OK, I have an 87 blazer with the fuel tank skid plate and the straps are broken and the tank is setting the skid plate. It also has a return fuel line leak. SO, I'm going to drop the tank and try fixing the return line and I want to do the new straps when I have the tank down, but LMC lists a 25 and a 31 gallon tank for that year. Any idea on lengths by measuring or do the skid plates only come on the 25 gal tanks or can you get them on both. My other 87 blazer has a 31gal tank and no skid plate. Any one know the measurements of the straps or the tank for the 31/25 sizes?
