This in-tank fuel pump module can be used to retrofit an internal fuel pump into your rear-mount gas tank. This fuel pump kit features a reservoir tray that eliminates fuel pump starvation that is common on non-baffled tanks. A properly installed internal fuel pump will essentially eliminate any issues that are common on external fuel pumps such as vapor lock and cavitation. Specify 190lph, 255lph or 400lph. Fits 6”-10.5” depth tanks with flat bottoms (60-87 aluminum and 63-72 steel underbed tanks are tapered).
