Is it the nylon screw on the side of the pump that I need to remove to do this? 65 Chevelle btw.

Hello,

Nice car.

I do not know about nylon screw. My convertable top motors have steel hex-headed screws as the plugs.

The plug is located on the end of the reservoir tank. Not on the sides where the hoses connect.

Hope that helps a little, Joe

Thanks Joe, you are right about the location.
I meant to state that the plugs(s) are on the end of the pump. Theres a HEX head plug center on the end and a NYLON SCREW directly above it. I'm still not sure which one to use to bleed my system. Does the pump itself hold a reserve of fluid? Thanks again.

Yes, they hold a reserve. One half of the setup is a pump and the other half is a fluid reservoir. The pump half has the wires and hoses attached and the other end has a plug at the top. I'll have to look at mine but I thought the fill plug was on top not on the end.

Pretty sure that the center 'hex' holds the resevoir on. The higher "plug" will be the fill/bleed port. On a later model FULL is when the air is out and the top is in the down position, then refit the plug. Not sure on the early models.

ANyone know how best to remove the nylon/rubber plug???
