Will a vevor fill a tank

It is a small reciprocating piston pump with aircooling.

It will start to run hot after 10 min and max runtime is 15min followed by a 30min downtime.

It will fill at @ 6½ liters/minute.

A 74cu ft tank at what pressure???

At 3000psi max. the tank volume is 10liters or 610cui

At 4500psi max. the tankt volume is 6.65liters or 406cui

It will do 3000psi if taken care of properly but it will struggle past 3500psi and it will die if taken above 4000psi on a big tank fill!

Yes, he clearly did.

According to your maths, a 6.5-litre tank will take 1 minute to fill to 4500 PSI. All your figures are nonsense. The Vevor branded small pump is similar in size and power to the YH which is advertised as having a 50 litre per minute output. A 74 cubic foot tank only holds 74 cubic feet if the pressure is 4500 PSI. The same tank will only hold 6.8 litres of water or air at atmospheric pressure of 1 BAR. I understand that your English is poor but from most of your advice that I have seen in the past, you have little understanding of simple arithmetic as well.
