Interesting thing happened on Saturday. I was doing musical chairs with all my trucks so I could get the Suburban into the garage to replaces it's radiator and heater core.
I started the ff PW and it was just a little more difficult than normal. I backed it out of the garage and part way down the driveway. Then I noticed a long wide fluid trail that followed me with a large puddle at the starting point. I shut it down and went to look. It was gas. I looked under the truck and the front differential was just covered with gas. I popped the hood and the fuel pump as soaking wet as was the engine block in that area. I let it sit and went to the interchange page on this site and got the NAPA fuel pump number. Called my local NAPA store at 11:30 and they said they would have it by 2:30. Picked it up and it looks to be a high quality unit (but no gasket for it, luck that I already have 2 of my own). The strange thing is I moved it a couple of more times Saturday and it did not leave a gas trail like it did earlier. Strange.
Now I know why it was not running well last Thursday when I tried to drive it to work. I could not accelerate. It just went flat on me no power. It obviously had a fuel delivery problem.
Obviously it appears to have a ruptured diaphram in the fuel pump as it appears to be pumping gas out of the breather hole in the pump. Now I have to do a oil change as I would suspect that gas went down into the oil pan (darn just did one of those). The new pump goes in later this week before it is started again.
