Hello have a Roosa master injection pump apart that I’m resealing off a 880 I believe and we’re installing it on a 88 I can’t get all of the delivery valve out of the rotor do these old pumps only have two pieces to them (spring and poppet behind Allen screw) or is it that stuck in the rotor thanks.

Under the allen screw is the delivery valve stop, spring, and valve. The valve can be tough to get out sometimes even with the puller tool..

Ok thanks I figured there was one in even these old ones but couldn’t remember. I guess the only thing they left out was the regulator in the transfer pump?

The EARLY Ford four cylinder pumps had no rotor delivery valve. BOTH early and late transfer pump end caps HAVE a pressure regulator, head/rotor assembly will seize without one..

Ok I didn’t see the regulator off to the side I’ve never had one of these that was this old apart before. I have a feeling this delivery valve isn’t going to come out is there somewhere I can order that removal tool thanks.
