Still having problems. Checked the pick up screen and it's clear. Do you still think it's worth dropping the tank? Looked for air leaks and found none. The problem now the Rover will run fine half of the time. It will get up to top speed drive well but then at low speeds or a stop it will run ruff and some times will stall out when I give it gas. It also has become harder to start.
What I have done so far.
New lift pump and filter, blew out the fuel lines, having a oil change done today.
I'm really running out of ideas.
