Differance between Round and Square SMC bottles

[TTA]

I just picked up a SMC square bottle kit used. Is there any difference between the round or square bottle kits? Are the round kits older?

round kits are older and hold more alky. you have the newer one. just make sure pump puts out enough pressure. think its supposed to put out 60 to 80 pounds of pressure. at least thats whay my old kit put up.
