I was under the car the last night putting in some home made Battle Boxes and noticed there is no fuel filter looks like it was just takin off and bypassed. Shouldn't it be on the underside right in front of the gas tank? I couldn't find one anywhere. I noticed when i got the car the guy gave me a few spare parts one was a new filter maybe he planned to change it and couldn't find it either. How can I hook it back up not sure which hose is inlet or outlet?
