Perfect pics there, 👍
I haven't had chance at all to take the top off the other pump to take an post pics, av been flat out all weekend.
Just be careful wen u take it apart that spring don't shoot off somewhere, as said above regarding the Maplin one has an extra prong on it I just snap it off.
Official shurflo ones r £35 I think
Maplin are about £3
Have no doubts about it working mate, u will be back to Maplin next week for a few spares
