tilynb61 Posted July 31, 2012 Share Posted July 31, 2012 Have had the truck a while and am thinking I should change the fuel filter. I don't have a manual but I am assuming it is in the can on the R/H forward side of the engine compartment Anyone know what filter it uses? I don't want to open it up until I have what I need to change it out. Quote Link to comment Share on other sites More sharing options...
randyp Posted July 31, 2012 Share Posted July 31, 2012 Killers is in can in same location and uses a Wix 33090. ABC auto always orders them for me and I keep a coupla on hand. Randyp (61 B-61) Quote Link to comment Share on other sites More sharing options...
Freightrain Posted July 31, 2012 Share Posted July 31, 2012 Like this:I'll agree with Randy, as I'd have to go out and look at my stockpile to see what the part number is I run.Get ready to make a mess, there is a plug in the bottom/side to allow you to drain it. There is a thick cardboard gasket under the top nut when you unscrew it. Remove the top line, then unscrew nut. It's spring loaded, so it will pop up and drool fuel down the sides as the lid come loose.After a couple replacements later, that gasket fell apart and leaked like a siv. I dismantled the fiting and replaced it with something comparable.Clean out the bottom if there is anything. Watch, as my original canister was packed with crud and when I tried to scrape it out, the canister was rusty and I poked a hole in it(DOH!!!). Lucky I was able to get another canister from previous owner that had parts. Thinking back, I should have just removed it. I have a nice separator style filter mounted next to drivers tank to "pre filter" it. Now this canister hardly gets anything in it. Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted July 31, 2012 Share Posted July 31, 2012 yea, mine has long since been removed and the previous owner cobified a holder from the older band clamp and bracket to bolt a new Mack spin on filter housin to. it works and it solid but looks rough, i never changed it but it work and now take the newer style green Mack fuel filter Quote Link to comment Share on other sites More sharing options...

tilynb61 Posted July 31, 2012 Author Share Posted July 31, 2012 Thanks for the help. Gonna tear into it tomorrow. Probably has not been changed for 20 years or more I'm thinking. Quote Link to comment Share on other sites More sharing options...
39 Baby Mack Posted August 1, 2012 Share Posted August 1, 2012 I'm doing this from memory.I'm pretty sure it's a 237GB13 Mack filter which crosses to a Baldwin PF-819Ron Quote Link to comment Share on other sites More sharing options...
randyp Posted August 1, 2012 Share Posted August 1, 2012 Follow Larrys advice and be careful with canister. I usually take plumbing loose and take my whole canister off so i can give it a good cleaning. When re-installing top, push down on spring loaded lid to keep it from turning so you dont cut or split gasket while tightening bolt. randyp Quote Link to comment Share on other sites More sharing options...
Freightrain Posted August 1, 2012 Share Posted August 1, 2012 Oh, ya, forgot about the o-ring. Yup, hold top down firmly and snug the nut down(not too tight, remember that paper gasket).I thought mine was "taken care of" when I bought it. Finally one day it started to not run well and would not hold speed on the highway. I took it home and pulled the filter out. Holey toledo.........it hadn't been changed in a couple centuries. Thus all the crud. Once I chipped the crud out, the bottom had rotted away and the crud was holding it together(and not leaking) LOL!!! Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted August 7, 2012 Share Posted August 7, 2012 usually the fan pulls the salt spray thru in our great northern rustbelt. seen many of B models with those filters rotted out along with the valve covers. Quote Link to comment Share on other sites More sharing options...

tilynb61 Posted August 13, 2012 Author Share Posted August 13, 2012 Thanks for the help from everyone. I got the filter changed, the Wix P/N worked at NAPA. Old one didn't look too bad, housing was in good shape. Quote Link to comment Share on other sites More sharing options...
