Boost Pump Selection

Gee! I would have thought the Vans RV-12 advice, would have caught the attention of Rotax Owner & Roger Lee

Attention  Rotax Owner & Roger Lee

I could do with your input

I've  posted about this on another post. You can use a higher rated pump to get a better draft height and a 1 - 2 psi increase vs the older spec'd pumps. This falls well within the Rotax specs for fuel pressure. The draft height may be the important factor for some owners. Faucet pumps make different modles. I've  8nstaaled better rated Faucet pumps on engines that had fuel pressure issues and the problem went away.

Thanks for that Roger.

One more question

Van RV-12 recommend - Facet Cube, PN 40135  - not fitted with a non return valve

What are your thoughts on using a pump with or without a non return valve?
