So searching lead to zero leads... but perhaps this stuff exists OR someone can suggest a workaround.

The issue is (not to get into it, the cts-v Gen I - garbage fuel design) uses 1/2 hard plastic tube (not 3/8 like every other system) to go from one side of the tank to the other for the jet pump.

Im complete in making a twin bucket system except for this cross pipe which now has to criss cross.
These hard plastic will not bend to fit.

Are there any 1/2" push on to 3/8" hose fittings?
Are there any 1/2" submersable 30R10 hose?
Fluoroelastomer - Is this stuff submersible?
