Where were you measuring and what pressure were you getting?jumpinjimmy wrote:......I've already done the fuel pressure test which is what made me decide to change the pump (outside the fact that it was an original part and very noisy). There was too much pressure which indicated the relief valve was not working properly.

For clarity, are you referring to the test on the last page or the second last?jumpinjimmy wrote:I used the test outlined in this PDF for testing the pump and according to this article it was the relief valve in the pump that was bad.

It would've been useful to know what pressure you got with this test. It may have explained a kinked fuel line in the tank.jumpinjimmy wrote:I used the test outlined in this PDF for testing the pump and according to this article it was the relief valve in the pump that was bad.

Its not a hard road to venture down. Very easy to do.jumpinjimmy wrote:Thanks for the responses. Never backfires and it always!! starts right up...even now with this problem. Check valve clearances?? I'm afraid you'll have to explain the reasoning before I venture down that road.
