My fuel pump is ticking like crazy, on idle it ticks randomly every other second then none then two fast ones, and when I'm driving it some times races, tick tick tick tick tick......tick.... It's very inconsistent. Just rebuilt carburettor and float level is perfect and carb appears to be set up like a dream.
I disconnected fuel pipe from carburettor and put my thumb over the end then turned ignition on, the pump will tick and ones its reached it cut out pressure will stop but does occasional ticks every several seconds.
I only picked up my car last week and it was standing for a few years until I had it and since covered 600 miles in just over a week (the return trip home was 220 miles) and on the way home I noticed the ticking was very irregular and seems to be getting worse.
I know you will find minor issues with cars that have only been used occasionally then used daily, but s it possible that the diaphragm is perishing? I really hope it's not sucking air.
There are no fuel leaks on the car and fuel lines appear in top order.
The pump will pump fuel at a good rate when disconnected from carb, and the car appears to be running fine. But yesterday whilst driving home, the pump was ticking at a good speed which seems inconstant to my driving speed/fuel use.
Any advise will be very much appreciated
