When I bought my '98 Suburban last October, the ABS was disconnected (wires were green inside). found a replacement assembly (module plus ABS block) on eBay for $75 and a harness in another auction for $25. Don't need it functioning to pass inspection in NY but wanted it working just the same.
When I needed the rear line for my '99 Suburban, I went with Gas Tank Renu. Nylon lines rated to 900 PSI, came pre-made to the correct length and fittings installed.
Fit Perfectly. and were only $99 for the rear set. Front also available.
