Default Questions about Tanks, Inc with GPA-4 pump

I purchased the Tanks, Inc EFI tank with GPA-4 pump to replace my mallory 140 (which died AGAIN last OCT). This tank appears to be very high quality.. I really like it!

I have configured the pump according to the instructions but it appears to be roughly 1/8" too long and as a result the pump is hitting the bottom of the tank. I contacted Tanks, inc yesterday and they said this "shouldnt" happen and to email them pictures. They havent responded and were not helpful.. at all...

The only solution I see is to remove the pump and cut 3/8" or so off the housing "nipple" for the supply which would allow the pump to move further up once the black tube was trimmed more. Right now the pump inlet is butted up against the nipple on the housing. See the picture with the screwdriver pointing in this spot.. Has anyone else run into this?
