    What part of the world are you from

    The reason I ask is because when diesel is used in the more tropical parts of the world it grows a moldy slimy residue in the wet season

    There are different fuels to prevent this 

     

    Maybe something to look at

    I'm in the high desert of Wyoming. I'm not saying mold can't grow here, just unlikely.  I treat my bulk fuel with biobor to prevent algae, when I buy it at the pump I don't use any additives.

  2. Got the load dumped by driving 200' at a time. After a longer cool down and it being empty, I would get 400' before it slowing dies.  A buddy pulled me with my F-350 in the low range 3.5 miles to my driveway. Twice I started it to help him up the steep part of hills.  My driveway is a steep grade (26%) and starts at the bottom of another hill. I started the truck, quickly rolled down the hill, turned into my drive faster than normal and made it 1/4 of the way up it. Went and got the D5 (the Ford wasn't gonna pull it up my drive) and started pulling on it. 3/4 of the way up it gets real steep and I started the Mack to help out. Went up, turned it around, parked it in a spot that is easy to work on and let it run (it hadn't quit). It idles for 45 minutes then I shut it off.  I am now convinced that there is something in the fuel tank that is getting sucked into the up pipe.  The combination of a steep angle and bouncing around while turning into the driveway loosened it up and got it out of the way - until next time.

    Winter is back today with 3"-6" in the forecast (I SUPPORT Global Warming!!!) so I don't know when I will be able to drain and clean both tanks. I think the problem is in the passenger side tank as that is the only one that the engine pulls from.  Starting Sunday I am on the road until May 5th.

  3. Went back to the original fuel pump - no change. Checked all fuel hose fittings - no change. Loosened fuel caps and it idled for 10 minutes! Took it for a test drive with the caps off and back to square one.  I am driving 200' at a time. Wait 5 minutes, crank a lot, drive 200' more. I gotta get this load off, no way my F 350 can pull me loaded.

  4. 2 tanks. I replaced the supply lines because it was over due.  After the lines and pump, it ran fine for 4-5000 miles. It couldn't make it up my driveway (26% grade) w/o stalling. 3 sets of fuel filters since then.  I felt around the filter base but did not visually check for o-ring remnants. I will check  vents. Don't think it is a sucking fuel line - if so, wouldn't it have shown up earlier??

    All I can get is 30 seconds out of it (2minutes at idle).  Bosch pump, no manual hand primer.

  5. '91 EM7 starts after a bit of cranking, runs for 2 minutes at idle or  30 seconds if moving, then dies. It seems like it is running out of fuel. If I wait for 10 minutes I get to crank a bit on it, drive it for 30 seconds then it quits again. 

    New supply lines and fuel pump last year. New filters when it started acting up. The return lines were not replaced and I still have the old fuel pump. I replaced the fuel pump, just because I was there doing the lines.

    I'll put the old pump back on, but after that, I'm lost as to what to do next.

  6. I can't compare it to the other ones you listed, as this is the only Mack trans I have experience with.

    You are correct in that it shifts like a Super10, with an additional 2 deep reduction gears. It also has 6 reverse gears and a Neutral position on the shifter(that is what got me in trouble with it). I haven't pulled the dash air switch (for the deep reduction) yet, but it goes with it.  It is a .73 or .78 OD and runs out at about 70mph with 4.42 gears and 11R22.5s

     

    Text first as I don't answer calls that I don't recognize (or leave a message and I'll call back).   303 two04 three 28two

  7. Selling this trans. It has issues!  Check this post to see if you want to tackle the issue.  Otherwise it ran fine until I goofed it up. It has 239K miles on it. It is complete minus the stick (but I have the shifter knob/switches).  I have no idea on the value - throw me an offer.   It is located in Powell, WY and I can ship from Billings, MT 59101.
