I am a new LR owner. I bought a 1996 Discovery last week. It was a little rough running like there was trash in the pump or filter clogged. I have replaced the air filter, mass air flow sensor, fuel pump (where I found a shop rag in the fuel tank), and I am replacing the fuel filter last. It's rusty and I have gotten the tank side undone but I have having problems accessing the front end of the filter. Can someone give me an idea on the best way to access the filter and be able to get it broke loose due the the rust? I have sprayed pb blaster to help but between wrenches, big hands, and the rustiness I'm at a loss. Thank you.
