A "Red servicing unit or a "Blue" cashier normally operated unit?

Pressure sensors are span maxing out (signal pegging) and going into alarm. Duration of monitoring of the over pressure event is to long before registering the alarm. Drivers when filling to fast out of compliance for reasons such as being in a hurry will drop at a rate for example where vapor volum...

I figured people would read the post on tank Over pressurization and vapor migration during a delivery. I fear that most still have no idea what I'm tanking about. What's happening in the tanks empty space during a bulk delivery is not actually something one can see with the human eye. I can only sa...

Without an adjustable motor column adjusted for the shorter motor the pump would stop pumping 5-inches further from the bottom. Make sure when the dispensers start running slow you still have enough fuel in the tank. If your working off the bottom up and running low typically you may end up toasting...

Why would one step down a motor size?

Tank Rats maybe.

One wonders how saturated vapors causing low PH and corrosive atmospheres are migrating from tanks into sumps during such events? All but an idiot would realize that ullage pressures exceeding 1 or 2 psi during a bulk fuel drop, will force vapor migration to atmosphere through loose or over pressure...

We observed 75 bulk deliveries between December 24th, 2018 and January 1st, 2019. A total of 75 deliveries being 25 in Metro Atlanta, Georgia, 25 in Metro Kansas City, Missouri and 25 in Metro St. Louis, Missouri. 24 out of 25 deliveries observed were being made in a condition considered Out of Comp...

In all cases. I say ALL. SUMPS On sites where corrosive issues in associated and or connected sumps, on equipment or a system component connected, a tank or all tanks associated within the farm will be leaking when over pressurized. Tank(s) where saturated hydrocarbon vapors and or lower than normal...
