Coming from a diesel background it is a good idea to replace fuel filter every 2nd service as they are cheap insurance and easy enough to do on the Sportage

1997 Sportage - Extended forks, Dobinsons 2 inch front lift coils, rear Dobinsons TJ lift coils, GME UHF, $8 bullbar (I love eBay!)
2001 HZJ78 Troopcarrier - 2 inch lift, extended shocks, Ex Mine vehicle. Still has yellow reflective stripe! - GONE
