Recently installed a ppe lift pump on my lmm.. It started sounding funny, going from a Hugh pitch sound to a low pitch as almost it's running out of fuel to pump. Normal or is it the cold or something

have you put a fuel psi gauge on it and watched for any up down psi changes with the sound ? some have had great luck w the ppe lift pumps several me being one not so good luck
In gonna put a gauge on it.. I put the install kit on it so it starts to pump when the starter engages.. I can't really tell driving down the road but at a idle it defiant fluctuates
