Hi all,

XJ 1985 2.8L manual with big problems on Rochester carburetor , therefore I thought to replace
which is the best solution ? weber ?
weber carburetor also has hoses with the vacuum system ?
thank you

Giacomo

 

Weber 100%

 

Thank you freegdr
so WK490- 38 DGES Weber ?
but also the weber has links to the vacuum tubes ?

Giacomo

Rochester R2 E2SE (W) 2.8 Ltr. 84-86 38 DGES

What changes compared to my kit ?

Giacomo

 

Nope same as what you got 38 DGS with kit WK 490

 

And yes there will be ports to hook up vacuum lines.

 

but it goes well for 2SE ?
if you do not connect the vacuum lines what happens ?

Giacomo

 

Found this...Part No. WK490
Note: Jeep and GM fuel pumps typically supply a high or inconsistent fuel pressure to the carburetor. We strongly recommend the installation of a Holley 12-804 fuel pressure regulator set to 2.5 psi for correct operation and optimal performance

 

Certain things will not operate as designed causing poor running issues bad fuel economy.

Theres plenty info here.....
