Banjo bolt

Hello guys

I've just removed the carbs from my T140E Bonnie of 1979 to check fuel dripping from beneath the float bowl.

First, I thought of replacing banjo bolt and drain plug washers and seal them with Hylomar blue.

I realized in fact that the dripping arose from a loose fuel hose joining the banjo.

I replaced fuel hose on both carbs and it seems to be OK now.

When I put the banjo bolt back in the float bowl, I noticed that there is a hole in the bolt.

Does it matter to align this aperture in the bolt with the banjo port so that the fuel can flow ?

Vertical twins OHV or DOHC, I like them anyway

Hi lilic24000, No you don't need to line up hole in bolt.

Look closely at banjo fitting & you'll notice it's hollowed on inside. That allows fuel to flow from around inside banjo into bolt no matter how bolt hole lines up.

If you do use Hylomar on the banjo washers,it will seal against petrol.I also put some on the threads of the fuel taps.I pretty much seal everything with Hylomar as it has never leaked.Nice and easy to use and washes off easily.

Hi Rambo,

I'm happy with Hylomar jointing compound on banjo bolts and drain plugs.

No more fuel leaks beneath the carbs.

Now I have another problem: no idling after engine start (see new post)
