Old Pro-Lite run on HPA?

Using a 4500 tank won't increase the velocity.  The numbers 3000 and 4500 refer to tank capacity, not output pressure.  Related to this, I would start by checking the output pressure of the tank you are using.  Most Tippmann's need a tank with at least 800 psi output to function properly.

My bet would be, given the age of the marker, that it is time for a spring replacement.

Here's the straight and narrow of it. HPA tanks output at two pressure either 800psi or 300 psi depending on whether it is a LPO or HPO tank. Of course, the exception to the rule is adjustable regulator tanks, but we won't get into that for now.

Pro-Lites come from a time when HPA wasn't even on the radar. Due to that fact, the valves are built to run off of higher pressures than what most guns run on today. A Tippmann '98 runs fine at 600-800psi input pressures, but Pro-Lites are built to take almost 850psi. Because of this, they run fantastic off of CO2, but run like crap on HPA/N2. They are physically starved for pressure by the output regulator on the HPA tank.

That's not to say there aren't HPA tanks you CAN use to run a pro-lite, but they're usually bulky and much, much more expensive.

The best thing to do for winter play is to invest in a couple of anti-siphon CO2 tanks. These are matched to your marker's ASA (so you'll want to mark which one goes to which gun) and essentially keep the valve from sucking up liquid CO2. Since gaseous CO2 has a constant pressure of 850psi, you'll never be short of oomph to get the ball up to speed, and you won't have to worry about sucking up liquid CO2 and having the marker shoot "hot".

Now, the .68 Carbine and Pro-Carbine work better on HPA as they have different valves, but still not as well as a 98 would.

Hope that helps!
