Frequently Asked Questions

Q: Can I use a Non-Macnaught 18V Battery on the BOP?
A: No, BOP requires a Macnaught Battery

Q: Can I store the Powerhead outside?
A: No, the BOP Powerhead is not rated for rain conditions. Store the Powerhead in a dry location. Caution: Do not drop the Powerhead- damage can occur at any distance drop.

Q: Can I pump diesel with BOP?

A: No, only the rated fluids. Yellow Ring designates Hydraulic or Engine Oils, Green Ring designates Coolant, Red Ring designates ATF

Fuels of any type are very dangerous to pump and will damage the BOP seals. Only Oils, Coolant or ATF. No other fluids are warranted.

Q: Can BOP be used for Marine Outboard fills?

A: Yes, we have many Marine Mechanics using BOP for this application. You will need to modify the Nozzle Tip to accommodate the type of Outboard connection you will use

Q: Is BOP 3A or Sanitary compliant?

A: No, BOP can only be used with rated fluids.

Q: Does BOP work with 2.5 Gallon Jugs?

A: Yes, BOP20 does fit

Q: Will BOP fit into my Oil Safe or other containers?

Yes, BOP20 fits perfectly with 5-liter and 10 Liter Oils Safe Containers with their Utility Lid.

The BOP20 also fits Des Case 7-Liter and 10-Liter and Trico 3-gallon and 4-gallon containers with Pump Lids.

Q: Can I run the BOP dry?

A: No, do not allow the BOP to run dry. Impeller damage will occur.

Q: Is the BOP serviceable?

A: Yes, we have Impeller Kits in stock.

Q: Do you offer a meter with the BOP?

A: Yes – easy to install and operate

Q: Can I use an Oil Control Gun with the BOP?

A: No, non-drip nozzles will not operate correctly with the BOP.

Use only the BOP Inline Digital Meter IM012EB-01

Q: My 5 Gallon Pail is an odd size, will the BOP20 work?

A: Yes, the adapter fits most pail bungs and the BOP comes with an adjustable sleeve to evacuate fluids on taller pails.

Q: My BOP is running slower at cold temperatures – why?

A: Oils thicken with lower temperatures, and cooler weather will slow the BOP flow rate. We recommend keeping oil containers as warm as possible indoors or with heating blanket wrap systems. BOP works best at 60F plus.

Q: My BOP stopped Pumping. The battery is charged, Powerhead light is on – what do I do?

A: Inspect the Impeller for Damage or Plugging
