Z died 40km from home!

[Alfadog]

OK, took the filter off today (finally got time to find a Z92) and cut it open. A picture tells a thousand words...

Tomorrow i will plug on the new filter and report back with the results. Cross your fingers for me!

[Alfadog]

the crud that came out of the filter when I disconnected it.

[Bambikiller240]

If that didn't cause your problem, it should have.

[Alfadog]

thats what i thought!

I took the hose immediately before the filter off, and this is what I found...

I guess I'll have to get the fuel lines flushed out!

Laschlan:

That crap is coming from your gas tank. You are going to need to have the tank removed and boiled out and then repaired. Probably will require sandbalsting the rusted areas and then applying a sealer to the inside of the tank. If the rust is allowed to continue, it will eat holes in your gas tank, and then you'll really be in a difficult situation. The tanks are not available from Nissan and (at least in the US ) are very difficult to find in reasonable condition in salvage yards.

I'm sure that you didn't want to hear this, but that amount of rust in your fuel lines is a sign of significant damage to the inside of your tank and you will be $$$ a head to get it addressed sooner, rather than later.

Sorry to be the bearer of negative news.

I agree you have the worst case of contaminated fuel system I have ever seen in a Zed. It is not unusual for most of that to get pumped into your tank from a bad ( read unscrupulious) petrol station with badly rusted tanks common in QLD. dont write your tank and lines off yet, I recommend flushing lines and tank in the car. then fit new filter and drive for week and then check again. If you can get away from the tank change do so.

good luck

While it IS possible to get contaminated fuel, those pictures show a lot of "contamination". Unless filters at gas stations are non-existant in AU, I suspect that the cause is a rusted 240Z tank. Moisture condenses out of the atmosphere in gas tanks over time. The only way you will know for sure the condition of your tank is to drain the tank and remove the filler hose so that you can look inside. It is not difficult or expensive to remove the tank and flush it. It is more expensive to remove the rust from the inner surfaces and seal the tank if that is needed. You do not want the damage to get too bad. Finding a decent replacement tank when yours is ruined is almost impossible (at least in the USA).

:classic: You can salvage your old tank or at least add years to its use. POR is one co. but there are others that make a coating for fuel tanks . If POR is not available in ozz , try going to a truck building or truck repair shop. They may be able to help you with this , as they fabrecate fuel tanks all the time from sheetmatel and coat the insides to seal them. It is a paint like stuff that is pored into the filler and sloshed all over the inside and the excess is dumped out let to set , and replace the sender and your good to go . I have had a few built for me years ago when dual and triple tanks were not available for pick up trucks and we needed the long range . The stuff will even seal small pin holes in the welds and is safe. Good luck Gary:classic:

POR actually makes a tank salvaging kit which is available over here, comes with flushing agents, cleaners and sealer as well as a small patch for repairing any minor leaks that may occur

[Alfadog]

sjcurtis I dont think all that crud could have come from dodgy fuel stations!! I think a rusted tank is a far more probable cause...

I wonder if he'll drive differently with clean lines?!

[Bambikiller240]

Well, she'll drive, which is different from the current situation!

[sjcurtis]

Do you have any external leaks around the tank area, or is the tank still intact.

I think I should explain, I think you have all missed what I was trying to convey.

I have seen horific fuel tank rust on cars in Australia. ie the fuel tank on the imported C20 chev, it displayed very little in the filter or the hose line rust build up. It just started leaking thru the bottom of the tank thru rust holes.

Just this month a guy in Towoommba had a breakdown on a ford AU 2 Falcon ute with fuel injection failure lots of rust in the line and blocked filter as well. cleaned and flushed the systems came back to normal no more rust in the lines or filter. (AU 2 has a plastic fuel tank).

I was trying to say if a particular gas station has a rusty tank you can get the particals in your tank because we dont have legislation to mandate final filters to the pumps so some operators dont fit them. A cumulitive build up can take a while but if you are a creature of habit the blockage will get there. The average Guy does not chase a fuel fliter on a regular basis, so the first thing you know is bingo my engine is playing up 10 miles later my car stopped. I admit it is not the only possibility but in QLD it is very possible.

Any way, I hope your tank is not rusted.

good luck

Steve.
