usernamesarehardtofind Posted January 23, 2016 Share Posted January 23, 2016 Hi, I am new to this site. At work, we have a 90 superliner with a E9, which seems to be lacking in power. We have had it at our local mack dealer a few times already concerning this issue, and they have tweaked a bunch of little things, they say all that is left to do is redo the fuel system, which is what i thought it was in all along. So just the other day i stopped by a local diesel injection shop, and before he was to the truck he had diagnosed it as injectors just from hearing it run. So anyways, we are looking at doing injectors now, and possibly testing the fuel pump while it is all ripped apart. Any ideas or suggestions would be great. Also is there a really good Mack guy to go to in the Kitchener-Waterloo area that is knowledgeable about these old motors?Thanks Matt Quote Link to comment https://www.bigmacktrucks.com/topic/43662-lack-of-power-in-our-e9/ Share on other sites More sharing options...
alex g Posted January 23, 2016 Share Posted January 23, 2016 If your in KW area I think the best diesel pump shop is Sharman in Missisauga. Who do you work for that runs a E9 superliner Sent from my SM-G386W using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/43662-lack-of-power-in-our-e9/#findComment-321119 Share on other sites More sharing options...
usernamesarehardtofind Posted January 23, 2016 Author Share Posted January 23, 2016 I work for Kieswetter Demolition Inc. Our float truck is a superliner. It was the guys at Mike's Diesel that told us injectors.

alex g Posted January 23, 2016 Share Posted January 23, 2016 I talked to one of the kieswetters when he had the green superliner for sale. I have a guy near me in Dunnville that rebuilds injectors if you have them out he could probably rebuild them for you he's retired and does them in his garage at homeSent from my SM-G386W using Tapatalk Quote Link to comment https://www.bigmacktrucks.com/topic/43662-lack-of-power-in-our-e9/#findComment-321126 Share on other sites More sharing options...
