Just replace it. You're talking about a car from 1997. If you don't know when the fuel filter was replaced, I'm inclined to believe that it hasn't ever been changed. Very quick Googling shows me that a 323 fuel filter from that timeframe costs less than $20 USD. If you really wanted to assure yourself that it's a problematic filter, you could ...

While disconnecting the fuel pump relay and running the engine will work, there are other alternatives. If you can access the Schräder valve, depress it to release the pressurized fuel before disconnecting the fuel lines. This will have the effect of reducing fuel line pressure. It helps to have the vehicle cool down and not running for a few hours. I ...

I'll preface this with the caveat that I haven't replaced the fuel filter on this specific vehicle before, and my advice is based on experience with other cars. I do think it's good advice regardless. I agree that you should not crimp the lines, but I strongly disagree that you should just disconnect it without depressurizing the lines. Remove the fuse for ...

Other possible sources: Vacuum Leak Other Ignition item (Plug Wires, Distributer, etc.) Really poor fuel Air Filter Blocked Exhaust Blockage I would start with the spark plugs. Take them out and see if they can give any indication as to the true problem. See this answer for more info (While you have them out, replace them if you need to). Then start ...

You are correct in how to do this. I was just watching an episode of "Tech Garage" and they were talking about this very topic. Their suggested methodology was to pull the fuel pump fuse, and run the engine till it stopped on it's own. You can now change out the fuel filter. You will still get some fuel out of the line, but nothing like having 30-60 psi of ...

First thing you need to get some type of penetrating oil. You need something like LiquidWrench,PB Blaster or SeaFoam. My personal favorite is PB Blaster. The second thing you need is patience. If you can, give the penetrant several days to work. I have had goodluck wrapping the fitting in a strip of rag and soaking it with the oil. If you can get the quick ...

The issue of dirty fuel has been greatly mitigated by modern pollution control regulations. Twenty or thirty years ago a lot of underground storage tanks were steel. The steel was prone to rust. The rust would be caused by the water that would settle to the bottom of the tank. The water would be introduced into the tank from the ambient air that goes into ...

I would have to say that it probably isn't worth the effort to pre-filter the fuel. In general, if you're buying fuel with noticeable water in it, then get your fuel somewhere else. The existing fuel filter (providing you're using a good quality one and not a $2 one) should be plenty sufficient to filter small particles etc. The hassle involved in buying ...

This will all depend on the type of fuel pump that your vehicle uses. The stronger the pump, the larger the pressure difference it can manage. If you wanted to calculate a theoretical limit, I guess you could estimate it by calculating the fluid power based on the flow rate your engine requires and the pressure upstream of the fuel filter: Power = Pressure ...

Yes, you can relatively easily determine if your fuel filter is clogged. The XJ600 has a vacuum operated fuel pump below the downdraft carb bank. This is what it looks like. The stock fuel filter is an inline filter and this is what it looks like. As I'm sure you have noticed, the filter is a bit opaque and you can see if it is clogged. It's very easy ...

I have no experience with your model, but sometimes they are located on the petcock, inside the tank. Edit: I cannot find old diagrams, but at least ZZR600's some years younger than yours seem to have had those. Oldest diagram I could find at the moment: http://www.motosport.com/SE/motorcycle/oem-parts/KAWASAKI/2003/ZZR600/FUEL-TANK

Do not crimp the fuel line. As long as you put a rag under the filter, you won't even notice the spray. While the rail may be held at a fairly high pressure, the line is small, so there isn't much fuel in there to escape. On top of that, the fuel line will depressurize into the bottom of the filter and drip down, so you won't have to worry about fuel ...

The black powder was charcoal from the evaporative fuel filter/canister. This filters evaporated fuel from your fuel tank. When your fuel tank gets warmer and the gasses expand above the fuel line they pass through this canister and are filtered out by the charcoal. When the temperature drops a reed valve opens due to the pressure change in other ...

The DPF or Diesel Particulate Filter is part of the exhaust system the Turbocharger pulls it's power from the exhaust system so it in conceivable that a blocked DPF filter could stall the turbocharger causing damage. Also, a failed turbocharger could dump lots of oil into the DPF which would be equally damaging. We have a 2012 1.6 TDI Bluemotion Golf and ...

The fuel filter on your vehicle is part of its fuel pump in the fuel tank. They are designed and made to last the 'life of the vehicle'. They have a plastic OBD2 fuel tank with an interior 'bladder', which means unless something other then normal operation causes damage they never have to be changed.

If it's never been changed, then yes, I'd change it. To get 100k out of a fuel filter is a good life for it. Fuel filters are usually not too expensive, so are a decent maintenance item to take care of. They are also usually fairly easy to change ... usually.

The DPF is basically a catalytic converter for a diesel engine. I wouldn't say it's necessary that both of these things fail at the same time, but it's possible. I will assume you do lots of short trips rather than regular long trips? At any rate, the DPF needs to periodically heat up and stay hot for a long period to burn off excess deposits. A nice long ...

I decided to buy a new fuel filter, and measure after the old filter, and before and after the new filter. I let it idle two minutes before taking each reading. After the old filter, which had been in there for ages, it read 35 psi. Before and after the new filter were both also 35 psi, although the needle on the prefilter reading was jittering a little ...

For the sake of marking this question answered: Sapbucket said "I checked my diagnostic port using Torque and it had only one code: P0868 'low line pressure in the transmission'. I reset the code to see if it would come back again. It hasn't! Nor has my low power issue. So, weirdly enough, this problem solved itself. For example this morning it was 33 ...

Thanks for the replies all. I found it was actually the pump. Whilst it was working the bearings were shot so it wasnt working well. Replaced and all good.

if you have golf mk4 it's located under passages back door even with center of window about 12" in. I have a 3 line fuel filter 2 from tank 1 to engine.make sure you order correct one. the push clips are the trip :)ᙚᵐⁱᒻᵉ ¨̮

There is just one fuel filter. The diagram on this page shows it located off to the side of the fuel tank (it is marked with a 7): http://www.wagenstad.com/index.php?modid=224&page=2-201-40
