V8 loss of power under load/on hills
I've recently had my v8 110 (1987) serviced, which included a change of fuel pump, replacement of the fuel lines and fuel filter as well as a new air filter. On the shake down run after passing its MOT it has started losing power and slowly coming to a halt when running up any slight incline under load. This did not occur before the service and otherwise drives and runs fine.

To me this would seem to be a full/air problem. My plan is to blow through the fuel lines and see if the problem occurs with the old fuel pump instead of the new one.

Does anyone have any other suggestions? Could there be a timing issue etc?

Thanks in advance!

The fuel restrictor being on the fuel feed line instead of the return line. It's on neither at the moment and runs fine.
