\/p><\/div>\n

Here’s the hose, attached on both ends, with the tank lifted. There’s plenty of access. In fact, I think there’s more room than there was getting to the old fuel hose going to the carburetors.<\/p><\/div>\n

The hose also maintains a nice slope between the tank and the fuel pump, so it doesn’t seem like there’s going to be a problem getting the air out.<\/p>\n

I’m still waiting for one of the AN-4 fittings for making the hose going from the fuel pump to the filter do the 180-degree turn under the seat. Unfortunately it’s not going to get here before the new year, so that’ll have to wait a bit.<\/p>\n","protected":false},"excerpt":{"rendered":"
