The WW2 GMC CCKW pump has a hand primer and metal bowl, it will fit a Chev 216. But looking on-line, rebuild kits are no longer available and NAPA sells a replacement pump . Part No. AC-429 - no hand primer though.
My C8 has the original 216 engine, I fitted a GMC CCKW fuel pump with a hand primer and metal bowl, I bought the CCKW pump NOS many years ago from Auto Surplus in Mitcham . Holden ( local GM car ) Red motor fuel pump kits might fit the earlier GM AC pumps, being AC brand. Side by side , a Holden fuel pump looks to be identical to a older Chev pump.
You need to find kits that are suitable for modern fuel.
New CCKW pump from the Netherlands.
