Others recommend silicone grease on the O ring before jamming the replacement in. Also alternatives to fuel spill issues have been suggested to relieve the pressure and just pull the fuel pump fuse while the engine is idling. Or pull the fuse and start the engine. When it stalls there really may be less fuel in the rail? From all the various methods it seems like the shrader valve method is the designated purpose. The quick change out is obviously key to keeping things next to least disrupted. Cycling the key is helpful. Thanks! I like the attention to getting a good view you provided. Also what not to do by accident like don't loose the cap and bolt!
If there's a way to show you what not to do, I usually find it. Not on purpose unfortunately. The gas itself has lubricating properties, so I've never seen a reason to lube the o-ring. A good one like this has a very light film of lube already on it anyway. You can't really see it but if you rub your finger across it you know something is there.
@@FloydNashFixItDad Ha! On the same page and reading ahead I even tell myself do this or this might happen but I seldom listen to myself. Just did the job and all seems well! Cheers!
From what I find online it should be near the fuel filler neck in the rear right of the car. The filter I believe has the inlet and outlet on the same end of the filter.
I have the same.fuel rail with that style of fuel pressure regulator, however, only after an engine change. There is no connection to the regulator so it is running by another means. Where should I look for another location it's a 2004 S60 2.5T. Thanks!
This isn't actually a regulator, it's a sensor. As I understand, the ECM regulates the fuel pump speed based on the pressure reading. You say you had an engine change? Is that connector present at the end of the fuel rail? Is the sensor present on the end of the rail? If both are there, plug them in. Do you have a check engine code? If so, get to an auto parts store to get use of an ODBII scanner and see what it is. It's possible that with no sensor, your ECM is just pumping fuel at a constant speed so the pressure is actually fluctuating based on how much fuel is bein used. You won't get proper fuel flow at high RPMs that way unless the pump is just running full speed all the time, which can overburden the pump and cause it to fail. AN OBDII scanner will also have the option to read the fuel pressure, so if it's getting a pressure reading from somewhere else, you'll see that when you look it up on the scanner. Check the presence of the sensor and connector, and get a scanner to see what it says.
I do have an OBDII scanner and the code is P0303 misfire in #3 cylinder. I have replaced the coil packs and spark plugs. There is a sensor at the end of the fuel rail but nothing is plugged into it. I will look for the wiring harness that should be plugged into it.
I don't know. A diesel would have a high pressure fuel rail and I don't know what that looks like on the Volvos or what sensor is used. I'm pretty sure it wouldn't be this one.
Not 100% sure, but I think I read on a forum that it can cause stalling or no start. Mine is acting up badly and when I go to step on the gas sometimes, engine power dies for about 2 seconds, then, luckily, engine power returns. Also felt like it would take forever for downshifting to happen and im hoping this will fix all those issues.
I think it depends on which one you have. If you have the 2.5L 5 cylinder or the 3.0L 6 cylinder, then they use standard fuel injection and there would be one of these sensors on the end of the fuel rail. If you have the 2.0L 4 cylinder with the start/stop then it has Direct Injection, which means it has a high pressure fuel pump for the injectors. I believe there is a sensor on the low pressure side, but it's an in-line sensor, not rail mount.
There really isn't a need to. They rarely fail, and when they do the car will still run fine, just with a check engine light. I do highly recommend when a check engine light comes on, find out why immediately. I even have a code scanner in this car, that now belongs to my daughter, and have taught her how to use it.
