LoneWolf2U 136 Report post Posted June 20, 2020 Yes, But make sure the cap is vented or you still have the fuel canister vent set up installed. Quote Share this post Link to post Share on other sites

LoneWolf2U 136 Report post Posted June 20, 2020 look at the top of the fuel tank, In the left front corner will be connection points to the charcoal canister in the engine bays drivers side front with tube to air cleaner. If not there the cap must be vented or damage to tank may occur and engine run problems pop up. Quote Share this post Link to post Share on other sites

LoneWolf2U 136 Report post Posted June 20, 2020 simply drill a 1/16th hole in the center of the cap like the old one. Quote Share this post Link to post Share on other sites
jmlay 80 Report post Posted June 20, 2020 Look at the face of the fill tube. Typically there will be an indention on the face that serves as the vent. Quote Share this post Link to post Share on other sites
