The weather in May is often fairly warm, hence the raised hood. These Zil chassis and their engines were never designed for static pump operations and had a tendency to overheat. Looking under the hood, you could be forgiven for concluding that they were not really ever designed at all, but just randomly assembled!
Russian pump operators, as observed in several videos, seem to avoid standing near the pump for some reason. In other countries it is more usual to be right next to the pump controls when it is being operated...
