Thanks for all the feed back. I am going to try and rebuild my pump before purchasing a new one. I have ordered the o-rings from Napa. Found some fuel injected hose clamps and hoses. After disassembly I could see where possible leakage might have occurred around them. I also see some slight pitting in the o-ring grove. I would like to put some sealant on before reassembly. So far I have only found gas resistant products. Any suggestions for this product? Again thanks for the input.
