Hi,

Quick question regarding the fuel pump on an 83 300D. How dangerous is it to run the fuel down really low in the tank? In my 98 chevy truck I have heard that the fuel pump utilizes a return stream for cooling of the parts of the fuel pump, and thus they give a 5 gallon reserve, so that the fuel light comes on at that amount to protect the fuel pump. I dont knwo how a diesel pump works, so Id liek to know. Does it use a return fuel stream to cool the diesel pump? I have heard that people who let the chevys go way low often have charred wires or burnt out fuel pumps. I dont want to have that happen to any car of mine, so I just want to make sure if it is an issue. Id get gas at 1/4 tank anyhow, but just want to be sure. Thanks

JMH
