Tony Cipponeri Posted August 10, 2009 Report Posted August 10, 2009 I am replacing my gas line in my 50 Plymouth, and I have a couple of questions. 1 What is the boiling point of gasoline at sea level? 2 Has anyone draines their gas tank via the rubber drain plug? I am afraid to take the drain plug out, for fear of not getting it back in right, causing a leak. Tony C Quote
Young Ed Posted August 10, 2009 Report Posted August 10, 2009 I have not seen any of these with a rubber plug. My 46truck 48 and 51 car all have metal plugs Quote
Don Jordan Posted August 10, 2009 Report Posted August 10, 2009 How funny you should mention this... I just drained my tank today. My tank has a drain plug on the lower right/rear of the tank. I have it up on stands and just put a 5 gal gas can under it. I'm taking my tank out to have it boiled out and coated. I was driving down the freeway and it just stopped. Ran out of gas. (with a full tank) I put in a new fuel pump earlier so it can't be that. The car has been sitting for over a year and I figure it's an old tank - could be crud inside. If that doesn't work... well it's gotta work. Quote
P15Mike Posted August 10, 2009 Report Posted August 10, 2009 I drained mine last fall . Mine had been sitting for 30 yrs , didnt have too much trouble removing/reinstalling it . Mike Quote
Tony Cipponeri Posted August 10, 2009 Author Report Posted August 10, 2009 Thank You Mike, was your plug rubber? Tony C Quote
DigmyP18 Posted August 10, 2009 Report Posted August 10, 2009 My car had sat for 7 years when I got it from the PO and the Tank was incredibly nasty inside. I got a process done called Gas Tank Renu by a guy in Apopka FL (closest dealer to me). It cost $300 but was well worth it as it seemed like my fuel was tring to go back to it's crude oil state. There was about a 3/8 inch layer of black sludge in the bottom of the tank and the sending unit had either been removed previously or was consumed by the fuel funk. Remove your sending unit and look inside with a flashlight. That should give you a pretty good idead of what you are dealing with. Quote
greg g Posted August 10, 2009 Report Posted August 10, 2009 I would think that the boiling point of today's gas is on the lower end of the spread listed in the answer. Everything I have read says it it more volitile than previous formulations, meaning more prone to evaporation, hence all the evaporative emission stuff on new vehicles. Because it is a soup of various chemical componants, some will evaporate before the boilinb point of the carrier is attained, So whaddy cooking???? Quote
Tony Cipponeri Posted August 12, 2009 Author Report Posted August 12, 2009 Hey guys, I replaced my gas line, and it no longer is close to my driver side manifold pipe, so I don't think it will boil gas again. As for the drain plug in the gas tank it is aluminum, and comes out easy and goes back in easy, no leaks. Tony C Quote
Ernie Baily Posted August 12, 2009 Report Posted August 12, 2009 Hi Tony, I'm planning on removing my tank on my 48 Ply to have it repaired. However about 18yrs ago I used a "Slushing compound" and it coated the internal filter/pickup. I then cut the tube to the intank pickup/filter and it works now, however when the gas level gets below the inlet on the side of the tank it runs out of gas with still about 6-7 gal in the tank. Have you or anyone else run into this ? Has anyone restored/replaced the intank pickup/filter? Can anyone recomend a vendor that could repair the tank and repair the intank pickup/filter? Thanks, Ernie Baily Simi Valley, Ca Quote
Young Ed Posted August 12, 2009 Report Posted August 12, 2009 Find the closest gas tank renu folks. They can fix it and its lifetime guaranteed afterwards. Depending on what all it needs it won't be cheap. Quote
DLK Posted August 12, 2009 Report Posted August 12, 2009 Find the closest gas tank renu folks. They can fix it and its lifetime guaranteed afterwards. Depending on what all it needs it won't be cheap. I used the gas rank renu dealer in Shakopee, MN and it was the best $275 investment I made in my 53 DeSoto. The tank was full of a ton of rusty crud before they started, and you can't beat the lifetime guarantee. Quote
Young Ed Posted August 12, 2009 Report Posted August 12, 2009 They did my p15 tank also. I think I came in right about that 275 mark too. I might have them do one for my pickup next. That'll probably be even more since the bottom is caved in. I think they must have aimed for the stumps! Quote
Tony Cipponeri Posted August 14, 2009 Author Report Posted August 14, 2009 Hey Ernie, When I drained my tank, I cut the fuel line also. When I was done I put 1 gallon of gas in it and drove to the station, to fill it up. So mine was picking up fuel with just a gallon in it. Tony c Quote
