this design is out there , its not uncommon  . but not close to the original

over the years i  have found SU get upset by a lumpy idle  ???

you need to measure the output pressure if you can 

unfortunate but many aftermarket pumps have been shown to exceed the 2.5psi max   so buying another may not improv

i take it this is  1300  using a short lever pump and NO plastic spacer

Have ordered a fuel pressure test gauge so I can test the output. I need to establish if it’s too high before I think about a new pump or pressure regulator.

So fuel pressure gauge arrived and I tested the pump - just under 3psi. A little more than the recommended max of 2.5 but would this be enough to cause overflow? As Sod’s law would have it, the carbs are behaving themselves at the moment but likely to play up when least needed such as when waiting at the lights......
