Installation Notes:
*Pump gas compatible for intermittent or under 90 degree ambient temperature use Pump gas use recommendations: • This pump is compatible with pump gas, but is not recommended for street driven vehicles where the ambient temperature is regularly above 90 degrees • For street driven vehicles in high temps with pump gas, Holley recommends part numbers 12-600 or 12-800 for optimum hot fuel handling• Proper fuel system engineering is critical for maximum performance. Please see Holley Fuel System Chart for information about proper installation of your fuel system. Will work with E-85 and Diesel!These pumps do not have an internal bypass. A bypass style regulator and return line are required. NOT FOR USE WITH METHANOL! This pump is not designed to use a standard conical seat style union in the inlet or outlet of the pump. Example: Part # AT981508ERL. Use of this style fitting will block flow and WILL lead to poor performance and pump failure. The ONLY correct fitting to use is a contoured port fitting with an O-ring seal such as :Part # AT985008ERL.
