Hey Scott, That is the Ofna Chackvalve mod that cures the Half Tank Lean Issue. The "pump" as you refer to it, has a chechvalve function that keeps the pressure consistent in the tank. You install it between the exhaust pressure nipple and the tank with the flow (fucntioning direction) towards the tank. That allows the Checkvalve to hold pressure in the tank..
what he said
I was making her rich at the end of the tank or only running the tank half way down untill my LHS got them in stock...4 weeks later.
Just goes to show that TRD is the man with the plan[sm=cool.gif]
