If it was connected right before they started the engines then probably it was the air hoses for an air start unit..if an airplane doesn't have a working APU ( Auxiliary Power unit) then it needs compressed air from a source on the ground to start the jet engines.
Other things connected to the lower part of a plane on the ground are an electrical cable for ground power, a large hose for Air Conditioning, and a medium sized hose used to drain the lavatory waste. Oh an a small hose used to fill the water tanks.
Fuel is usually loaded through hoses that connect to the wings of most aircraft, not the underside.

Fuel on all Boeings /Airbus are in the underside of the wing. Smaller regional jets fuel at the junction between the wing and cabin.
All fuel hoses are black, waste water hoses are usually blue and typically connect to the tail, potable water hose looks like a garden hose, big yellow tube is air conditioning. smaller black cable snapped into the nose is ground electrical power, And immediately before pushback the tug driver connects an audio cable and microphone jack into the nose to talk to the pilots while they are pushing or towing the plane.
If it is an air start, it would be a hose about 4-6 inches in diameter usually connect around the tail or engines.
You decided what you saw. I don't quite understand your question.
