Don't let it fill your crankcases full of fuel...

I have looked through all my books on 6b models (6b, 6bt, 6bta, 6btaa, 6bta(m))

they all use the same style lift pump, ecept for the VE style pump, CAVS DPA, STANADYNE DB4, AND VP14 pump

It's flow rate is 50.59 gpm at 1800 rpm (this is for rotary)

the only lift pump that I can think everyone is talking about is 3906795, this has a flow rate of 60.74 gpm @ 1250 rpm, this is for 6C motors

does anyone have a part # for this high pressure lift pump for 6bt engines?
You don't want a HP LP 'cause it's going to hurt your FP.
