  1. Hey guys i have a 08 mack mp7 that is losing fuel pressure while under load. we have replaced the fuel supply line and all fuel lines on the motor, also injector cups and injectors have been done 3 times in the last 50,000 mi by the dealer. then we did the fuel filter housing and main fuel pump any ideas will be greatly appreiciated. We are sick of the dealer guessing and throwing parts at it and would like to get the truck fixed.

  3. I finally got to drive my B67 a couple days ago ( I still have the grin on my face!) It runs and drives much better than I had anticipated, and I believe the guy I got it from was wrong about the 55 MPH top speed. I got it up to 40-45 MPH, dropped the main box into 5th overdrive (against the dash) and pulled the back box into high range, she dropped down to 12 RPM, in all the years I have been driving, overdrive transmissions do about 3-4 MPH per hundred RPM, this truck is governed to 2100, so that's another 900 RPM, so roughly, another 30 MPH? I'm thinking it will run at least 70! If the little END 673 will pull the gear. Well, onto the engine problem, it has a medium miss when it gets up in the higher RPM's, like over 1500 or so, it doesn't do it idling, and I can't detect it when accelerating till it gets up to around 1500 or so, and higher. This truck had sat for two years, and the guy I got it from got it fired up, and drove it 100 miles to me, over a two hour drive, does this sound like it needs the overhead run? I am new to working on these old Macks, so any help or advice would be great! I have been wanting one for about 20 years though, and now I finally have one! lol. PS, there is NO blue smoke, and very little black smoke from the stack, and I have over 60 lbs oil pressure warmed up. The engine sounds very healthy, other than the miss! Keith
  4. I own a CH613 E7 350 Horse Power Day Cab. I think it is time to change the injectors. How hard is it to remove and replace the injectors? Details on how to preform the work. Thanks
  5. Hello Guys I have a 1980 superliner with a em9-400 v8 engine. This engine has started to smoke black when I am rolling down the road. It idles nice with no smoke ! Last year we rebuilt the injectors and injection pump. I have taken the puff eliminator off......checked the air cleaner.......removed the hose in front of the turbo, which turns easy......checked the air to air.......and checked the suction pipe to the air cleaner. The fuel pressure gage drops from 40 psi down to 18 #s then comes back up.......I do have one leaky injector fitting that I tried to tighten, but is still seeps a little. The manifold pressure gage comes up when more power is required. Any suggestions would be apprecitated. Thanks Byron
