*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.
