Hello,

I previously posted about fuel pump pressure, and replaced the pump, which fixed the hard start problem.

It turns out the pump had been previously replaced in 2009 with a Ford pump.

I was paranoid about stripping the bolt holes, so I bought an inch pound torque wrench, and torqued them first to 20, then 55, then 89 inch pounds.

One of the bolt holes gave out before I got to 89. I backed it out, and tried again, and it continues to weaken.

Does anyone have any creative ideas on how to remedy this?

Thank you.
