I have read through a lot of posts about this, and have only ever saw the fuel pin oring of being at fault.

The fuel leak on the IP was equivalent to a slow drip. So, I replaced the fuel pin oring with one in the Bosch kit. I started the truck and fuel eventually started spraying out of the vent. I replaced it again and it is doing the same thing.

Any ideas, because even if the oring was nicked it seems hard to believe that much fuel could get past a nick? I am confused!

 

You sure the fuel isn't leaking from the fuel drain banjo bolt? Do you have a aggressively ground fuel cone/pin? That will allow the pin to travel too far and cause a leak.

 

I have a Denny T fuel pin?

When it was dripping I had a hose attached to the aneroid vent to make sure. Fuel was only coming from the vent. I dont have the rubber cap on there so it had enough pressure and volume to hit the master cylinder?

 

That's a heck of a leak!

Past the o-ring is the only way fuel can get in there.

 

Thanks! I guess I will have to check tomorrow to see if the pin is traveling too far? If I have to tear into this again, I'll be looking for a hole plug!
