Other Fuel Things
usually specs mean algae, but what other things can you get in the fuel bowl that are black floaties?
I drained it yesterday and had black specs like Algae, but the filter was clean as I when I put it in, which is amazing me.
So, what else could be in there?
I know I"m pouring fresh fuel in next time. I dont like cranking that long.

x2 .. best guess. When I replaced my lift pump last year had the filter canister completely empty, added new filter and did not add any fuel. Well to my surprise it fired up really quick, as normal, and that was after three days sitting empty. I keep hearing if you drain the filter you should always fill the reservoir or you have to crank forever. However that has not been necessary for me. Go figure ...

I might have caused this problem, honestly.
I uped my fuel pressure with the BB mod. So, the injectors are having a harder time.
I was down a qt of oil the other day, and now I havn't lost any again.
I figured I had some blow by.
I got lots of white smoke on start up, sometimes there is a bit of blue in it. So, I need to re ring my injectors. But that really makes me want to throw in Stage 1's. while I'm in there. Better go win the lottery first.

The BB mod shouldn't cause it. One side of your o-ring is seeing 70 psi of fuel and the other is seeing 500-3000 psi of oil. That's why the orings end up in the fuel system. Oil getting past the seals erodes the o-rings and blows the chuncks into the fuel rail. If it gets bad enough, you will find your return lines full of oil. I did.

You have a two stage mechanical pump. The fuel is drawn from the tank by the 1st stage ( the diaphragm) and fed to the fuel bowl where it's filtered. From there it goes back to the 2nd stage (the piston) where the pressure is bumped up and it's fed to the injectors via the fuel rails in the head. Any unused fuel goes to the pressure regulator on the side of the fuel bowl and then returned to the tank. Once the cycle starts again it's pumped back to the bowl where any pieces of the o-rings are trapped by the filter and you see the black specs in the fuel.

The BB is used a a shim to increase pressure on the spring in the fuel pressure regulator. Old tired and weak pumps have trouble maintaining pressure and the BB brings it back up to assure that the injectors get their full shot of fuel in the alloted time.
