  • Fuel pump to support more power

    If anyone has been following my build, I'm well on my way to finally modifying my LX9 for more than factory power. Ported intakes, LX5 throttle body, street/strip cam, headers and full exhaust, and ported heads, and of course a tune. I'm still running an OEM-style replacement fuel pump for the Century's 3.1L engine. I'm sure that it will eventually be unable to keep up with the demands of the added power. What pumps are recommended for that? Less than 300 hp, but more than a stock LX9? And that won't require anything custom, like modifying the sender?

    The walbro 255lph will work. I am not sure when the stock pump would be the limiting factor though.
