1972 c20 402 auto swp pump to carb line?

[6t727t2]

Ordered an inline tube pump to carb fuel line to replace the rubber hose fuel line splice. Inline catalog shows either 71-72 bb 2wd long water pump w/a/c CTC7104 or 71-72 bb 2wd short water pump SCTC7107 which is the one I ordered. When I received it the packing list shows 2wd bb 4bbl short water pump (w/o a/c) 3/8'' line. there was no mention of w/o a/c in the catalog. Has anyone ordered and install an inline tube pump to carb bb 2wd short water pump with a/c, if so which item number did you use? Thanks
