Hello,

I am trying to determine which in tank electric fuel pump is ideal for a SBF 363 build between 500 and 530 HP. My initial research pointed me toward the Aeromotive Stealth Electric Fuel Pump - 18638. However, I didn't save the link(s) and I'm not sure my reasoning on this unit.

Also - I think I will be running a -6AN line for the supply and the return - let me know if this is a poor decision or if there is a wiser one.


Thoughts, part #'s, etc?


Thank you

Many of us have used the GSS340 Walbro pump, which is 255lph, and would support your HP level. -6AN is also a very popular size.
