fuel rail damper

Hi,

I had to replace my fuel rail on my 2000 Jeep Cherokee Classic as it was cracked and leaking...

The fuel rail has a fuel damper in the middle of the rail, but i replaced it with one that doesn't have a fuel damper...

The stealership wanted 250$ but found one one ebay for 50$, it says it fits a 2000 jeep cherokee...

Does it matter if the fuel rail has a fuel damper or not?

Thank you
Mickey

I put a 2000 fuel rail on my 95 the did not have the dampener and noticed no change at all.

He's going the other way around...

Probably won't notice a difference. The damper is supposed to keep pressure within 1 PSI of 49, whereas engines without the damper expect +/- 5 PSI. CCKen's measured his 1999 that has a damper on the rail (Chrysler likes to do random things) and observed +/- 5 PSI anyway...
