Fuel hose identification.

[CarolinaMBZ]

Replacing the belts on my 82 240D yesterday and accidentally broke the fuel line from the top side/front end of the injector pump at its connection at the other end. The hose is a reddish-brown opaque hose (at least on my car which could mean it was clear when it left Germany). This hose is about 16 inches long and is the other type from the braided black type elsewhere in the engine. There are several lengths of it at other places in the engine bay and all are friction slip connected on barbed metal fittings. Fastlane has several types listed and I would like to replace it with the orginal quality.

Anyone know what I need?

As always, all help appreciated.

Are you guys all such good wrenches that you have never busted a dry rotted fuel line in your car? Help? Seems like someone has been here before, especially trying to torque those heat seized p/s bolts on the backside.

(This was mainly a bump btw).

I'm not sure but I think those are high pressure hoses and need to be of a better quality then low pressure side.

Maybe someone will jump in and tell us what is used.

I use that clear plastic hose from the local lumber yard. Its been used between the fuel pump an fuel filter for the last 3 years. You can see any pesky bubbles. Also good for brake and clutch bleeding in the appropriate sizes. I have been told that is ok for diesel and so far its working fine.

The fuel line he describes seems to be either the fulter - IP fuel delivery line, or the IP return line.
Either of these fuel lines can be replaced either with standard fuel line or clear plastic line.
I have replaced the Filter - IP fuel delivery line, with standard fuel hose, as part of a WVO conversion. It is a bit awkward refitting, due to the hose clamp on the hose, but that is OK too.

Thanks. This is the hose that runs vertically from the pump (on the side of the IP) to the filter mount and terminates into a banjo bolt. Did you guys simply force fit the new hose over the barbed fitting or did you also hose clamp it as well.

Also, FWIW what is there now has block style double numbers running down its length which I had never noticed before (looked again last night). It matches the other lines going to the filter mount.

Thanks again for the info.

I thought those clear IP hoses were pressed on by machine = tight fit. When using standard fuel line on hose barbs, always use hose clamps.

I have replaced several of those LOW pressure lines with the clear plastic and just forced it over the barbed fittings, no leaks yet.

This past weekend, I simply used some hardware store hose and first ran it without any clamps and got no leaks. I then, just to be safe, added hose clamps over the ends. No problems. Interestingly, the hose I removed was extremely thin walled.
