E-LSA or S-LSA?

ELSA - I assume this is the small rubber-ish hose that we remove to conduct carb balances?

With E-SLA, you have freedom to use whatever hose you'd like. I replaced coolant and vacuum hoses with High-Performance Silicone Heater Hose. As I recall the hose for the intake manifold crossover was an odd size. Photos show thick wall hose used for this application. I sourced from HPS. Below is spec for tubing used for crossover and for coolant overflow tank...

HPS 1/4" ID Blue High Temp Reinforced Silicone Heater Hose Tubing, 6mm

I used NAPA H179 0.4375 inch I.D. for the Rotax compensating tube.

The hose described in the MM revision is the small diam. hose that goes between the nipple on the crossover tube and the MP sensor.
