Fuel tank question
 

Anyone know anything about the factory fuel tanks in a 93 era Shabah? I changed out the anti-siphon valve and was going to put in a new pick up tube but when I pulled off the 90 degree elbow that's all it was, an elbow. Looks like it is a welded in pick up tube. My biggest concern is does it have a screen of some sort on the end?? Having some fueling issues I can't figure out. Thanks in advance.
