Must have for tight spaces

Comments about AN921 O-Ring Boss Adapter - 90' Elbow:

I needed (wanted) after market fuel rails in my 1993 RX-7. It is an autox car and needs more power (don't we always), and more fuel required more modern fuel injectors.

The challenge is fitting new fuel rails and associated plumbing in what is a rather compact space. While there are other 90 degree boss adapters, they generally take up more space than these do.

Perhaps the most important benefit is that locking ring - these are the only boss adapters I could find that both fit and could be clocked in whatever direction was needed to fit the fuel line plumbing.

Service and delivery comments:

I have used other vendors. Pegasus is the *only* vendor that always has the parts in stock, and gets them shipped immediately.
