560SEL - Fuel line between fuel pumps...

Hi - quick piece of advice I need:

Redoing the fuel delivery on our t '89 560SEL. Put in new check valves, fuel filter, accumulator.

As I disassembled the entire delivery unit, I noticed that the rubber portion of the fuel line between the two fuel pumps was showing some lengthwise cracking on the surface. No way, I though, is this going back in.

So now I found the part here at Pelican Parts. Oops! 152 bucks!

Am I overly worried, or is my airplane ownership experience correct in that I should not, under any circumstances, put the old line back in?

25 year old rubber hose is due for a change. But can't you use some generic hose for less cost?

Does this hose have the "banjo bolt" ends? Most hydraulic line shops can make you a new hose for a fraction of the OEM cost.

It is this guy here in the link:

1989 Mercedes-Benz 560SEL Sedan - Fuel System - Page 1

(fourth item down, pump to pump fuel line)

I love it when people tell me to go to air conditioning shops or hydraulic shops to get something custom done. I live in Washington, D.C., and we have NO such shops around here in the vicinity that I know of (I wish we did). Real estate is too expensive to support something specialized like this, I think. So I think I will need to spring for this part, sadly...

Well........one thing I have learned dealing with a 560SEL is this. Some parts are priced reasonably but pricing on some parts makes you feel like you have been held up by a New York Central Park mugger! FYI, I recently carefully performed a stem to stern inspection of the 1991 560SEL and nowhere did I find a sign or disclosure that said, "This is the world's least expensive ride". As a matter of fact, it appears that 560SELs are definitely going to cost a few more nickels more to operate than a Ford or a Chevrolet.

However, once I get it out on the highway the pain of all those expenses fades away because a 560 drives and rides like no other car on the planet! For the record, I have experienced sticker shock for parts on this car more times than I care to remember. I do feel your pain. But, look at it this way, you won't be replacing that part for at least ten years, so if you cost the price of the part out over ten years it is still fairly inexpensive. It's a great car and will reward you with many years of smooth safe operation when maintained properly.

It's kinda like a friend of mine who travels to europe on business. One time he brought back a $400 bottle of Scotch. He offered me a drink; once my lips touched the glass I knew I could NEVER go back to the cheap stuff......

HuskyMan,

Agree on all points. Overall parts are actually pretty competitive and good on this car, you just once in a while get thumped on something. And I try to go Mercedes and OEM only.

And yes, it is worth it. I rebuilt the front suspension last summer, and will do the rear subframe mounts soon. On the highway. long distance driving, she rules. And they are truly beautiful cars.

So - I sprang for the part of course. No need on skimping...

I thought of one other thing concerning this. Fuel lines are major systems. I forget the exact PSI coming out of those fuel pumps but it is high volume. We don't want to experience a fuel line failure which might result in a fire. I've recently run across several companies who make up hoses for less than dealership OEM prices. Heater and A/C hoses, no problem but fuel hoses are another animal altogether. When it comes to fuel components, only German engineered Mercedes Benz parts are going to get my vote.

Recently, in my locale, a car was rear ended in an accident and caught on fire. I stopped for a moment and gave thanks that at least the fuel tank on a 560 is buried behind the back seat and not slung under the trunk waiting to be punctured by a tailgater.

Only one word: Agreed!
