Probably not a bad idea.
I can't remember if the new pump Roger put in at the Albert Ball was a Walbro or standard and the fuel filter's probably still the original one so will have seen better days.
No need to drain the tanks for either job. The fuel pump comes out the top of the tank and the petrol lines to and from the filter won't be under pressure and can be quickly blocked off when you detach them.
The fuel pump I put in was a standard item, before we knew of Walbro
