O.K.,

This may be a dumb question, but where is the fuel filter on a '90 300SE? Also, when I change the can filter on my 300D, I plan to fill the new one with Red Line. Do I need to pump air out with the hand pump? Previous posts sound like that's a problem.

Thanks,
Mr. BILL

Mr. Bill:

Sorry about the foul-up on my previous post.
The fuel filter on your '90 300SE is in the rear just to the left of your right rear tire. There's a plastic shroud that covers it and the fuel pump. It's accessed more easily if you back the car up on ramps. Both ends have a large nut attached. Slide appropriate
size open end on these nuts, then loosen smaller nut. Some gas will spill out. As for priming, I've never had a problem here. You will have to crank the engine a bit until the fuel get through the system. Also, be sure to pull the ground strap off the battery B4 you begin work.
