Also, I know you’ve mounted it already, but the gasket on the fuel pump plate leaks easily. I had an issue with the gasket leaking.
This is because either the tanks brass bolt threaded sockets sit very slightly proud or, as the tanks plastic is not absolutely flat one or both can mess with the gasket seal not sitting flush. I counter sunk the plates holes on the brass side just enough that the now chamfered holes sit “around” the brass thread sockets rather than on them. This got around the interference that the brass threads were creating.
No leaks ever.
I don’t have pictures, clear as mud?
I often wonder where that road goes? And that, has usually made all the difference. Appologies to Mr Frost
