OK so a bit of good news today.
I made a few phone calls to Jeep and Mercedez Benz and got some pricing on the parts drover listed above.
Filter to Pump :
Jeep 05080482AA possibly $50
Pump to fuel rail:
Jeep K05140798AA possibly $120
Filter to Pump :
MB A6650700532 $40.41 + GST (o/night order)
Jeep 05080482AA $44.20 + GST (o/night order)
Pump to fuel
MB A6120703232 $120.48 + GST (see my notes below)
Jeep K05140798AA $115.40 + GST (o/night order)
So apparently Jeep have no listing on any serviceable parts within the hose assembly. Mercedes on the other hand, list O-rings only (clips are listed in the parts diagram but are not available in Aus and according to the guy at Merc, not available at all even if I were to order from o'seas) Now, my note as per the price above is this. The part shown in the Mercedes parts breakdown is a straight through fuel line
whereas the Jeep part has a T-piece connector on it. It is actually a different part number. The Mercedes part number for the correct fuel line
(which I do not have as I did not have a pen on me at the time) has no serviceable items such as o-rings or clips listed (ala Jeep).
So, in a nutshell, I lucked out and found some o-rings off a replacement fuel line
which is not identical to the one on the Jeep but is used in the Mercedes Benz Sprinter vans. The correct fuel line
which suits the Jeep motor was quoted at ~$190+ GST.
Anyway, the o-rings are slightly different in appearance however after checking the Mercedes Fuel
lines to confirm, they are the currently supplied o-rings on the replacement fuel
The O-Ring part # is MB A06019970645 - $3.35 inc GST ea
A quick check on the MB computer systems reveals that basically every MB dealership carries them (one dealer had 60 in stock). I purchased them from Central Star Auto House in Berwick, VIC who had 2 and I bought both, they are expecting more in next week.
Here is a pic showing the old O-ring and the new ones.
Here is 2 pics showing the hose which the O-ring came from, this is the Pump-Injector Hose
Here is a pic showing the broken clip on the hose
Here is a pic showing the cable tie used to close off the broken clip, I know it sounds crude but it is very effective at locking the clip closed and will do the job until I can afford to purchase the full replacement line
Here is a pic of the fuel line
bleeder. The cap is removed and fuel
is sucked out of here. It is a little more complicated than it sounds but has been covered in previous posts and is also in the manual.
