JoeH Posted July 6, 2019 Share Posted July 6, 2019 (edited) Your local Mack dealer sells them. They just might not be smart enough to look them up. Edited July 6, 2019 by JoeH Quote Link to comment Share on other sites More sharing options...

Rob Posted July 6, 2019 Share Posted July 6, 2019 You need to prefill them. 1 Quote Plodding along with no job nor practical application for my existence, but still trying to fix what's broke. Link to comment Share on other sites More sharing options...
JoeH Posted July 7, 2019 Share Posted July 7, 2019 You don't HAVE to, but it makes life harder if you don't. A lot less pumping on a hand pump if they're prefilled. Pump until you hear fuel splashing back in the tank via the return line. Then floor it and crank it til it's running. Ease off the throttle as it smooths out and can idle on its own.

I've always dumped the old filters into a clean jar and after checking for water and none found, dump the contents into the new filters straining through cheese cloth and a funnel. If water is present it goes in the waste oil receiver. Then the tank bottoms get drained. Not prefilling filters sounds like a good way to get "tennis elbow or tendonitis" to me.

diggin dirt Posted July 8, 2019 Author Share Posted July 8, 2019 anyway, i ordered a hand pump, right now i have nothing but a little air pressure in the tank with no luck, scared to put too much pressure. when the pump gets here i am going to try a little air pressure with the pump, if that dont work i am going to fill the primary, if that dont work i will fill the secondary , right now i have no hand pump or any way to prime the system except for air pressure in the tank. thank you guys for responding.
