Thats the one good thing about pumps on common rail motors, don't need to be timed !
Ahhhhh but when there's no electric with a common rail tha's ******ed
When I were a snotty nosed apprentice, long retired now but kept the snotty nose, the first job of the day, at this time of year, after getting the kettle on was setting fire to some sump oil and derved soaked rags under the old Diamond T wrecker fuel tank, and yes it had a drop or two of petrol in then with some derv soaked rag on an old toasting fork going round the fuel lines, agglomerator without cracking the glass, another dip in the derv, or sump oil, then stuff it into the air intake then up she fires, couldn't see the garage for an hour or so mind, till the smoke cleared.
Once air pressure was up, next job was a trip round all the brake pipes and reservoirs to make sure there was no ice in them.
Them were the days, no cab heater but a Tilley radiator pumped up near to busting in the cab beats any modern car heater.
Anyway this is nowt to do with Hitch's post so I'll shurrup.
