In-Tank vs. Inline Fuel Pumps

Inline fuel pumps are easier to install than in-tank fuel pumps because the fuel tank does not have to be removed. However, there are several advantages to running an in-tank fuel pump versus an inline fuel pump. FAST™ engineers recommend an in-tank fuel pump when possible.
