I am new to this group and glad to aboard. I am looking for any information on a 1987 Chaparral 187 XL with the 3.0 engine inboard. I am trying to find out what material is the internal fuel tank made of? Plastic or steel, aluminum? Can it be removed easily or is it a pain? The fuel cap was missing and was exposed to the elements for many years. I have a bariscope but havent looked inside yet. Any information from the pros on here would be great! Thanks in advance! Razer
