Hi All,
I seem to have blocked fuel lines from tank . The car runs ok.when I use petrol into carb from jerry can but nothing coming through from fuel tank.
I want to blow out the hard lines but cannot see where I can disconnect and to gain access to tank side end of pipes
. As far as I can tell there is a a connection at tank but just wanted to find out if there are any other joints I can access to check for blockages. Thanks in advance

There should be a large plastic bung in the center of the boot floor. Remove it and you can see the sender with the send and return pipes attached. You could remove these here and try blowing through both with an air line. These are short rubber pipes that join the steel pipes through to the engine bay behind the tank.

All three sets of pipes could be blocked; tank to steel pipes, steel pipes that run under the body and the pipes in the engine bay. You should have some sort of filter along the way too, in the engine bay if you have the mechanical pump.

Thank you so much for the info !
I have a fuel filter fitted at carb but was lost trying to find how to disconnect pipes from underneath.

Hi All,
So today I connected an air line to fuel line in boot where connected to tank and then blew air in to the fuel line. At other end of the fuel hard line in engine bay there was a good flow of air coming through so I cannot see any blockage .
I previously replaced the inline fuel filter at carb fitted but the replacement was bigger than the one I took off. I am getting a small amount of fuel in filter but it is not reaching the carb despite a brand new fuel pump which we have confirmed works.
Could it be that the bigger fuel filter is too big to get sufficient fuel into carb?
Any other thoughts would be welcomed !
Many thanks in advance
Simon

Hi Simon,
The size of filter won't affect the flow.
Have you checked the flow from the tank?  I can't tell whether your tank upflow comes
through the sender unit or from the tank itself. Either way, remove the sender unit, check for
debris inside the tank, and if so, check fuel flow through the sender. A soft plastic/steel gauze is fitted
to the base of the sender.
In the case of the direct from tank feed, there is a non-serviceable gauze mesh inside the
lower part of the visible swirl pot. This will need to be punctured with a home-made right-angled spiky tool.

As suggested, it's the tank area that normally gives problems. 40 year old rust and particles are common.

Thanks for info.
My car is a 2.0 1979 spider if that helps advise on if gauze is in sender or in tank.

Hi

79 carb will normally have mechanical fuel pump and gauze on the pickup in the tank.

Yes first port of call should be lift the sensor/pickup tube assembly in the tank and inspect in there.

Thanks for info.
If the filter is blocked is there a way to replace it with something else?
Any thoughts would be welcomed.
thanks

Simon, yes, mesh filter gauze is available on line.
I would form the shape, wrap it around the pipe and secure with a couple of stainless steel
cable ties.
