wyodog Posted November 25, 2014 Share Posted November 25, 2014 Hey Guys --So I am approaching the end of my truck build, and the truck has not been driven very much over the last 5 years as I have built her back up. I have now gotten to the point of having her around the block a couple of times just to shake things down and a couple of things have come up that I wanted to get some input on. This is my first Mack and so just wanted to throw these questions out to be better safe then broken down...1. The injector jump, right at where the injector lines connect to the pump, very black oil is starting to come out. The engine oil is definitely not as black as what is leaking out, engine oil is actually very clean. I have made sure things are tight and they are. It is only leaking from one of the injector outputs .Is this cause for concern, I sure it is, guess just how big of concern?2. Fuel primer. The manual pump leaks fuel pretty good. Anyone have any suggestion on where to get the rebuilt parts? Or are these manual pumps pretty generic and I can replace it with something else?3. As much as I would love to say I will be driving this truck a ton, I won't. So it will be sitting off and on. I thought it would then be good to add a water separator on the fuel lines. Just thought I would ask to see if we feel this is necessary or a good idea all around?Thank you all in advanced. There is great knowledge in this community!--Josh Quote Link to comment https://www.bigmacktrucks.com/topic/37860-couple-of-end673-questions/ Share on other sites More sharing options...
eddeere Posted November 26, 2014 Share Posted November 26, 2014 I got a new pump from Shel's Supplies & Equipment Co. 203 934 8544 West Haven, CT. $ 22.60 cheaper than a rebuild on the old one. Works ok but the handle is close to the injection pump.

thomastractorsvc Posted November 27, 2014 Share Posted November 27, 2014 I don't have one on mine I just make sure I keep clean fuel and some power clean in it change the fuel filter annually I suppose you could drain the fuel canister if you thought it had water in it.As far as the line that has dark oil perhaps loosening it up and wiping it and re-seating the line might do the trick if you had the lines loose to prime it maybe some gunk got under the threads allowing fuel to seep out and dissolving the crud making it look like oilMy primer pump leaked I took it apart and cleaned it up and put some thread seal er r on it seemed to work although I have not tried to prime it Quote Robert"I reject your reality and substitute my own."
