Today me and my dad drove my car home and it drove home fine without any tank sediment problems like b4 but, I put a cheap clearview filter on it, to see what contaminates exzactly were going to clog up the filter ( nothing clogged though ) and when we got it home we inspected the filter, it was only half full of gas and the car was running when checked, is this normal? or is it vapor lock? The guy b4 me cut the hard line and put in the 3/8" rubber line for about a foot and spliced it togther ( I'll put a good filter and redo the hard line later ), would this cause it? Also, the wacky thing on the side of the motor ( near the fuel pump ), it comes off the block and is about 6" long and has a hose that comes off of the side or bottem of it ( can't remember exzactly ) but, when the engine gets to temp, it shoots small amounts of smoke or somthing like that out of the hose, what is it and, is it suppose to do that? For ne one that dosen't know what motor it is, it's a 235 str8 6.
