Changing my first fuel filter question

[NSperduto]

I'm getting ready to do my first fuel filter today and the manual is not handy.



MY guess is to drain some fuel out with the drain lever, take the top off the canister, take the old filter out, put the new one in, put lid back on , then cycle the key a couple times to repressurize the system.



Sound ok?



am I missing something?

Here are some things I do



Someone posted up pictures of the filter change a while back. You may want to search the site "Fuel Filter".



I leave the drain open when I unscrew the cannister top. It seems easier (vacuum ?)



You may want to attach an extension to the hose from the

fuel filter cannister, I just bought some clear hose with a male union, I snap it on so the diesel hits my container. Otherwise the fuel dumps on the forward transaxle



Don't forget to remove the old gasket on the cannister top, put some diesel on the new gasket before you put it back on the cannister



It is recommended to wipe out the cannister with a lint free rag. .

You can also wipe the water sensors inside the cannisters...

Many warnings about foreign material in the fuel systems.



Obviously close the dump valve before you fill the filter housing

NSperduto,



I'll second hclark's suggestion about the drain. I did not drain before removing the cap, and got a moderate amount of resistance removing the cap (with filter attached). (Note: Do not open drain with engine running. )



After cleaning around canister, remove filter lid using a socket. (I recall it's 1 1/8 or 1 1/4")



Service manual says to lubricate the O-ring with 30W oil. Diesel sounds good, too.



Torque spec for reinstallation of the canister lid (2003) is 34 N-m (25 ft. lbs. ). Do NOT over-tighten.



Reprime the fuel system per owner's manual after checking drain is closed.



It was a simple job - just wish I'd done it sooner.



Alan.

Emphasize lint free. There are numerous BOLD CAPITOL warnings about the need for cleanliness when dealing with the fuel system in the service manual.

I completely drain my filter housing. Doesn't make sence to leave fuel in there that hasn't gone through the filter. My buddy at international says they completely drain all the Cummins filter housings that are of this type. Then I fill the housing back up before I put the cap back on.

Ok, dumb question, you fill the housing back up with diesel fuel. It's not like I have diesel laying around the house anywhere. and I hadn't planned on keeping any around the house either.

Nick,

Completely drain the cannister, put the new filter in, tighten to 25 ft lbs with a 1 1/8" socket. You prime the filter by "bumping" the starter a couple of times. It will prime itself. Do NOT put unfiltered fuel into the cannister. Piece of cake.

I'm not sure you have to actually bump the starter. I think I just put the key on for a couple cylces. I think the pump starts and runs for like 30 seconds each time. You can hear it run.

Only runs for 2 seconds if you don't bump the starter.

I always have a couple of gallons around for cleaning parts, mostly wheel bearings. It is safer and doesn't smell as much as gas and I don't have the use requirement of a parts cleaner. I have a litle filter setup with a hose that i refill the housing with. Then just bump the starter to get the little bit of air out.
