Thread: A few quick questions.

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.

Filter half empty/ half full is normal. Sounds to me that the hose and / or pipe is a road draft tube, it relieves crankcase pressure. Your engine is pre- smog and road draft tubes were necessary as were open filters on the oil filler tube.

Thanks NTFDAY, I figured that the fuel filter was not suppose to be compleatly full but, my dad thougt it was so, I figured i'd make shure. I thought that thing on the side releaved crankcase preassure but, didn't know what it was called.

Matt
Glad to be of help. Youv'e got a nice ride. My step-father had a similar one in the mid 50's

Matt167, Sounds like the same problem I had with my ranchero.
I thought It was vapor locking when it was really a venting problem. The car ran fine at 30 to 45 MPH but If I went faster then that the car would die. It was creating a vacuum in the tank. Ends up the vent tube was pluged up. I had tried to leave the cap off the tank But the fill tubes {ONE HOSE IN ANOTHER HOSE}where collasped on each other. I guess they would'nt let the air in to the tank. I had Replaced the fuel pump, all the filters which there was three and thats not counting the filter in the carb. All the fuel line from the metal tube on the frame to the fuel pump then to the carb. The filters did make me think that the last owner was trying to fix a problem too. Hope this helps you, dont know if you have the same problem or not.

Huh, when we drove the car down to my grandparents, it was running fine at 30 MPH, when we opened it up to achive 50 MPH, it did it for a while but we backed off the throttle cause we diddn't want to have a blow out ( badly weather checked rear tires ) and then the car started to die, we had to pull the choke all the way out to keep it running, pulled the fuel filter off, blew it out and there was stuff plugging it, ran fine after. We have not had any sediment problems since and we haven't ran it past 40 MPH since ither, that makes me wonder if a clogged filter was the problem, when we pull the filter off there is always preassure behind it. Is it safe if I blow the vent out with air hose blow gun cause it's right inside the filler neck?

Matt
I'd check the fuel line all the way to the tank and you might have to pull the float assembly out of the tank and clean it. Could be the filter screen on the float assembly is partiality clogged and giving you the problem. If you do that drain the tank first.

Good question, I don't really know if you can do that with out hurting any thing or if it would even work. You better give that Question to some one else.

Matt, I'd take the gas tank out and have it boiled out at a radiator shop, then repaired if necessary, then undercoat it and re-install it with new lines (.375 Stainless brake lines w/brass connectors work great) to the fuelpump.. that way you'll not have a problem "down the road" for quite some time.. be sure that wherever they contact metal under the clamps that you insulate them with a piece of rubber or other non rusting material... I use home made polished aluminum "clamps" instead of them steel ones for the gas AND brake lines...

Sounds like a lot of work but, what has to be done, has to be done, gotta get the gas gauge working NE way and I probably have to drop the tank for that. Thanks for the advise. I got the exzaust most of the way on but, I diddn't get enough muffler clamps so I gotta get those tomorrow. The tank don't leak and we had it filled right up so gas was in the filler neck.
