Whilst I wait for my son to build my engine waiting for a suitable Crank before we carry on , I have been banished to the fuel system. Tank is now out and so is the 2 gallons of putrid and horrible mixture that has stunk the whole garden out

. I am currently working on the tank. My question is the fuel pump , that is dead as anything and even after a look inside its gone .
I am replacing the fuel line with new pipe 8mm id and will buy a new pump and plumb it in . I cant see the point of the old design pump at £150 when I can get an electronic generic one for £50. As long as its a puller and low psi, is there any reason not to do that ?
Any alternatives or suggestions welcome and thank you
