I am getting ready to order two proform 750 main bodys for my T-ram. Why do they come with 2 extra smaller outer air bleeds for the secondaries. Just curious.
 
What models did you order?
ou
Went I ordered the proform main body to replaced a 3310 vacuum secondary holley i remember getting a extra set of air bleeds.....installed set if you were using the metering place, extra set if you were using the meter block......
 
Only thing I can think of....is it fits 4160 with metering plate and 4150 with meter block.....

one set for the meter plate and one set for the meter block?
 
My proform main body cam with them and had a note in it, that said
change if you have a metering plate instead of a metering Block.
If i remember right it only like 2 number different.
I used the one that were already in it.
