1st off- thanks mrpeal, it was the feul pump connector.

I just dropped my gas tank and fixed a connection to the elec. feul pump, reconnected the filter & fired her up.
TAP! TAP! TAP! TAP! TAP!
What the heck is that It's LOUD and it speeds up upon exceleration. It's definately coming from the motor and nothing is hitting the fan.
Is that what a broken wrist pin sounds like?

And why is it that every time I fix something on one side of the truck, something takes a dump on the other side THE SAME DAY?!? as Charlie Brown would say: AAAARG!!!!!!

okay, it get's even better!
I just drove it around the block to see how well it would get me to a garage and the noise is now almost gone! I'm thinking now that the oil pressure is up it has 'lubed the problem'.
thought that info may help. This is makin' me nuts!
