Some of the smaller Lister engines had individual injection pumps (one  
per cylinder) inside the engine casting. With any leak this gradually  
filled the sump to the extent that the engine could  become self  
charging and runaway. The only cure being to suffocate it with a pair  
of engineers heavy duty underpants up the air intake. I'm not sure but  
I suspect the FR injector pump is external to the crankcase.

I was wondering if your sump could be filling with diesel, or even  
water but it sounds like you are safe from both those woes.

You mention the crisp throttle response which, coupled of course with  
the characteristic turbine smoothness, is the hallmark of the green  
motive power units lovingly crafted by countryfolk resident near the  
southernmost escarpment of the Cotswolds.

In former times.
