Lift Pump Woes...
Have been running a Facet solidstate (like this one)
as a lift pump to fill the swirl pot from the main tank for about 1500-2000 miles but it would appear that the run to Le Mans and back has killed it
(was new at the time of install).
Now the questions I have are…
The pump has been running without any backpressure caused by a carb regulator – is it this type of continuous use that has killed it?
If not, what is the likelihood that if I just stick another one in it will go the same way?
What would be an ideal (cheap) alternative solution?

Try putting a plug in your return tube from the swirl to the tank. Drill a 1~1.5mm hole in it, so that it acts more as a vapour/air breather, than a
fuel return. Should slow down the lifter.
Also, fuel return from the rail should go to the swirl for this to work. And, as I always put...it is good practice to put a small cooler in the
return from the rail, to remove accumulated heat.
Cheers,
Syd.

You're the second person to recommend this. Consider it done.

Yep - return from the rail does go back to the swirl pot

Fixed.
whacked it with a hammer on the bench a few times and it sprang back into action.
Installed a restrictor into the return pipe, too.
Seems to be runnning properly again now...
