we're about to replace the fuel pump on a GMT 400 also known as a que 1500 the same between
a 88 to 98 this is on a 5.7 liter Old Faithful 5.7 excuse the wiring just kind of threw things
together first thing you want to do is start your engine let it run and pull the fuel pump
relay which would be sitting right here that's gonna allow the fuel pump to run dry so when you
pull the lines doesn't spray all over your face let's go underneath and start removing it first
thing you want to do is remove the overflow tube and the filler neck tube and leave them connected
to the tank it'll be easier to put back in once you go to put back up and also remember to get
the fuel as low as possible if you're doing it by yourself to make sure that you can lower the
tank and raise it easily let's remove those two clamps next you want to remove the two 15
millimeter strap bolts which I don't know where this oh that one's right there which is part of
the frame assembly it looks like so we'll have to see how that one works but you gotta move to
strap bolts put you a jack under here and let's get it out well the front strap which is here
you must also remove that 15 millimeter bolt and this is like a hold bracket for it and you
got to remove one two three four which would be under the last mount on your side step let's get
those out and away fuel pump all the way down there's definitely enough line an extension up
there you can see it won't aren't off cabling come down I'll go around to the other side show
all right you're a pretty skinny guy you can get in here and there's your fuel pump
so go ahead and pop it out now you have two connectors at the top as you can see
this is already the new style connector for pin clean everything off sometimes the fuel
fill side breaks up there wasn't enough room to get anything in there leading everything
off then you take a flat head screwdriver and knock this ring around counterclockwise and
you should be able to pop everything out after that actually correction nope it's
a snap ring so take that snap ring out and everything should be good after that
Alright snapping removed fuel pump is out then let's take a look down
the tank which is pretty darn clean for its age pretty clean yep looks good if
any one put the fuel pump relay back in cycle I'm trying the engine a few times
fired right up look at and she read imperfect the end
and that's it
