A mate has a merc van, with mech fuel system rather than anything electrical/electronic, a removable screen filter before the main paper filter, with a lift pump down on the engine, the filters being high at the top of the engine.
Anyways the owner changed the paper filter and cleaned the screen filter, and the van refused to start. The AA spent 4 hours looking etc and it still didn't start.
Like a fool, I had a look, paper filter bone dry, and feed pipe appeared ok, bubble heard when he blew down the feed pipe. Engine driven lift pump seemed to work, so "wiggling the old brittle pipes" one broke clean off!!! shit!!!!!
Anyways looking at the broken pipe, and the "break marks and dirt" etc, this pipe must have been "leaking in air" for some time, hence the prior difficulty in starting and dieing on long hills, as very steep hill by the owners house, where he used to park the van. Big clue there as I suspected low fuel or poor lift pump performance, air leak etc.
New pipe purchased and fitted, engine cranked for 30 seconds ( in stages ) and the beast burst into life!
Perhaps a bladder type inline fuel primer should be fitted to the "troublesome in bleeding" bleeding priming systems.
