Anyway not sure if they are related. I was going to replace the driver module and the pump and figure on an upgrade while I'm repairing it. Future mods may entail trick flow twisted wedge cylinder head kit so I would rather put a higher flowing pump on case of future mods. Any recommendations on a good brand on a driver module and pump? Any good upgrades? Any input is appreciated !</p></blockquote><p></p>
