Hi guys thanks for tuning back into the channel on today's episode. We're going to be rebuilding a Makuni fuel pump off a 1998 ski to you formula Z670. This fuel pump actually technically didn't really need to be rebuilt. The issue was there's still a junked up because of the line disintegrating but anyway we tore it apart so we built a kitchen cheap might as well put on new gas. It's on it plus it needs to be cleaned pretty bad as you can see it. This is from like the dirt and old varnished fuel sitting in the here. So this fuel pump is pretty bad. This is like all the junk that came out of it. So all we're going to do this is you're going to need yourself a fuel pump rebuild kit here. This is actually a vertex kit because it's not done as current comes all new screws. Diody frames, gas kits and all that and spring for your pump there. So come to all that new stuff and then if your fuel pump is bad like this or even if it's not I just like can't break clean or carb cleaners just to get it cleaned up there. And for this one we're going to need to brush because this one's pretty bad. Most of them are not this bad they're going to run into but this one is pretty bad so we're going to use brake cleaner and they brush the clean all the stuff up. But first we got to take all of these old gas kits off. Maybe take a picture so you remember how to put them all back together. So that way you put the pump all back together but it's pretty easy. You just put the gas kits like this gas kit you can see there a certain shape. So they're not going to go there they're going to go here and there. So it's pretty easy. I'll just put the gas kit where it lines up so it shouldn't be no issue but nonetheless I'm going to get this all cleaned up here and catch you back. Now to get this cleaned properly you don't want to take the little plastic pieces out here and don't worry about the you have new ones in your kit. So just push them out with like a pick or a little screwdriver. Just pop them out from the back and they'll pop right out. So you don't need those. So for this I recommend that you use rubber gloves especially if you have cuts in your hands like me because it's the brake cleaner, the real thing. It's not a pleasant feeling when that stuff gets in your cuts. So anyway all you're going to do is just spray this down a brake cleaner and clean which is scrubbered out just like you're cleaning anything else so it's cleaning this up. The final stage to cleaning the fuel pump is going to be going through all the passages where the line's hooked up with some compressed air and it's going to go through them all. I went through them with the brake cleaner and got the best I can but some compressed air will be able to clean that completely out. Make sure there's no junk in there still. Now that we got the pump all cleaned up here we can go and put it all back together with all our new gas kits and tire frames and get it back together. The thing that I'm going to do is I'm going to put these little plastic pieces back on there. They go on, there's one on each side and they both go on this side that has a raised raised edge right there so they just go on and then you put your little rubber piece right through them and there you go. So I'm going to put them through. The same technique you took them out but you go through this side. Don't worry about it just so you can get a pick or a little screwdriver. Don't worry about damaging them. You won't damage them most likely. Just push them through until they all pop in and there you go. Now that we got our screwed off setup with our lock washer here and we've got our gas kits all laid out on the order we want. I just like to put the screws like two of them just in here to get these gas kits lined up and then you can start stacking them like so and this will make it really easy to put it all back together. So you're just going to continue stacking the gas kits on the way you had them. So this will make it easy to get back together and then you have your spring there which that's going to hold that diaphragm up there but once you put it all together such as like that and then you can take this part and just line it up with your two screws. Make sure you have this lined up with that so that way your fuel pump is going to work rush you're going to put it all together and realize it's all wrong. So there you go you can see that's all together and then you want to stack your one gas kit right on top of that and see how it lines up with that and you'll want to stack your plastic clear plastic piece on your second gas kit make it also lined up with that and have this this is your cover plate and this has like your your threads so you can tighten the screws up you're going to need a Phillips screwdriver for this and you can see which way this is going so you want to make sure that it gets lined up with that and there you go and now all you need is a Phillips screwdriver tighten this Phillips screwdriver and all we got to do is I'm sure all of you guys now have to tighten Phillips screws up and if you don't know how to tighten the screw up you probably should not be attempting to rebuild a fuel pump so anyway it's as easy as that so I'm just going to put all the rest of the screws in and get you back then. So there you go you can see your fuel pump is all nice and rebuilt there put all new screws on it everything looks nice it's as easy as that don't when you tighten these don't tighten them down like super super tight just want to do them by hand I recommend doing it by hand don't use power tools or whatever if you're going to use power tools as driving until they're snug and then use the final with a screwdriver so the way you can actually test it to see if you've done it right is on these fuel pumps when you blow into this don't blow in it's super hard but you can blow into it and it's you shouldn't be able to have air come out of it so what you got to do is blow into it you don't really have any air coming out and what you can do is you can suck it with your pulse on your pulse thing because this is what the vacuum see suck in and then you should be able to blow for a couple of seconds and you can fuel it the dire for I'm kind of come back up and close your pump back up and there you go you can't blow through it again so that you can pretty much just do that just make sure you can't blow right through the pump and it never closes back up because then you put it together wrong and make sure when you suck in on this pulse it says pee for pulse when you suck in on that you can blow through here and then it'll close back up and that's how you know you have your pump rebuilt right because that's what the engine will do it'll kind of make a vacuum here a little bit and fuel go through and they'll keep making the vacuum and they'll keep pumping your fuel pump as rebuilt and you should be able to rebuild yours now with minimal effort as you can see it's not even that hard so there you go thanks for watching and don't forget to tune in to the next videos for some more interesting content
