h67st Posted April 29, 2008 Share Posted April 29, 2008 Howdy! Is there anything wrong with putting a spin-on fuel filter base on my 673? I notice there's a bypass line from the canister filter housing to the return line. Is this necessary if I install a spin-on? Thanks very much for your help!

HK Trucking Posted April 29, 2008 Share Posted April 29, 2008 Find a spin on filter base from an early DM or R model with a 673, 675, 711 engine, those had the bleeder line fitting on them and can be hooked up just like your current setup.That way you can also run a Mack OEM filter too, and it'll look like that filter belongs there.

Freightrain Posted April 29, 2008 Share Posted April 29, 2008 On my B, I put a spin on base back behind the drivers tank(right by fittings) and plumbed it in. Even put separator style filter on it to get rid of water. I left the stock unit on motor. Since I put on dual exhaust it really hides it so it's not even noticable, plus I have my big generator box there too. Quote Larry 1959 B61 Liv'n Large......................

95k1500 Posted April 29, 2008 Share Posted April 29, 2008 I used a mack base like HK suggested, had the bleeder and everything. A real easy "bolt on". Works well and again mack parts. Found my base on ebay for about $10 I have a picture in my restoration gallery, you can kind of see it.Dave Quote Link to comment https://www.bigmacktrucks.com/topic/3688-spin-on-fuel-filter/#findComment-18686 Share on other sites More sharing options...
h67st Posted May 5, 2008 Author Share Posted May 5, 2008 I notice you call that extra line a "bleeder line"...is it necessary? I have a standard spin-on base; can I replace the canister type filter with this base?
