If you'd said that in your first post, I'd have suggested what's worked for me for years...

... how I disconnect those two fuel lines (without going under the car):

1) The larger rubber pump OUTPUT line.
Cut or saw off the rusty hose clamp, use a screwdriver to "assist" the hose off the sender fitting. Refit hose to new fitting. Refasten with a new hose clamp.

2) The rubber covered hard plastic RETURN line.
I avoid going underneath to tangle with the rusty fitting that connects plastic line to (often fragile) metal line.

Use a razor knife to cut off about 2" of the protective rubber covering on the black plastic line. Then cut the plastic line free at end of metal sender barb fitting (I use a small, fine-blade hacksaw.)

Reconnect the cut plastic end to new sender barb with short piece of 5/16" I.D. fuel hose and 2 good hose clamps. NOTE: Return line is low pressure. IMO, FI rated hose is not needed here, standard Fuel Hose is good enough.
