I think it's great that you are doing something different, not following beaten path.


Thanks.... it's a curse I learned from my father..... question everything....... believe nothing..... and prove things/ideas to yourself.... then you'll know what works. <img src="/forums/images/graemlins/rolleyes.gif" alt="" />

the long, not supported piping at the end of the fuel rails could become a fuel rail fatigue problem in the future.


I agree, but could not find a better solution for the fuel line routing - or for the fuel rail. I wanted to build custom (stronger) fuel rails, but the offset fuel delivery bungs necessary to clear the lower intake don't leave much choice except to adapt the OE fuel rail. With a liberal dose of Permatex #2 used as thread sealant, it does "feel" stronger than it looks.

Sometimes fuel rail material is not very well weldable and welding can produce cracks in the material. I don't know is this your situation, but I've found soldering very helpful in these cases.


I understand your suggestion - and agree that the material isn't the best for welding - but I have (at least) 3 pin holes that appear to be near the center of the welded hole.... not a bonding issue (I *think*) - more like a gas path during cooling.

Calling all welding gurus:

My welding experience is limited to a few passes of stick welding in college engineering classes about 40 years ago. I've ground the center of the weld in the area of the leaks to a bowl shape.... depth of ~ .050". Is it deep enough for TIG welding to fill - or should I grind until the hole is reopened?
