: Fuel Filter???

Any ideas as to how many fuel filters there are on the 90 525I and how hard they are to replace...

Just one fuel filter. You can find out more information here. There is a downloadable Haynes Repair Manual that I found online for the E34.

It is near the rear psgr tire. One bolt and 2 hose clamps. Try not to end up smelling like gas.

super easy, FYI clip off one inch of each line going in to the filter, it will save you from a headache later down the road. I just fixed mine, a tear develops from how old the contact point is where the clamp sits. When you cut the ends off you are clamping down a part of the hose that is more fresh. BMW engineers are smart, there is plenty of line for clipping off the ends of the lines. I had a gas leak for weeks and couldnt figure out where the smell was coming from, until I started losing fuel pressure and my car took several tries to start and would idle funny
