This article describes replacing a stock fuel pump with an unapproved aftermarket replacement. If you attempt this procedure, you do so at your own risk. You will be dealing with electricity and flammable liquids. Explosion, burns and death are possible outcomes of attempting this procedure. You are fully responsible for all results. OK, now that we have that out of the way . . . Has your GL1500 died under conditions of hot ambient temperatures and high load and then mysteriously restarted and ran fine after it cooled down? You may be experiencing a weak fuel pump.

These instructions must be read and understood fully before beginning installation. Failure to follow these instructions may result in poor performance, vehicle damage or personal injury. If these instructions are not fully understood, installation should not be attempted. Please consult with BLP Technical Services or a qualified engine builder.
This pump is designed to mount directly inside the crank-shaft pulley on Chevrolet small block (305 & 350 C.I.) engines. The maximum recommended pump speed (engine speed) is 5200 RPM. The maximum recommended discharge pressure should not exceed 10 PSI. When the pump is installed so it operates at or near maximum speed, the inlet plumbing must be designed to minimize the vacuum at the pump inlet. A high speed scoop over the inlet thru-hull fitting is recommended to reduce inlet vacuum.
