little puppy Posted January 14, 2019 Share Posted January 14, 2019 Hi, have a 2011 pinnacle mp8, it's sucking air and leaking fuel around the plunger shaft ? Can this be rebuilt or do you have to replace the whole filter housing? Does it require anything special to do it? Thanks Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/ Share on other sites More sharing options...
Mackpro Posted January 14, 2019 Share Posted January 14, 2019 Gotta change the whole thing. No special tools really, stubby wrenches help. Just be sure to put the lines and fittings back in the same place. One fitting is actually a check valve and it will also fit in other places and cause problems. The primer pump is replaceable on the newer common rail engine Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413260 Share on other sites More sharing options...
little puppy Posted January 15, 2019 Author Share Posted January 15, 2019 So no way to replace seals in the hand primer? That sucks, about his long sound it take to swap out? Thanks again for the info! Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413271 Share on other sites More sharing options...
fjh Posted January 15, 2019 Share Posted January 15, 2019 Yup they encourage you to pump that bitch 200 pumps after a filter change! Now you know why ! so they can sell you a whole new expensive housing and 3 hours of labor ! oh joy 1 Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413273 Share on other sites More sharing options...
Mackpro Posted January 15, 2019 Share Posted January 15, 2019 On a Friday afternoon at 4:00 , yea I can do one in an hour! Lol. For a first timer , 2-3 hours. The skinner you are the easier it is.

fjh Posted January 15, 2019 Share Posted January 15, 2019 He's heading your way pro!😂 I find it amusing that Cummins can install a nice little ELECTRIC primer pump and no one else has thought to go there! Not a Cummins lover how ever they at least addressed the need to prime and keep the fuel system clean!

Mack Technician Posted January 15, 2019 Share Posted January 15, 2019 Along with the rest of domestic manufacturers like Deere and Cat who install electric primers. Europeans dig cheap, low tech, hand pumps? If Volvo installed an electric primer they might get an extra year of life out of each injector once they start to bubble.

little puppy Posted January 15, 2019 Author Share Posted January 15, 2019 Is there a way to bypass it in a emergency to get back home? 0 Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413343 Share on other sites More sharing options...
Mackpro Posted January 16, 2019 Share Posted January 16, 2019 There are so many passage ways inside the filter stands on the MP engines, it would be hard to bypass the primary side of the fuel filter stand. We talked about changing a fuel filter stand on here yesterday and guess what I had to do today? Yep , filter stand. We have 2 CXN’s , 3 CXP’s and about 18 CXU’s and one Anthem. Had low fuel pressure in one of the CXU’s . There was something going on inside the filter stand. Start to finish a little over 3 hours. Including troubleshooting, r&r filter stand, pressure wash before and after repair and test drive with laptop plugged in . 1 Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413381 Share on other sites More sharing options...

As far as the silicon boots, the shop Forman said ( the tech could best it leaking when he started the truck ) I want to meet the tech that can hear a leak in the air 2 air cooler with the engine running at idle under no pressure?.....

fjh Posted January 20, 2019 Share Posted January 20, 2019 Well if you use Pros flat rate time they roughly charged you 290 bucks an hour to change the filter stand ! nice shop rate ! 😡Wish we could charge that Id be rich! Quite honestly its a shitty job much like everything else on these engines shit in the way,, cramped area to work in. (Cramped areas) We just did an EGR Cooler on an 8 yesterday we tried a different method rather than removing the turbo and stuff we jacked up the front of the engine worked fairly well , saved breaking turbo studs an all the other screw ups that go along with that job ,cut the time by a third or so Worth trying in my mind! 1 1 Quote Link to comment https://www.bigmacktrucks.com/topic/55300-mp8-hand-primer-pump/#findComment-413708 Share on other sites More sharing options...
