Hi Bud:Since you did some delivery in your youth you know the disaster that can result from an oil spill. Delivery drivers are seasonal so chances of getting an inexperienced one are high. Our old regular disappeared years ago and now it is a new face all too often. No obvious solution to offer.
I wrestled with my supplier until I determined my concerns were a bad fuel guage. Replaced it and now don't get panicked as before.
LOL, just pretend you have a 225 gallon tank.
Maybe you are a good person to ask. My 275 gallon oil tank is only about 7 years old. I need to get behind it to repair a basement wall crack. Is it a big deal to disconnect and shift it a few inches away from wall and move back after repair? I can wait until it is almost empty or lift gently with a pallet jack. Just need to scootch the back end away - feeder line end can stay as is.
