Yup, another great read from Mr McAleer. Send it on to the British newspapers, Brendan.
Don't know how you telegraphed it before writing it, but I just knew it was the fuel pump as i read on. Or maybe it's memories of 1966 and head-scratching at Scoudouc Raceway - you know, a mechanical fuel pump would have made the MGB a much more reliable car. Like the Volvo of the same era with twin SUs.
