1984 Honda Magna: Fixing a split auxiliary hose with flex tape

The Magna's fuel system is somewhat complicated. The fuel goes from the main tank to the aux tank, and then to the filter and the carburettors.

BHPian saitvsk23 recently shared this with other enthusiasts.

Spring break is here, and for me, that means I've got more time on my hands to work on the bike!

So from the above schematics (in my previous post), I learned that Hose no.34 is called the auxillary hose, it apparently has the function of letting fuel flow more rapidly into the aux tank, by connecting 2 holes from the aux tank to the main tank. Think of it like a breather hose. The Magna's fuel system is somewhat complicated. The fuel goes from the main tank to the aux tank, and then to the filter and the carburettors. This bike has got 4 cylinders, so that means 4 individual carbs, each one for each cylinder.

So, I got Flex Tape which was specially meant for automotive usage, and just lifted the tank and assessed the slit. I felt it could be completely and tightly sealed using the flex tape. God, the adhesive on the tape itself was so damn strong. I tried cutting the tape using my scissors, but the blade got stuck to the tape and was playing hard to come off. The actual piece of tape was thick, like a 0.1mm thickness of a rubber sheet which is made into tape rolls.

I lifted the fuel tank and put it on the prop rod (yes, the tank has a provision for setting up the prop rod, just like how we have for the hoods of our marutis) and then sealed up the slit using one nice fat piece of the flex tape. And this is how it looked after putting it on:

Now the hose 34 was trying to become a pain by not playing along. It was not sitting in the outlet of the tank. I tried so hard to make it sit, and while looking closely I thought that maybe the clamp was making it tight. And I loosened the hose clamp and slid it back into the picture. Now, it was still feeling tight to sit. Then, I removed the pin that was acting as the hinge for the tank to lift. The tank then came free. Somehow, I managed to make the hose sit somewhat tightly onto the outlet, and then I raised the hose clamp and tightened it to the best of my ability. I still wanted to be sure that the hose wouldn't come off. So I took a piece of the flex tape and put it around the outlet and the hose so that it wouldn't come off. Here's how it looked after I put it on:

Now it remains to see how well my fixes have worked. I'll refuel the tank in a couple of days, and try to start it with some starter fluid. If it works, well and good. If not, it sits for some time, and then off it goes to the dealership for extensive reworking, as either way the bike will need a proper top-to-bottom service to be daily used.

Let's see how that goes!
