Robsraptor Posted April 7, 2019 Share Posted April 7, 2019 What is the part number for the injector O-rings on a 1992 EM7? Is there any aftermarket places to get them besides the Mack dealer? Can I just use standard o-rings? Thanks in advance.

JoeH Posted April 7, 2019 Share Posted April 7, 2019 There's a couple materials o rings are made of, some are ok with fuel some are not. I don't recall what material is good for fuel, personally I'd just go to my Mack dealer and get them, but my dealer's parts department is competent. They have no problem looking up parts for my 79 r686st. Doesn't mean every part is still available from Mack, but they are competent enough to look it up and find out.

(Bergey's in Franconia, PA)Thank you for the info. My Mack parts people act like I’m looking for parts for a car from the Flintstones. I think they are too lazy to look it up. I’ll try a different Mack dealer. Quote Link to comment https://www.bigmacktrucks.com/topic/56608-1992-mack-em7-injector-o-ring/#findComment-420100 Share on other sites More sharing options...
JoeH Posted April 8, 2019 Share Posted April 8, 2019 (edited) Shame you're way out in Cali, no idea if Bergeys will ship out to you or not, worth a call! Tell em your dealers incompetent. Fred is the most knowledgeable there. 1-215-822-0402 They'll need your model and the last 6 digits of your VIN.
