The uat tank it’s not very important what brand or how it looks like the biggest problem with all the fuel supplies are that the builders use thin vent lines the should use at least the biggest tygon line or 6mm if the uat collapse doing fuel drainage or full throttle turbine operations it’s for sure ventilation problems not the uat even if the uat filter its completely clogged up it will never cost the uat collapse but usually never happens and it’s very easy to fix just regular service and cleaning ,so how the uat looks like or what material is been used to make it doesn’t really matter make sure that your vent work properly and all is going to work great for years.
