大家好,欢迎来到Delphi如何录音系列。我是Deverphi产品和服务解决方案的高级培训师Dave Hobbes。在此视频中,我们将向您展示如何在机库风格燃油泵中更换整个组件。我们始终首先放置安全,所以确保您彻底,您要小心。不要匆忙。不要忘记穿上安全眼镜和手套,手上灭火器,并在距离任何可能具有火焰或火花的通风良好的区域。许多现代车辆已转换为模块化燃料泵组件,但这种风格的2000年中期车辆具有旧式机库风格的燃油泵组件。所以有很多人在那里 - 百万和数百万服务 - 许多都需要更换。所以今天我们将改变机库风格的燃油泵组件 - 整个单元。让我们现在开始。 The electrical connection from the car has been disconnected, of course. The lines, the evap. hoses, the tank has been lowered, been emptied (first drained) and lowered to this steel table where I can catch any kind of liquids, gas, that may still drop there. It may still come out of tank as I do my job. My transmission jack, that I used to lower the gas tank down from the vehicle. Got myself a little drain pan. The old fuel filter is in there and that’s been replaced. So make sure you do that if there is an inline fuel filter. Don’t do a pump job without it. Go ahead and get the pump assembly unit and a new filter while you’re at it. Just think ahead. Now, we want to make sure when we take that last electrical connector off, that the area around the flange is clean. Otherwise debris gets into the tank and we have contaminants in the tank. You may already have that in the tank, but you want to make sure you don’t put any more in there. Alright, so let’s disconnect this electrical connector. What is it? First off, well, it is the fuel vapor pressure sensor for the enhanced evaporative emission system. We’re going to be careful handling this guy. It’s a sensor just like a MAP sensor under the hood. So that last electrical connector? That remains with the tank. It now is part of the pigtail which will be on the new unit. We’ve compared them before we drop the tank to make sure everything looked pretty hunky dory and like we got the right part. And now we’ll make sure we clean around here. I’m not going to need a shop-vac. There actually is vacuum operated shop-vacs that are even safer due to the lack of electric motors and arching of brushes and so forth, than the regular wall powered shop-vacs. Now, normally I get a shop-vac out there and move any kind of debris around the top of the gas tank near the flange so that the debris wouldn’t get inside the tank when I take the sending unit and pump assembly out. In this case, I don’t really need to do that. It’s very clean around here. I’m just kind of using my rag, blow a little bit, nothing comes away. It’s a pretty clean gas tank, mainly because this is a unit that mounts in from the side and not the top. You can see how the top of this tank, where the evap lines are, is filthy. If the sending unit mounted from the top, you definitely want to get a shop-vac out. So electrically we’re disconnected, we’re cleaning around here, and I’ve actually put a little cap that came off the new one on here, because there will be some gas comin’ out. Then I break these loose. First off, with the ratchet attached, and then I’ll just spin this like screws, and go ahead and take the hardware loose.
你也可以做一个备注,这里有一个箭头,如果你没有在坦克本身看一下,那就做一个小标记。我将另一个箭头匹配发送单元/燃料泵组件上的箭头。我们让他们全部放松了。让我们来吧,只是旋转它们,把它们放在桌子上。并且是最后一个......由于它的刺激性而推迟。在我们休息的剩余路上之前,可以在这里快速注意,我确实拥有单位,新单元,开箱即用,我已经读了方向。所以在你有问题之后,不要读取方向。首先阅读方向。我们确保我们根据制造商的规格和方向完成了一切。一切都脱颖而出。 We should be able to, with a little finesse, be able to grab this unit and clear the fuel strainer first, as we carefully prevent any damage or bending to the fuel gauge sending unit arm. I’m going to kind of compress that sock a little bit of that strainer, and as I pull it out very carefully, not bending an arm – too much pressure on it cuz’ I bend that down. If i was to reuse it, we don’t really recommend it but in some cases you do that, you just put the pump in. Only you do want to make sure you do take very good care of your float arm and the the float itself. There’s our unit. There’s our pump. I’ll go ahead and put it over here so we catch any residual drippings from the hanger pump, and grab our new unit and reverse the procedure. Remember where those arrows are lined up and where the fuel line connection was. We’ll go ahead and put the arm in first and kind of compress our strainer unit and slide it on in. Let’s snap on down exactly where it was. Put the screws in and torque them to specs. All right, wait a minute. You know the technician. You have that little voice in your head sometimes says, “Wait, did I forget something?” You know what? Listen to the voice. You want to take a last moment to look at something, sometimes, and make sure you didn’t forget anything. Remember, the directions said, that if there’s a seal, replace that seal. Most of the vapor pressure sensors are in top of the fitting unit assemblies and on the top of the tank. This is the side of the tank, where the liquids going to be. It’s really important not just for a check engine light, but for no fuel leaks, to make sure our seals good. So we didn’t point that out, and as a tech you might not have thought about it, but we’re gonna take a quick peek here and make sure that seal is in place. It’s glued on with the new pump. It might not have been so you want to make sure it’s in place. You make sure it’s clean, and make sure we’re still clean right here, and it looks good. So now you don’t have to have that little voice nagging you all the way back to the tank up into the car as you now start to put things back together and put the fuel in, only to find out that you didn’t do something right – You forgot a seal and it’s leaking. Better do it now while it’s on the bench then have a heartache and have to redo it later. So let’s bend these screws in a little bit of a wrist twist with the ratchet just to cinch it up because we’re going to compress that rubber a little bit. We don’t want to ruin it so we’ll do it in a crisscross pattern. When in doubt, always just do common sense torquing and crisscross patterns so that you don’t create any undue warpage of something flat. Making sure our arrows are still lined up and it feels nice, is seated, because there are little divots in that rubber seal that allow us to put it in position. Sometimes these gas tanks have baffles in them and that’s what makes it difficult to get your sending unit arm and float assembly in place. Along with the the sock or the fuel strainer, like a 10 micron little filter screen. Doing a little bit of the general crisscross here in hand tight and then I’ll just get a little twist of the wrist and give myself a little extra tightness and we’ll be ready to put it back in the vehicle. It probably would be a good idea to put the little red cap that we got off and we put on the old unit back on here so we can keep dirt out of the pump and the tank as we raise her back up on our transmission jack, put it in place, hook up all the lines, hoses, tighten the straps up, and add fuel, and get your customer on the road. We’ll go ahead and make our last little connection. That, you do not want to do while it’s on the vehicle: no room to get your hand up there on top of that tank, so we’ll slide that connector onto that fuel vapor pressure sensor and maybe go ahead and even pop our little wiring harness into place like so, on the side, with a clip, Well, there we go. A complete hanger fuel pump style assembly. We’re ready to go back in the vehicle, add some gas and try it out. Thanks for watching.
