Hi all,

I'm installing a new fuel filter on my US '97 XK8. Can I relieve fuel pressure by removing the fuel pump fuse & relay and run until it stops?

Also any one know the size of the O rings? Part # is XR829166. Hate to pay $5.00 each at the dealer if there is a comparable substitute.

Thanks,
Marty

 

There is a schrader valve on the fuel injection rail. Depress it with a small tool and have a rag ready to absorb the fuel.

 

Anyone know what size o ring I need?

 

It is probably not a good idea to use a hardware store o-ring...it may not hold up to the gasoline exposure.

 

Thought I might be able to get them at an auto parts store.

 

I picked up a kit from Harbor Freight, contains various sizes of Viton o-rings. I've replaced all of the-orings in the air lines, dip stick, PCV, MAP sensor and valve cover breather connectors/fittings. They've held up well. Whether or not the kit has the correct size for your shrader valve, I'm not sure.

• High temperature resistance.
• Excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals. Low swelling in ASTM oil No. 1, and IRM 902 and IRM 903.
• Excellent resistance to aging and ozone.
• Low gas permeability, low compression set.
