I found my pressure hose was leaking so I went to auto zone & got a new one and had it installed and now it doesn' work at all. He did check the pressure relief valve to make sure he put it back in right. The pump was working fine before. Never had any problems with it except for the leak but it is the original pump, 80 model truck with over 100,000 miles. Any advice out there? The mechanic did say the new line could be stopped up where it was crimped together. I went and bought a remanuf pump just in case.
