very nice tank ! up you did pressure test correct ? i test by making a plate with fitting to attach to the sender unit hole, then seal off all other holes. fill with no more than 10lbs. of shop air and watch for bubbles using soapy water and a gage. when the bubbles stop appearing after i re-do the weld area as needed, and the gage holds 10lbs. for 3 or 4 days, i consider it done. glad you did baffles too. they add strength to the tank as well as slosh control. again, good job !
