Progress Report on Fixing Paddy - Tests 14 & 15

Guys,

Well before moving onto tests 14 and 15, I doubly checked all fuel hoses and clamps, and all where good. Paddy was also due an service so I put on new Oil and Fuel Filters this time went with the more expensive option "Ryco" instead of the slightly cheaper brand REPCO. First morning after service it worked fine, but the next day and each morning after the engine would eventually run rough / lumpy and stall if I did not prime. On the bright side it did not take much priming if I primed early (ie before stall). But at the end of the day, no joy.

So I moved onto Test 14:

Test 14 - Inspecting the Fuel Pickup Line and Gauze Filter

Via the inspection hole in the back of the Pajero I was able to access the fuel inspection cover. After removing 8 x 8mm nuts and pulling the 8mm and 6mm fuel lines off the top, the fuel pickup was easier removed for inspection (Being careful not to damage or break the rubber gasket).

From the following 3 photos you can easily see my tank is clean and the fuel gauze filter was clean and the fuel pickup lines not rusted or have any obvious holes in them to allow air in. I put it back in and bolted down and hooked up the fuel lines and bleed the system. Next Morning the as expected since nothing was really done, the engine ran lumpy and eventually stalled.

Test 15 - Trying a 1 way Value between Fuel Filter and Fuel Injector Pump

After have a chat to a Diesel Specialist, he recommended trying a 1 way value between the Injector Pump and the Fuel Filter. He seemed fairly confident that it would address my issue and if I remember correctly on both UK Pajero Forum, a few thread had mentioned using a 1 way value.

So for $25 I picked up the following 1 way value and installed it and bleed the air out of the fuel lines. Fingers cross, lets see how it goes tomorrow morning.

Cheers
Mark
