Hey all! First post for me and hoping yall can help me out. Ive got a fleet of 2021 Mack LR 64 (600) with MP7 engines. We had to drop the tank on a unit for a hole repair and after reinstalling the tank we cannot get the truck primed. We've done the filters, put air to tank and got fuel to the pump. We've used the check valve, ran diagnostics in PTT, we just can't seem to figure it out. Any ideas? Hoping to get some advice on our next direction. Thanks!
