Fixed my leaking HH ...woohoo!

[ccf460]

My truck has always had a fuel leak coming from the HH. After several degreasing search missions...I finally saw it leaking around the center bolt on the top of the HH. I took the bolt out , saw there was no copper washer....? Wonder how many trucks are leaking in this area. I found an o ring that fit tight around the bolt shaft. As a side note, the hole is chamfered to make room for the copper washer, so I figured the o ring would fit in there also. After installing the bolt with o ring, the fuel leak is gone. I hope this helps someone else.

Mine is leaking from one of the line fittings. Can't get to it with the other lines attached without a crows foot wrench, so I have to remove a couple of lines. Only leaks when it gets hot though.

You may need a new injector line. I have 3 leaking. Just received 6 new ones from White Owl.

The center bolt on my HH started leaking after I turned up the fuel. I just loosened it and retightened it. No more leak.

Wonderful... Just what I needed to hear. Lol thanks though, I'll keep it in mind when I get to mess with it.

no copper gasket here and certainly no o ring! way too much pressure for that. it is just a interference fit.
