Fuel pump leak

The hole appears to be OEM because I did NOT drill it. During engine operation there comes a great spray of fuel. Bench testing confirms this malfunction. Manual does not show or talk about this hole. Why is it suddenly spraying" liquid gold" from a normal running engine"?
Is it a relief port that operates only when something else is blocked?
I have refrained from filling it with a pin or screw. Or JB Weld.
Any thoughts about function, or blocking of hole or it origin will be appreciated.

Maybe a bypass port that indicates a defective diaphragm? Might be discharging fuel instead of dumping it in the crankcase.

You photo link doesn't work for me.

 

I am going to assume this hole is on the dry side of the diaphragm and that it is a vent.  If so that means the diaphragm is leaking

The pictures "Another view..." seem to work if I left click then choose Firefox.
I agree it may be a relief port that is venting due to a leaking diaphragm .  I will disassemble and inspect and replace as needed. I will check this site for a replacement

That is because they are on your computer, you cam see them, we cannot.  The file address goes to the C:\ drive
