[DML] Re: Possible fuel system problem/observation


The fuel pump is built to overdeliver both volume and pressure so that the engine will never starve for fuel, even at high rpm's and full throttle.  The fuel from the return line is exactly as you percieved it, overrun from the accumulator.  Without any backpressure on the line (with an open ended line) the pump will run at max volume capacity which will be more volume than the oriface of the open line can actually pass at a given time so there will be some backup in the accumulator, which will present through the return line.  Not something I'd worry about.

I noticed while pumping the gas out of my tank that some fuel was 
coming out of the return line. I pumped the fuel via the fuel pump to 
the filter and collected it from there. Why would fuel come back 
through the return line? Possibly from the accumulator? If that is 
true than is it possible that my system pressure could be low due to 
this leak into the return line? Or is a little escape through the 
accumulator normal?
