Default 1/2" molded tight offset hose?

In a bit of a bind. Using square port ITB's on 5.3. Had to use manifold adaptors that shifted my intake up and aft. Now the hoses that connect all the throttle bodies don’t align. But there is little to no space to work with. I put a stretchy hose on and I don’t think its going to work well. Curious if anyone knew of a rubber offset hose that looked similar to this or had any other ideas.

Anyone stumbled across a hose that may work in this situation by chance?

As the Brits might say, that is a bit of a sticky wicket!
This might be a bit extreme, or not work at all, but what about cutting both nipples off at an angle, then rotating both to meet each other and rewelding/brazing? Then a short hose to connect....
Just a bit of random thinking here....

Vacuum only. Theres a sealed chamber on the Valley cover that ties the LH and RH ITB’s together. Each individual TB is tied together as well. All to give a decent map signal I assume. Also the center chamber has the IAC valve on it. I could possibly disable it all and run the map off one bank easily enough. But I’d lose the IAC control.

I would just clamp it and run it.

3d print something. you can brush it with thinned epoxy if you are worried it will leak enough to matter.

If it's just vacuum, this might be your fix. You should be good as long as the hose is flexible enough and won't split or crack from the stretching required to fit.

What do these hoses actually DO?

Could you use the rubber end & hard plastic hose to make them up?

Could you drill holes in the casting and put nipples in those, rather than hooking to the TBs?

They equalize the manifold vac signal from LH to RH banks of individual throttle bodies. Also provide vac to brake assist

Definitely keeps those. They make an ITB setup much easier to tune.
