Whizbang will become famous soon enough
Default Fuel pump is cavitating.

profanity, obscene language, vulgar words and well...fuck.

well i went to get the start up process going tonight and low and behold, the fuel system is going to be an issue. Originally, i had this problem with fuel flow to the engine. I had dropped the gas tank and saw that the pick up tube was mostly blocked by the orange crap the they inside gas tanks when they refurbish them. Though i had cleared it out.

Turn the pump on and i get the obviously sucking air noises from the pump, the fuel pressure will read around 45 (with some variation and its not very smooth). Then if i shut it off the gauge will extremely quickly plummet to 0 psi. Seems like its pushing a lot of air. Now i dont think i have anything wrong other than something still kicking my ass with the gas tank's pick up tube.

Now, my options are pretty much try and drop the tank and see if i can clear the pick up, or perhaps tap for a new connection. Money is tight and i have only 12 days til i leave for the Air Force basic.

stupid car.
