[diesel_mercedes] Diesel Fuel Return Hose 3.2 MM

 

A couple weeks ago I had a leak in the flexible injector return hose , I went to a NAPA Partshaus and the nice man sold me some NAPA # H174 hose  , it seems fine , no leaks and hasn't swelled up and gone soft like some other aftermarket hoses I've tried did .


You might make a note of this P/N or buy 6' of it and stick in the map pocket .


Your original tool kit pliers will easily cut it to length .

[diesel_mercedes] Re: Bypass the servo

 



Yes IF the servo still works and neither stalls out nor slowly grinds to a halt at either end of it's travel .

When you test it , it's critical that the electric motor spins freely then comes to a firm & sudden halt , not slows down until it stops .

late 1970's Dodge trucks use a heater hot water valve that has the correct mis - matched hose nipples and operates via a cable .

I connected the coolant hoses together to bypass the leaky servo.  Of course heat works.

But will the A/C work this way?  Maybe can I just cap the coolant lines?

TIA as always.
