BogMonster Posted January 23, 2008 Share Posted January 23, 2008 Here's a challenge for all you Defender 07MY owners. Especially the ones planning to go around Africa or something. Invent some way of changing a Defender Puma fuel filter which does NOT require a dealer special tool to prime the fuel system (no I am not joking) I think they call it progress....! Guessing they don't plan to sell all that many to 3rd world expeditionary types... Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 23, 2008 Author Share Posted January 23, 2008 FFS and if that wasn't bad enough: "LOW FUEL INDICATION AND RUN DRY STRATEGY The run-dry strategy is used to maintain the systems fuel prime at fuel run out. It ensures the minimum amount of fuel is always left in the swirl pot. The instrument cluster activates the yellow low fuel warning light, (next to the fuel gauge) with 15% of fuel remaining in the tank. The fuel gauge will indicate empty with 11% of fuel left in the tank. With 4 liters left in the tank the run-dry strategy will be invoked. An engine mis-fire will be induced for approximately 1 mile after which the engine will be shut down. The engine can be re-started in mis-fire mode and will continue to run for a further mile until the engine shuts down again. This can be repeated until the fuel suction port in the tank is uncovered and causes engine fuel starvation and loss of prime. Re-starts after run-dry shut down are not recommended. " I love my Tdi Quote Link to comment Share on other sites More sharing options...
disco_al Posted January 23, 2008 Share Posted January 23, 2008 fill the filter with fuel, then restart, surely any air would expel itself? isn't this the transit engine? i will ask someone in the know if they know the know Quote Link to comment Share on other sites More sharing options...
disco_al Posted January 23, 2008 Share Posted January 23, 2008 right, here goes. has your new truck got an inertia fuel switch off switch? if so then the fuel filter housing has a self priming electric pump in the head, if not then invest in a universal primer bulb (vectra's have them, as do some older pug's) and put that into the supply line, problem solved.

BogMonster Posted January 23, 2008 Author Share Posted January 23, 2008 Yeah the "special tool" is basically a primer bulb with the correct fittings on it which goes in the fuel line and you use it to pump the fuel up to the engine, though what then happens when you disconnect it I don't know - maybe there is a non return valve on the line. I can say for sure that it doesn't self-prime, because I heard the swearing... It isn't my truck (thankfully), more of a general comment on the wisdom of the engineering which makes an in-the-field filter change impossible. Definitely an idea from the school of thought that devised electric handbrakes Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted January 23, 2008 Share Posted January 23, 2008 Crikey! that makes Td5's sound pretty basic and un-electronical!! Quote Link to comment Share on other sites More sharing options...

disco_al Posted January 24, 2008 Share Posted January 24, 2008 sounds like the best bet then, get a primer bulb (about £10 from good factors) and install it in line as a permanent fixture. poxhaull vectra's have them permanently installed, as do old 205 diesels.

I have managed the above for F Months with the 80s EFI Lucarse system on my Eales Nige Quote Link to comment Share on other sites More sharing options...
