suejoe6174 Posted August 23, 2013 Share Posted August 23, 2013 I have a B 61 Mack with a 711 engine . It has a primary and secondary fuel filter. Are both of the canisters suppose to contain a filter. The filter on the driver side , the unit metal has type 322 on it--- does this unit contain a mesh element ? If so does anyone know the # or where I could buy the mesh element? Or does this type 322 canister contain a filter? Mine is empty and that doesn't seem to correct.

Superdog Posted August 24, 2013 Share Posted August 24, 2013 If it's what I'm thinking of,that wasn't a replaceable element,just a screen that you took out and cleaned.Damned if I know where you could get a replacement,I'd just do away with it or replace it with a spin on filter if you think you need the 2nd filter.

rsb502 Posted August 24, 2013 Share Posted August 24, 2013 On most old trucks and newer trucks actually the primary filter got the big stuff and protects your lift pump, the secondary gets all the smaller junk the primary leaves behind and protects the injection system. I would have to have something in front of the lift pump, maybe not the mesh but some kind of filter.

countryboy5487 Posted August 24, 2013 Share Posted August 24, 2013 I agree with superdog i would want something before the lift pump to catch the big chunkys. Military trucks have a mesh type of element in their primary filter housing and i would always replace them with a paper filter. Just for a lil piece of mind.

Vladislav Posted August 24, 2013 Share Posted August 24, 2013 My WW2 military Mack has 3 fuel filters.The first one contains brass element with thin slots and a knife in the center.You should turn out a cap nut and turn over a knife axle to scratch dirt off from the filter.The second and the third are common filters of a cardboard type.
