Tank is made of plastic….

Thank you. 😊 The digital gauge is a dash display and logger, Plex SDM-500. It shows all essential data from the engine, even torque when driving. It also gives warnings, and can log data over time. This unit will not work with the original ECU, this car has Life Racing F88RL ECU. 😊

Exactly, once started engine must at least reach operating temperature and car should be driven, better leave it alone otherwise or you're destroying it.

Starting and idling stops surface rust on inside of engine, prevents fluids and coolant congealing and prevents joints etc from seizing, also good for fuel pump, oil pump, hydraulic pumps etc and lubes gaskets. Whats not to love?

I drive it almost daily in the summer. 😉 But where I live, there are salty roads everywhere in the winter, and I wouldn't put the car through that sh**. After all, we are talking about old Ford here.. 😄

When you buy one you can treat it how you like.
