Fuel accumulator by-pass
How long will I get away with by-passing my fuel accumulator?
Mine started leaking. I tried to just plug the hole in the bottom with some epoxy, but it still leaks. I needed to test the engine, (I had just finnished a valve reset and wanted to test for oil leaks on the gaskets), so I just by-passed the damn thing. Car seems not to notice it's absence. Is this a common practice? Will I suffer some failure down the road? |

Thats what I figured. Since this is my "winter beater", Hot starts won't be a problem. I put the screw back in the bottom of the accumulator with epoxy, but it didn't hold. Should I have used something else? I can't believe there is that much pressure inside. Is there a cheaper fix than a $120 replacement?

sure, they should be dirt cheap on the used parts forum. a WTB post should turn one up. they do eventually start with sufficient cranking. it holds pressure against the fuel pump check valve to retain residual pressure for a while, for easy hot starting.

I have bought several used ones, several have turned out bad, one good. The diaphragm ages and leaks over time I guess. FWIW if its leaking pluggin it wont help with hot start. Same as a bypass.

Thanks for the info. My 76 911 gets neglected until winter. The damn thing runs so hot that I only feel comfortable using in in the winter. It's the only "70's" car I have thats galvinized, so I can justify giving it some winter use.
