[Shop-talk] 99 Suburban, Fuel Pump lock ring (snap ring style) failure

[John Innis]

I recently (like 4 weeks ago) replace the rusted out fuel tank on my '99
Suburban. I did the whole 9 yards, new tank, new pump, new straps, etc. But
today, when I filled the tank, gas started gushing out from under the
vehicle. Looking at the opt of the tank it appears that the snap-ring style
fuel pump retainer has failed and the pump is pressed up out of the tank.
Anyone know why this happened? Did I just get a crappy snap ring? Is there
some other step I was supposed to take after installing the lock ring? I
have to say, I don't think this is an improvement over the old rotating
style lock rings.
