fuel leaking from intercooler boot?
hey there, thanks in advance, i have a 02 f350 7.3. have started loosing fuel from where i think is the cold side boot of inter cooler (passenger side, just below battery) any ideas on what this could be? seems like under pressure or driving this area dumps a fair amount of fuel, not so at idle and it has taken me some time to find source as the fan has sprayed fuel every where, fairly new to power strokes but pretty comfortable with most wrench jobs.
thanks again

Check the valve on the back of the fuel bowl. It's got a yellow handle and is used to drain the fuel bowl. It leads to a metal tube on the passenger front side of the block. The orings go bad and cause leaks on occasion.

Your talking about the 3-4" aluminum fitting with the blue boot from the intercooler? There definitely shouldn't be fuel in those tubes but sometimes oil accumulates and i suppose that could leak out. The only other thing I could think of would be condensation from the a/c lines or a leaky radiator bottle. Your sure it's diesel leaking?

Its fairly involved and time consuming to do, pull both valve covers, pull the injectors, remove the old cups with the puller tool, clean sealing surfaces, install new cups, allow time to cure, pressure test coolant system, flush coolant system, and put it all back together. I'd be bummed.
On the plus side I think it's fairly cheap if you can borrow the specialty tools from someone.

Clay at riffraffdiesel.com has the cups, sealant, and rents the tool.

It's time-consuming. You'll pay waaay more for the labor than the parts. Parts/supplies to do all 8 (properly) are about $250, and that includes the tool rental. I'm not saying you should tackle this, as I wouldn't wish this little chore on anybody... but good luck finding anybody to do it without thoroughly hosing your wallet down.
BSTW is a great resource, he re-did his 7 times and knows all the things to avoid. I had great success with mine, but I made one mistake on one cup and I tried to get away with it. It came back to haunt me and the redo was painless, once I followed my correct procedures.
