fuel hoses..

[mike barrett]

On my TR6 (which I have recently brought) it has, I think, an old style Bosch fuel pump. The outlet is a rubber hose fitted to the pump with a single jubilee click. There are no signs of any leaks and I think it has been like this for some time.

I need to change the fuel hose as its showing signs of failure (surface cracks on the rubber).

So what the best way of fitting the hose, is a jubilee click ok or should I use a crimped clamp or a proper fuel clamp such as

Masterpro hose clip?

 

thanks

They are normally banjo or BSP screwed fittings. If it isn't a problem with the jubilee try that first, its cheapest and least complicated given where you are.

If you're pumping at 110psi should you not have screwed connections?

Crimped after the outlet and also a good idea with the silly rubber return pipe joints from the Mu

I have a Bosch pump, like you I was concerned and sought advice from a specialist in hydraulic, compressed air and fuel pipes and they stated that jubilee clips were adequate at the pressure normaly produced by these type of pumps the vehicle has now done over 30,000 miles with no problems to date.

When I converted to Pi, my supplier's kit of parts was entirely metal, with threaded connectors, pump to Mu. Flexible mesh-covered for the last bit to the Mu.

But bending and threading a single length of metal pipe through all the suspension and chassis parts was rather difficult and I resorted to compression fittings and 8mm pipe from the central heating displays at B&Q. Works fine, no leaks, touch wood.

My car still has it's original rubber pipes from Tank to filter and filter to pump (Lucas) which as you can see is just pushed on without any clips!

Thanks for the comments.

I have ordered some R9 hose and fuel pipe clamps (Master-Pro) so will replace it when it arrives. The Jubilee clamp is secure, it obviously been on the car for some time, but the fuel pipe clamps seem to grip the hose better.
