Installation Notes

Verify tank capacity and vehicle configuration before ordering, since this strap is specific to 25-gallon tank applications and certain behind-rear-axle layouts. Confirm the vehicle year, make, and model against the fitment list, including Chevrolet Blazer, GMC Jimmy, and related Suburban and C/K truck applications. This part cross-references 578012 and KST12 for the same application.
