Delivery valve sizes

I was looking at my old delivery valves, and found a 131 on the top of the "plunger part". Is this where the size of the delivery valve located?

I think thats the number they use to tell that different ones apart. My OEM valves had 131 on them too. The high performance ones I got from Bosch had 191 stamped on the plunger.

The 215 pumps had 181 delivery valves in them.



Is that what your 215 delivery valves had on them?

Early autos had 131's. Later autos have 151's. 215 pumps have 181's and the cool high flows everyone upgrades to are 191's. Although a used set of 181's is prolly a nice upgrade for one of those automatics.



Were not the early manuals 175hp pumps too. Maybe they had the 131's just like the autos.

I don't know what my 215 valves had on them... I didn't know where to look for the sizes on them. I need to call the guy I got them from to see. I will find out though.
