No they are different. The in tank hose will not go crappy after use. The inside and out side are the same material.
Down fall it's spendy, and only in 1ft lengths.
The normal efi hose can turn gooy and can swell. Down fall not really designed for intake use. But it's cheap.
Now if it rupture inside the tank no harm no fal unless u lean out and burn an engine up. Causing a back fire that catches the truck on fire burning it to ground. On the dyno catching the building on fire burning it to ground. Just a possibility.
