My old ’03 Tourneo Connect 1.8 TDCI with Delphi injection - 5 seater - has been unused for a number of months.
I have never been sure whether it’s a good or bad thing to run and engine for say 10 mins and then turn it off but on the odd occasion when I have needed to it has started sort-of OK - each time needing longer cranking before the engine would fire.
Most recently, after an extra long crank it did start and, maybe stupidly, I did not give the engine a rev’ once the oil pressure came up. I just left it idling and went to move another vehicle. When I came back the engine had died and would not restart.
First I want to rule out an air leak in the fuel line from the tank.

Seems to describe what I need to do to check the lines although it mentions “start the engine” which won’t be happening in my case. From the description I cannot make out which clear plastic pipe one fits to where
Is this particular procedure applicable to Delphi systems? Can I find an illustrated description of the testing process mentioned above? (Youtube maybe)
Am I right in understanding that the fuel (diesel) is ’sucked’ from the tank purely by the high pressure pump? I haven’t located another pump - need I look a bit harder
also
Is there a part no/source for the connectors that go on the to fuel filter? I am thinking of making up a short feed to supply fuel to the filter by gravity from a “canister”. Which is what masterslamma appears to have tried (ie used a canister)
Confirmation of the above notions and any other help or suggestions would be appreciated.
