Find %26amp; fix the leak first. raw gas %26amp; hot engine parts don't mix wellI have bmw 320i 1988 and i want to ask how to know that i need to change the fuel filter?
If you are smelling gas, you have a leak. Check around the injectors after the motor has been running and been driven. You should be able to see a visible means of the leak. I have an 87 Accord that was doing the same thing and I had 2 injector seals leaking. I would check this first. If you don't have any leaks that you see, then start checking the fuel lines and seals around the injection system. That smell is coming from somewhere. This would also account for the performance being off and I bet your mileage is down as well.I have bmw 320i 1988 and i want to ask how to know that i need to change the fuel filter?

When you change the fuel filter look for leaks in the fuel lines.



You might also check the exhaust system to see if the catalytic converter or some other part is clogged. That would also cause low power.I have bmw 320i 1988 and i want to ask how to know that i need to change the fuel filter?
sounds like you have head gasket/intake manifold problem. you may need to change that before you clean the fuel injectors. The reason you have low horsepower is a vacuum leak or compression leak is developed once the gasket composition ibreaks down. There may be a pinch in the gasket which allows air to escape since it's no longer tightly sealed. you can also check for a vacuum hose that's not attached to the proper port. This is also a sign that you need a gasket. The pressure from the intake builds up,seeps out and creates a backdraft of pressure throughout the air compression system of the engine that in turn causes hoses to be 'blown off'. 98.9% chance it's the gasket because you smell fuel AND low compression/horsepower. So, get the gasket changed first then clean the injectors. That should solve the problem.
