I broke the fuel rail on the 5.3 Yukon engine. I do have an extra rail but it is a little different.

Original rail: 2003 Yukon, Rail # 17202093, regulator??# 25325078 for ethanol fuel.

Replacement Rail# 17201017, Regulator?? #4252 15332

I tried to install the original regulator in the other rail (17201017) but it will not fit in the hole.

Would it be wise to look for another fuel rail or just use what I have.
