When designing a new fuel system plan for a fuel maintenance system. Allow extra piping in the tank to accomodate a seperate suction and return. This simple and inexpensive addition will save you money down the road. the immediate addition of a fuel maintenance system will provide immediate return on investment. For suggestions on fuel maintenance system piping email me and I will help.

when sizing the fuel supply line for the generator, is there a standard diameter to use? or is there a way to get more information on the generator's fuel pump in order to determine losses (friction, valves, bends) and size the diameter from there?

I think you are using a 3516 CAT genset, its power rating 2275 kVA. As for sizing the fuel Supply and Return Lines between the Gensets and the daily fuel tanks, you should take into consideration the MAXIMUM fuel flow rate which equals to 1260 L/H at full load in order to properly size the fuel pipes, Not 454 L/H as for the maximum fuel consumption for the engine, because the fuel goes through the engine not only to supply the fuel but also to cool the injectors then return the rest to the daily fuel tank.
The main parameters should be respected when we disegn the fuel system for the engine, and they are listed as follow :
- The Maximum fuel Flow.
- The Maximum allowable supply line Restriction.
- The Maximum allowable return line Restriction.
- The Maximum allowable Fuel Temperature from the daily fuel tank to the engine.
Please refer to the below parameters for 3516B CAT genset for more details if you need to calculate the effective size of the fuel (Supply and return) Lines :
MAX FUEL FLOW TO TRANSFER PUMP (TO ENG) 1,260.0 L/HR
MAX ALLOW FUEL SUPPLY LINE RESTRICTION 30.0 KPA
MAX ALLOW FUEL TMP FROM TRANSFER PUMP IN 66.0 DEG C
MAX FUEL FLOW TO RETURN LINE (FROM ENG) 1,240.0 L/HR
MAX ALLOW FUEL RETURN LINE RESTR 27.0 KPA
NORMAL FUEL PRESSURE-CLEAN SYSTEM 415.0 KPA
FUEL SYSTEM TYPE EUI
MAX TFR PUMP PRMG LIFT W/O PRMG PUMP 3.7 M FUEL
I hope my information will be helpful and valuable for you,
