Fuel pipe leak.

#1 Post by badger » Sat Sep 16, 2017 3:54 pm

After sorting my lighting woes I have noticed a fuel leak at the point where the pipe is secured by the clamp on the water pump! I would rather replace the pipe from the fuel pump to the carbs. Looking at where the pipe joins the pump, what type of spanner is used to undo it. It looks like I, may need to use a pair of pliers!! Failing that I could just cut the pipe and instal an inline fuel filter.!

The brass union at the fuel pump end of the metal fuel pipe simply requires a 1/2" open ended spanner!
If you are going to replace the metal fuel pipe, the clip that supports it on the water pump housing requires removing by undoing the long bolt that also retains the water pump housing. That simply needs a 1/2" ring spanner because there is a step in the clip, and an open ended spanner is too big. The long bolt needs removing to open the clip to replace the pipe. There should be a rubber insulator in the clip to prevent the pipe from rubbing, which if missing may well have been the cause of your leak.
I personally would replace the whole pipe in one piece with a good used one. The more joins in a fuel pipe, the more chance you have of a leak!

I'd take the opportunity of re-fashioning a new pipe and routing it futher away fom the engine block and exhaust manifold, using longer clips, to reduce the heat contact and risk of fuel vapourisation.

Unfortunately the nut at the fuel pump end has been butchered before then, as it is almost totally rounded off. Pliers it is then!

I often find with any brass fuel-related nut that it never properly matches any known spanner size. Perhaps there is a special "SU-gauge", not quite the same as but close to the "Solex-gauge". Even after trying some of the rarer SAE sizes, or even metric, the temptation is to just use an adjustable or a plumber's water pump spanner.
That's the way they go.

I'm pretty sure those (brass) nuts are BSF - 3/16" I think. Having an old Landrover means that I have a good selection of BSF/BSW spanners! Useful!

Cheers,
