Good morning from Seward, Alaska...Thanks for joining us today on the vlog...We are
here to do a fuel filter change on Denny the Expedition Vehicle!... Yep! So we have a
2007 Mitsubishi Fuso FG140...It's a commercial medium duty
work truck but we use it as a 4x4 RV! We have the 4M50 engine and fuel filter...
Very critical maintenance on these diesels guys! It's not one to overlook!
Well before we get started on the fuel filter... We want to remember to tell you to check
out our website www.HisandHersHub.com. A fantastic resource for the traveler! We have access to our videos but we also have courses, both free and paid...
Ebooks, Ezines, Forums...All kinds of fantastic things for you to interact in and so head on over there check it out, become a member! Since these are very much work trucks
and customized to applications... I can't say that your fuel filter ball is going
to be in the same place as ours...But this is one of our 30-gallon fuel tanks. We
have a tank selector valve for side by side but the fuel filter bowl is right
here!...Well now off the bottom of the fuel filter is a sensor...I'm gonna just take a
shot in the dark that there would probably be like a water and fuel sensor but...Undo
the harness connector that leads to it. It'll save you a lot of time and today
it actually probably didn't... Because this was a royal pain in the butt to get off
because we had Dempster Highway mud...It kind of dried into the tabs...But now we are
going to drain the bottom of the float or a fuel bowl to see if there's any
water in there!... Well, you can see we had some water in our fuel...And then I was
talking about that Dempster Highway mud... Man! That stuff is everywhere and it's
gonna be a long time cleaning it out!... The truck came with this nifty little wrench
for the fuel filter and it just...Slides right over...Another reason why you need to
move that harness...But it is rather tedious here! It does not turn very far
given the space restrictions that we have...And it is mighty snug! So it's a little
pull as you go! Suckers tighten this... Dempster dirt!... I
think we're gonna be saying that for a lot of years!... Yes, definitely!... Well this is the home
stretch... I don't know how yours is gonna be but
this one is...Needless to say, tight! Okay, there we go...There it is! There's a little bit of
water down in the bottom of that!...They definitely, do not mix well!... There's some
carbon choke throttle body cleaner...You want this to be nice and clean before
you...Put it all back together...Then I'm also gonna just hit these threads real quick
on the outside...Okay, now let's pull the filter off...Ahh yeah...That's definitely
dirty guys! The filter comes with O-rings for this bottom piece...And also a new
O-ring for the main bowl...Okay, it always helps to put diesel back into the fuel
filter...No it's not vodka!... Sure it's not flavored vodka!... Yeah, exactly! It's that design of vodka.
And then we just kind of put this bowl back up there...And slowly thread it on! I'll do
as much of my hands first, there we go! You always add the fuel to the bowl, just
so you don't have to reprime all that fuel into the system! It is possible to
do it without...It's just a heck of a lot easier to dump some fuel in!... Alright, one last snug...
It's on there all the way...This is the other end of that wire off the bottom of
the filter bowl...There's a connector back here...Just plug it on in! The lighting's
not too hot! But on the top here there's a spring-loaded button and you just kind
of... Push it and you can...Prime things. I really don't think we need to do that
too much. It should take care of itself when we start the engine because we did not
lose much from the lines...And we refilled the filter bowl! Let's get this engine
started to make sure we are having air in the lines...
Now, time will tell!... I guess it's kind of good that this is happening because I
get to show you the process...But there's two bleeders on the top of this filter
housing and there's no way of getting the camera in there! You can't miss them! Ten
millimeter wrench...You just crack them open like you do bleeding brakes and
pump the top... I think we're good! Alright, hit it Beck...Alright, let's give
it a few minutes and see if it stalls out but I think we're good!... Okay the
engine has been idling for about seven minutes now...So we are in the clear for
another 15,000 miles as long as we don't have any corruption of our
fuel system...Thanks for joining us today!... Be sure to hit that SUBSCRIBE button so
can see where we're headed in those miles!... Yeah, we don't always just work on
this thing, we do travel in it and there's good things ahead! We'll see you on the road...Bye, bye!
