There has been some discussion about common rail pumps and how much heat they put into the return fuel.
Sometimes we get called on to hook something to a large and remote fuel tank. It is usually more convenient to use a single fuel pipe for that purpose.
In the old days of A pumps and PFR pumps, some of those could be arranged to return no fuel at all to the tank, or were arranged that way from the factory. Either no return or return back to transfer pump inlet. I guess their normal operation did not heat the fuel all that much that remained in the pump.
With common rail stuff, there has even been discussion that running too small of a fuel tank, fuel tank too empty, or too hot of a climate will cause fuel overheating. Some talk of fuel coolers.
Is there industry guidance on this? (TPG, looking at you) And also how do Stanadyne pumps and equivalent rotary pumps perform with fuel heating of this nature?
