Holley electric pump rebuild kits? - Third Generation F-Body Message Boards

So my Holley "Black" electric fuel pump decided to die on me this weekend.One week after I put the car back on the road and start breaking in the new Richmonds in the 12 bolt!!!Well...it didn't actually die.Here goes...

What is happening is the fuel pressure will not go above 3psi.It fluctuates pretty steadily between 0 and 3 psi.Once in a great while if I idle around the neighborhood it will go up to maybe 5psi.I thought maybe gauge (in car Autometer with isolator) or regulator (Mallory #4309)..swapped both with known good parts..no change!

Then I realized.."I haven't heard the pump in awhile".This pump at running idle used to be pretty loud/couldn't miss it..and now with the car off and key on..it sounds like a fish tank pump.Real light "wiirrrrr".So I then tested the positive wire right before the pump and the fuel pump ground wire for full voltage and she is getting 14.5v at idle.The pump is about 5 years old..but only driven in the summer months and sits all winter.I run a return line on the fuel system and always keep clean filters before and after the pump.I'm not shocked if it is going bad as that is all I have ever heard about Holley pumps.My question is..is there anything anyone else can think to check?And are these things rebuildable with readily available parts from Holley?

No one has run into anything like this with a Holley pump before?

I have a Holley Blue on the way so I can get the car back to solid running..just wanted to see if I could rebuild this Black pump for a spare or just toss it.

I was looking in Summit and they had rebuild kits for red and blue but none for black. It could just mean that they don't carry it. I'd call Holley's tech line and ask!
