Well I can use some of that 1-1/4 ID  transparent hose sold in Home Depot
to connect rad to pump and see what it looks like on the dyno.

Not if you plan to get it hot you can't.  That tygon type stuff gets

soft at 200 deg.  Mcmaster sells nice sight glasses for pretty cheap.

If it burst or swells up I can shut down the engine. I also think I

can buy

1-3/8 inch plexi turbing. I'll check the Mcmaster cat.

Would you be able to use a pool sight glass?  They use PVC coupings.  I

think the sight glass itself is usually acrylic.

I checked Mcmaster. Jeff is right Tygon is bad.
Chemflor clear on the other hand is good to 400 F but the biggest it comes
is one inch ID which might be OK on the dyno. Page 65 Cat 105

Did you look under sight glasses in Mcmaster?  I've used the brass/glass
ones with good success.

Jeff Spitzer

Not cheap in the size we need.
