Hey guys i need our help! I have an unknown fuel cell ( no name on it anywhere) it is around a 15 gallon, it is black plastic .. Im looking to get a new cap for it ( called jegs and summit they dont have measurements ) but heres my info .. it is a 12 bolt flush mount .. the cap i have now is red in color .. the outer mounting ring diameter is 6 inches the cap is about 3.5 inches with a taper ... if it matters the tank is a bottom sump... so if mine is the same as yours can you tell me what brand it is so i can order a new one !!

Thanks
