Found a purple Hayame FR-1 Fuel Rail in a box I had forgotten about. Appears from surfing around the purple ones were only made for two types of machines:
1994 - 2001 Acura Integra GS Coupe
1994 - 2001 Acura Integra GS Hatchback
1994 - 2001 Acura Integra GS Sedan
1994 - 2001 Acura Integra GS-R Coupe
1994 - 2001 Acura Integra GS-R Sedan
1994 - 2001 Acura Integra LS Coupe
1994 - 2001 Acura Integra LS Hatchback
1994 - 2001 Acura Integra LS Sedan
1994 - 2001 Acura Integra RS Coupe
1994 - 2001 Acura Integra RS Hatchback
1994 - 2001 Acura Integra RS Sedan
1994 - 2001 Acura Integra Type R Coupe

&

Honda Civic Si Coupe 1999-2000

No part numbers are engraved on it, anyway to identify fuel injection spacing, or bolt pattern to say what it fits?
Thanks for any help!

BTW, the pics make it look blue, but it IS purple...
