The other day I removed the return line check valve from my diesel fuel tank trying to diagnose a fuel dilution problem. There wasn't that much crud in it and the ball would move readily. I removed the hexagonal stand up pipe and tried to blow air through it, but was unable to. Does the the return fuel flow back into to the tank or does the return fuel, under pressure, move the ball and fill the standup pipe only? I have never owned a diesel before so I am on a steep learning curve.
Thanks.

Thank you for the reply. Do you know if there are holes in the pipe for the fuel to flow through or is it just a straight hollow pipe? I didn't see any, but my eyes aren't so good anymore. On mine there was what appeared to be a hard piece of plastic in the end of the pipe. I thought that it might be a screen and flushed the pipe, but didn't get anything out. The plastic piece looked like it was factory so I didn't take it out. Maybe I should remove it so fuel can flow through.

The return fuel from pump opens that check valve and returns fuel to tank. This maintains a small amount of pressure in the pump housing, less than 10psi. That ball can get through that spring and this will cause it to block the flow completely.

Allis Chalmers ED40 - by Anthony West. Allis Chalmers as a tractor manufacturer in its own riht is but a memory. However the number of AC tractors still in existence today as either restored or unrestored examples is a testament to the quality of their products.
