This replaces the pump and siphon tube on your late (post 01/1995 build date) E36 323/325/328/M3.
For a track proven solution to fuel starvation in late build date E36’s (1995 and later), this is your answer. With the late style pump and siphon setup, you may begin experiencing fuel starvation as high as a 1/2 tank. With this pump and siphon tube, we have run with the gas light on in a race prepped car on slicks. This is your best, least expensive method of being able to use all of the fuel in the tank. It is also more efficient than dual pump setups, while also putting less heat into the fuel.
