When using the Firestone Coil-Rite Air Helper Springs Part # F4136 on your 2015 Toyota Prius you should not have to add air on a regular basis. I sometimes see a slight pressure loss when it goes from hot outside to cold and you'll have to add a bit to get it back to pressure similar to the way a tire on a vehicle fluctuates up and down slightly with weather.

If you are adding air on a regular basis to the bags to maintain your desired pressure then you have a leak in the system and should address it. Use a soapy water solution in a spray bottle and check the entire system for leaks which will appear as a growing bubble cluster. If it is at the bag connection or at the air fitting connection remove the air line from it and re cut it using a very sharp tubing cutter like the Air Lift Air Hose Cutter part # AL10530 . If you discover a leak in the air line line itself then you can trim it out and reconnect the line using the Firestone Union Connector for 1/4" Tubing part # F3079-1 or replace the line completely using the Firestone 1/4" Air Line Tubing part # F49ZR .
