Relocating oil tank fill pipe

[chrisg]

We recently built a deck and need to relocate the fill pipe and vent for an oil tank that is in the basement. Oil tank will stay where it is but is there any issues with adding four 45 degree elbows (included 45 elbow into the tank as the pipe needs to work around a little bump out in the basement? Of course I would pitch the pipe slightly down to the tank but could use some guidance there as well.

I attached a mock-up of what I'm thinking. The distance of the pipe from entry point into the house to the tank needs to stretch about 15 feet.

Any help is greatly appreciated.

Shouldn't be an issue, just as long as they can hear the whistle coming through the vent.
