My 1974 Plymouth Duster 360

question for you:

i saw that you did an in-tank adaptation of a walbro 255 to an ebay stainless 3/8(?) return style pickup. from the pictures, it looks like you added a support for it. how did you do this, and how did you get the wiring through where it wouldnt leak?

thanks for any help. my holley blue is driving me nuts already.
