What is part 85?

[Farmboy]

AMT's (I had mistakenly referred to it as Revell previously) 51 Chev kit has the stock and drag 6 cyl engine versions.  I'm decidedly going for the drag option in a street custom but what is part 85?  A  belt drive fuel pump?  An oil pump?

Pretty sure Revell dosen't make a '51 Chevy, Mike.

AMT does with a stock and drag 6 but I don't see any part labelled 85 in the kit??

Ouch.  Call it a loose moment Steve.  Ok, the AMT 51 Chevy, specifically a Round 2.  Instruction sheet page 1, section 1 drag version has the drag engine assembly, step 8 has part 85 (suggest color of "F" (silver) attaching to a super small pulley.  Guess I'll go with fuel pump.
