1st fuel pump change
Got the opportunity to change the fuel pump on my 1993 Blazer this weekend. Not bad except that I had to do it twice because the part store gave me a pump for a TBI, not for a CPI, like i asked for. They look a like but as I am sure you guys already know one puts out 13# and one puts out 60#, big difference.
Changing it out the second time was a snap.
One thing still gets me, how can you have electric connections submerged in gas? My mind keeps telling me that sould equal trouble but i know that is the way it is supposed to be. Still makes me think of a mob hit from the movies every time i turn the key.

I've never switched out a fuel pump, but even though it looks wrong to have the wires submerged in gasoline, that's they way it was designed. It's stupid, but it works.

Well I dont think that they spark for one, and secondly in the tankthere is a lackof O2 which is required for combustion.

What I had the most problem (mental that is) with was the burnt wires at the harnes that connects to the pump itself.
I think that I have checked everything that could cause that, fuel filter, strainer, checked voltage, but pulling melted wires from the gas tank will get you to thinking.

That really seems strange to me too.

Are those wires soldered?

Those melted wires are some kind of desighn flaw, thats why every fuel pump i have seen for these models says replace the harness at the tank. hopefully its provided with the pump. it wasnt with mine so it took a little work running one down.
