    Generator runs perfect without system, after hooking up the tank the system runs for a little while then starts surging then dies. Checked the fittings but can’t find any problems

    Extended Run Tank fir Predator 3500

    Posted by Tim Zwieg on 15th Nov 2022

    The extended run tank is great, does exactly what it says it does. No filling generator in the middle of the night. The two plastic clips to pinch the airline off seem cheap and can break at anytime. They sent two wasn’t sure if that was in case one broke or not, but honesty needed them both to close off the air line. The documentation that came with generator could be better. They meticulously told you to make sure the tank is elevated above the generator, that is great. They forgot yo mention that the tank is not vented and use the cap needs to be loose else generator will vapor lock and kill. Other than that great item

    System works good. Had a couple of problems to start with and Dan helped tremendously. Sure is nice having the generator run for several hours before filling with fuel.
