Electric fuel pump for a diesel
The diaphrams do go. My Yanmar was laid up with fuel in it for six years by
the PO and the diaphram in the electric fuel pump had disolved to about the consistency of tar. It was just a sticky lump inside the pump. The fuel had turned to jelly and I suspect it was the critters living in it rather than the fuel itself that ate up the rubber. Frogwatch wrote: In a thread a couple weeks ago, I talked about failure of my fuel pump on my 28' sailboat. It is a Yanmar 2gm that has a mechanical pump that I backed up with an electric pump to make bleeding the system easier. I am replacing the mechanical pump but I also need to replace the electric one. The electric one was from JC Whitney and I do not recall the brand. However, i do remember that it was not specifically listed as being for diesel. It is a simple diaphragm pump driven by a selenoid. I am wondering if the diesel could have eaten away the diaphragm. Can anyone suggest a good electric fuel pump fpr this application? JC whitney no longer has it available and I do not trust it anyway. However, the original owner had it installed when he bought the boat so I assume it was supposed to be good. When it finally failed 4 years ago after nearly 16 years, I simply bought an identical one. Any ideas? -- -- Roger Long |
