Removing the fuel tank from an R129 is a royal PITA , involving use of crowbars etc , even with everything stripped away ; getting at the pipe connectors underneath involves disconnecting driveshafts from the diff , or even dropping the entire subframe .Hello again guys.
Sorry for the late reply but not been well enough to get under the car until yesterday.
I've drained the fuel out and it looks like varnish & also there was quite allot of debris that came out as well.
Gonna fit another new fuel filter today if I can but just wanted to ask if there's anyway I can clean the fuel tank whilst in situ.
I've seen some posts online that say it can be flushed using water but that sounds a little bit strange to me.
Also I know its probably a silly question but I'm guessing the arrow on the filter points towards the back of the car.
Thanks again guys, you've all been brilliant.
All the best.

I know , I had to replace a leaking tank .
Before taking the tank out , I would look at getting one of those endoscopic inspection cameras , the one below at £80 was the cheapest I turned up on a quick search , but you may be able to hire one from a tool hire shop .
You could pull the fuel strainer out of the tank , which leaves quite a big hole , and put the camera in that way for a look inside .
I’d think , though that if you have drained the tank , flushed through with clean fuel and are not getting any more debris , then it is probably OK . You can flush it through a few times using the same fuel , as long as you strain it through a filter before going back in . Even a paper coffee filter inserted into a funnel should remove any particles big enough to cause trouble . And if you filter the fuel before finally using it , you could run the car on it , so not a total waste . A couple of 20L jerrycans would give you almost half a tank .
