if u have ur original tank from ur halfcut.. u can still use that tank. i reckon it's from 2 door ae92 so it doesn't fit... usually ppl will transplant the injection fuel pump into the carb fuel tank but since welding is done it might rust later on.. i had the same prob with the external fuel pump... but my friend manage to fit the injection tank into my car... just need to modify a bit... it's working in an excellent condition.. no more loud irritating noise from the pump n while taking sharp corners the car doesn't jerk anymore... the last time i went hunting for a injection fuel tank it was bout 500+ in chop shop... even on zth they were selling for bout 600.. hot item ma..
