Paul,
  I've been looking for anti-collapse hose for my radiator return, but have
  been unable.
  my solution is to insert aluminum flex hose inside my radiator return hose.
  it's 1/8 inch smaller than the inside diameter of my radiator hose.
  I'll make sure the ends do not chaff the inside of the radiator hose.

  Do you see any potential pitfalls here?

  That looks like a better solution  than the corrugated stuff Chuck Dunlap
  used. Smoother inside.

 Hey - that looks exactly like what I was wishing for on our install as well.

 We (like Chuck I suspect) are using the corrugated rubber hose lines in
 order to get a 90-degree curve.  I have always thought the corrugated hose
 is not doing good things for coolant flow.  Our attempts to use the silicon
 hose have always failed because it collapses in the bend.  I'll be very
 interested to hear how well this works.

 How do you plan on eliminating end chafing?

As an aside, it's possible to buy silicone rubber hose elbows (90 deg
plus other amounts of curve)..

Matt-

Brian has added a false bottom to the RV4 much like a P47 and mounted
the rads back almost as far as the P51. It will look much like a P51
from the side when he gets it done. He has gotten so good with the
english wheel making aluminum cowls the Me262 project has hired him to
make parts.
