Another hour was spent on the car on Saturday by the fitment of the copper U pipe I had kicking around for a while as a a bypass to the heater matrix (which is suspected as being blocked). The fuel pipe to fuel filter was disconected and another pipe added which was then fed into the lawn mower fuel can. The battery was also fitted with the vain hope that it would turn the engine over but also to test that the fuel pump was sucking. which it did.
The battery still failed to turn over the engine, but a fire up is getting closer.
