Might restrict the amount of fuel getting through and push it up. It'd have to get pretty manky for that though.
I don't have the figures but it's a voltage reading taken at 1000 and 3000 rpm. Only problem with fuel filters is the car won't start if its very blocked!
The Lucas injectors at that mileage are usually dicey. I think the actual reading is arrived at by the injector pulsing( knowing fuel pressure and injector delivery amount) over the distance derived from the abs sensors( new wheels and tires?)

What do you mean by "let by", Johnny?
By let by I mean the injector pulse no longer delivers a crisp waveform. They open slightly before and close slightly after. They also have a very poor spray when they get older. Even at 100000 miles there not great. There not available either. I attribute the Thor's better fuel consumption mostly to using Bosch gen 3 injectors. PS only gen 2 injectors will work with gems(see mark adams site for new and recon) I got mine off an American mustang breakers.

When I got mine (4.6 Thor) in April, the readout stayed around 11-12 mpg. One good long motorway blast and now the 'local' running about reading is 15-16 mpg. It must have adapted in some way (or there were some cobwebs in there). The mpg readout is not 100% accurate: compared with brim-to-brim readings over several hundred miles:
Local: brim-to-brim 16, readout 17.4
Motorway: brim-to-brim 20, readout 22.

My P38 is giving me 11mpg towing a 3.5ton horse trailer,
It is stuck in sports mode making it difficult to lockup in top.
I have had 20mpg solo when auto box was not playing up.
So check the box is in manual mode.
