Bought a rebuild kit for my 600 DP holley and was looking at the power valve's and stuff and I noticed that it comes with two 65's and one that just has 05 on it does this mean its a 105 or is it just a .5 ? also is it for the primaries or the secondaries....also there are three green pump diaprham things two are the same and one is deeper than the other two scince these kits cover a few different modle's how do I know which on is for my carb?

 

Not sure about the power valve, are you sure you're looking at the identification # and not the date code?

The pump diaphragms are 30cc and 50cc. Most likely you have 30cc accelerator pumps, so you'll use the two shallower diaphragms.

 

pretty sure Im reading it right... has an A with a 5 below it and on the other side it has 0 with a 5 under it...unless they got the numbers on the wrong side or somthing and its a number 55 or is there a 55?

 

There is a 55 (5.5). "A5" is probably Jan 2005.

Are the discharge holes the same as the other two PV's? I'm wondering if the "0" is really a "6". Sometimes those stamped numbers can fool you.

 

justed checked them and the discharge hole's are not the same when side by side with the other ones...if I turn the one in question to match the others it now reads 0 top left A lower left and 5's on the opposite side although there all sideways and the 0 is very distinct.

 

I just bought a kit for the 4779 I picked up. It has 3 PV's, but I haven't looked at them in detail yet. I suspect one is a 2-stage PV, but I've never dealt with them before. I'll try to look at the kit this evening.

 

not sure what my kit covers exactly but they told me it would do my 600 DP so thats all I cared about haha
