|Stewpot||Thanks to all for information provided. The Gen I engine (mine) does not use the fuel cooler option, so my choices seem to be finding a hydraulic shop to refit new hoses, fabricate replacements as Wookie_Chew_Bacca, Stutz and Lucky Mike have done or track down more expensive (but not out of sight) replacement hoses with the numbers provided by Alydon (and which I have found). I am going to consult with my mechanic who is now recovering, although not yet fully, from his heart attack. Will advise what we do.|

Actually with the fuel cooler there are 3 rubber lines total. One goes from the firewall to the FD from the tank, one from the FD to the cooler, and the 3rd from the cooler to the firewall returning to the tank. There was great discussion on the cooler, it doesn't cool the fuel going to the engine but cools it some before going back to the tank and that's if the A/C is running
First pic is the lines before I changed them right after buying the car, 2nd pic is the new lines plus a 1 inch pipe insulation I installed

|Stutz||Well, when you talk fuellines you really are talking about more than that. If you have the fuel cooler, i think you have two from the fuel unit to the cooler, then two more from the cooler to the lines going to the tank, then of course you have all the lines at the pump. One should not simply replace the fronts and not the fuel pump ones. So when you add all them up and if you buy the from MB its quite expensive. When I did the job I at first used the cohline brand line but afte 1 year saw a little leak. I then went to goodyear fuel injection line and used the rolled clamps. I think all together the cost was like $50.00 with the exception of having to purchase a banjo type fitting line at the pump. Sliding the lines on the barbed fittings were semi tough but not impossible. Good luck with watevr you choose|

I just ordered two sets of Gen I fuel lines for my two AMGs last summer. 126-470-08-75 and 126-470-09-75.

My Gen I hoses are about 18 inches long each and both go to barbed connection on metal lines which then go back through the transmission tunnel (I guess) to the fuel pump(as shown in Bondavi's post #60. Perhaps somebody replaced one of Lucky Mike's metal fuel lines with a long hose?
Alydon, do you have the part number for the Gen 1 hoses? I think they are A1074700165 for the feeder and A1264705264 for the return line, but cannot confirm this. In any case, I can't locate those parts anywhere and I'm told they are no longer available.

|alydon||Why not just buy new hoses from MB? The two Gen II hoses are $162 for the feed line and $61 for the return line. Gen I hoses are $101 and $67, respectively.|

Just be very careful removing the old hose so you don't put even a small nick in the fitting barbs.

humblejoe, yes thank you for this alternative. I know some have used it. Will consult with hydraulic shop in my small town and see what they say, but the option described by Wookie_Chew_Bacca and Lucky Mike seems to work well and I am leaning towards that.
Bondavi..I see your Gen I motor in post#60 looks much like mine. Did you ever finish the repairs and reinstall the engine?

|humblejoe||Why not take old hoses to hydraulic shop to Fab new ones? You can reuse the fittings, and they will have tools to properly crimp the ends|
