Note if this product is to be used with aftermarket (tall) EV1 performance injectors:
• LS2, LS3, and L99 applications will require taller brackets and
Adapter O-rings to be used with EV1 injectors. Holley part number 534-212 will have these required parts, but is not yet available (expected availability in mid June 2013).
• LS1 and LS6 application will work with EV1
Injectors without any additional parts.
Holley part number 534-211 (expected availability in late April) allows easy connection to factory fuel lines. These
Fittings are available from other suppliers if needed before release.
