I have a 1998.5 2500 24 valve. Bought it over the winter and now that it's nice doing some work to it. I have noticed what I'm assuming is the lift pump buzzing continuously on Auxiliary. I cross referenced my issue and all I found was posts about the lift pump running even with the key off, I do not have that issue. One thing on my agenda is to check fuel pressure. However Im most likely going to replace the lift pump anyway. In the bed there is a 30 gallon tank that drains down into the stock fuel tank and I noticed when I bought it that if it had fuel in the bed tank it would leak a bit when you would open the valve to drain the reserve I to the main tank. I've been contemplating getting rid of the tank anyway because I don't ever need 50 gallons of fuel. I guess my question with that is if the system isn't air tight would the lift pump not prime correctly?
