system (pump, filters, regulators and lines). Please read all the WARNINGS and NOTES, as they contain valuable information that can
save you time and money. It is our intent to provide the best possible products for our customer; products that perform properly and
satisfy your expectations. Should you need information or parts assistance, please contact our technical service department at 1-270-
781-9741, Monday through Friday, 8 a.m. to 5 p.m. Central Time. By using this number, you may obtain any information and/or parts
assistance that you may require. Please have the part number of the product you purchased when you call.
2.0 WARNINGS, NOTES, AND NOTICES
NOTE: This system does not contain fuel system components that are required including the fuel pump, fuel filters, fuel
pressure regulator, and lines. These kits can be purchased separately (526-1, 526-2, 526-3, & 526-4).
NOTE: This system is designed for naturally aspirated V8 engines between 250 – 600 HP.
WARNING! The TERMINATOR™ EFI systems consist of a number of sophisticated components. Failure of any one component
does not constitute, nor does it justify, warranty of the complete system. Individual service items are available for
replacement of components. If assistance is required or if you need further warranty clarification, you can call
Holley Technical Service at the number shown above.
WARNING! To preserve warranty, these instructions must be read and followed thoroughly and completely before and during
installation. It is important that you become familiar with the parts and the installation of the TERMINATOR™ EFI
system before you begin. Failure to read and understand these instructions could result in damage to
TERMINATOR™ EFI components that are not covered by the warranty and could result in serious personal injury
and property damage.
WARNING! The oxygen sensor in this kit is recommended for use with ONLY unleaded fuel. Use of leaded fuels will degrade
the oxygen sensor and will result in incorrect exhaust gas oxygen readings and improper fuel delivery. Failure to
follow these directions does not constitute the right to a warranty claim.
