Sump

[Macbuick]

Hello,

As my engine will be feeded by a Procharger, i have to weld a sump tank and a return line fitting.

Where must i fit the sump ? At the back of the fuel tank (like on a drag racing car), or at the front of the tank?

FRONT of the tank:


or

BACK of the tank:




I was wondering, if welded at the back, during hard decceleration/braking, could the sump get empty and leave the pump without fuel ?



Concerning the return line, i d like to weld the fitting at this place, right or wrong?




Thanks 4 your help
