Fuel Pump? Please advice...
Hello all,
Any help would be greatly appreciated. I live on a hill, I would guestimate the incline to be about 30 degrees? If I park my '95 E300 D facing up, it may take up to 15 minutes to get her started. She cranks but it acts like there's no fuel. If park on the same hill facing down, she has no problem starting. I'm thinking that it maybe that the fuel pump is starting to give signs that it is going south?

Perhaps the fuel is draining back to the tank. or their is an air leak

Do a search - very common symptom when you've got a air getting in the system. Time to be replacing gaskets and O rings and hoses, not the fuel pump. Or just park facing downhill all the time.

Like Len said, the fuel pump is fine, its just working overtime getting rid of air to prime the system when you park nose up.
The most common failed o-ring is the large one beneath the rim of the prefilter (left side of the filter housing if you are facing the engine). Probably time to replace all the o-rings and/or the fuel lines themselves especialy if yellowed.

30 degrees would be a 60% grase. Highly unlikely.

I have replaced the clear fuel lines going into the filter, I'll check to make sure there are no air leaks. Thanks!
P E H - Maybe I just should have said "When park the car on a hill" and not try to figure out the grade of the hill...I guess I'm not too bright when it comes to stuff like that...sorry

I agree, the clear fuel lines and o-rings on 606s like to leak. This can cause fuel to drain back into the tank--particularly the prefilter o-ring--and especially if you park on an incline. Try parking it the other way, if that makes a difference (or the lines are yellow) it's time to replace them.

Curly,
A 100% grade is 45 degrees not straight up. Grade is the tangent of the angle times 100% or about twice the angle in degrees. Anything over 50% grade usually has to be driven by cogs such as a cog railway. Its impossible to go up a 100% grade using a friction drive.

I've been down something like a 140% offroad grade. I survived, BMW didnt.

If a road rises 1 foot over a distance of 100 feet, the gradient is said to be 1% a rise of 2.5feet would be a grade of 2.5%.
Rising 100feet over a distance of 100feet would be a 100% grade. Even the cog railway at Pikes Peak only has a 25% grade on it's steepest climbs.
