Do you still have the red travel pump in your pump?

 Did you know that when in use the oil will expand when it gets hot and can cause oil seals to pop out if you are not using the vented dipstick. That is why we ship one with every pump sold. Please make sure to swap the travel plug out for the vented dipstick.
