What pump ?

Has anyone doing a V8 EFi conversion on a 110 found an intank pump that goes straight in ? eg range rover etc.

I have now found out that there is one tank in 110 , and that I should be able to fit efi range rover pump into top of tank in blanked of hole that was not used on early 110 . Has anyone got a 110 with an access hatch in rear floor that gives access to this on top of tank , should be later 110 sw If yes could you measure and tell me from each wheel box to edge and from rear door to edge TYIA
