Bobtjr(dale) Posted December 17, 2009 Report Posted December 17, 2009 Guys, tonight I was by myself and had a two man job. We had the gas tank off the coupe clean and sealed the tank. However the fuel lines are a different story. They do not blow rust through but are still gummed up. Also the fuel pump is a little weak. If you don't start the car often the pump loses its prime. Well, I waited too long and could not get gas to the carb. When this happens I usually have someone else pressurize the tank while I crank the engine. Tonight I had no help. I have an air opperated vacum pump for air conditioning. The cheap one from harbour freight. It really works well! I unhooked the fuel line from the carb and slipped the hose over the vacum and after about 15 seconds I had fuel! Hooked the hose back up to the carb after the bowl filled back up it fired right up. Its definately not rocket science, but it sure worked quickly. Most importantly you don't have to worry about putting to much air pressure in the tank and causing a leak. Just thought it might help somebody else Dale:cool: Quote
1955 plymouth Posted December 17, 2009 Report Posted December 17, 2009 thanks Dale. I think we all appreciate any little ideas that could prove usefull in the future, also I think this stuff if nothing else reminds us to think about how something works mechanically and figure out how to adapt and overcome the obstacles.

Young Ed Posted December 17, 2009 Report Posted December 17, 2009 Now when are you fixing that weak fuel pump Quote
Jim Saraceno Posted December 17, 2009 Report Posted December 17, 2009 When I rebuilt my fuel system I used one of those hand vacuum pumps to get the fuel to the carb... Quote
pflaming Posted December 17, 2009 Report Posted December 17, 2009 Fuel tank is next for me. I have a nice clean one. How did you clean the fuel line? Mine has sat for 20 Years, (plow sand through it)? Quote
Young Ed Posted December 17, 2009 Report Posted December 17, 2009 If I had any issues like that I would just replace the line. Enough line and fittings to do an entire car or truck is under $20 and its well worth it to run new instead of messing with old stuff. Quote
Jim Saraceno Posted December 17, 2009 Report Posted December 17, 2009 I had an issue where my fuel line rusted through, sucked air and sloughed off enough rust to clog the fuel pump. I replaced the fuel line with new brake tubing, added a fuel filter close to the tank and another smaller one just before the pump. If your line is clogged I would just replace it. Quote

I have bigger issues to deal with right now, if have not seen the pictures my coupe is the one that the tree fell on. I am in the middle of 33 ford sedan delivery (flower car) that I am painting to make money. My car has to sit outside in the freezer at this point. I just start it every so often to keep her going and drivable. I have the top pushed up now, and have it almost cut off. I have a top from a doner car. sorry going ot the tanks has been done, and yes the fuel line will come next. dale ps. this ain't my first rodeo:o Quote
BobT-47P15 Posted December 17, 2009 Report Posted December 17, 2009 We removed the gas tank and cleaned it out about the same time the engine was put in the coupe. Did not replace the gas line as it seemed to be working OK. The fuel pump might be a bit weak....not real sure about that. Have another one waiting that can be installed. Along with another carb as well. The car had been sitting for some amount of time as the last owner had removed the engine. But I think the guy he got it from had not driven it for a while due to both engine condition and brakes. The tank was real gunky - took a while to get a rod thru to it. He's just trying to keep it started every few days during this cold weather. I had bought a new battery for it from Atwoods Farm Supply...which ran down rather qickly. Took it back and exchaged for another, which so far seems to be better. Always something with these oldies but goodies. Also fiberglassed top of the tank which had pinholes. Quote

norrism1 Posted December 19, 2009 Report Posted December 19, 2009 I just poured small amount of gas down carb throat. Runs long enough to pull gas from tank to pump. Quote
Norm's Coupe Posted December 19, 2009 Report Posted December 19, 2009 I just poured small amount of gas down carb throat. Runs long enough to pull gas from tank to pump. That's what I've done in the past. Just use an aerosol can lid, fill it about 3/4 of the way full and dump it into to the carb. Get in the car, hit the button and it starts right up. Quote

Just use an aerosol can lid' date=' fill it about 3/4 of the way full and dump it into to the carb. Get in the car, hit the button and it starts right up.[/quote'] In this case thats not an option. The first thing I tried,was similar to that. I have dumped raw gas in the carb before. I have seen a motor backfire and then proceed to catch on fire! What I prefer to do is fill a turkey baster with gas, and then fill the bowl on the carb by means of the vent tube. ( If any one is wondering is the diagonal tube that sets in the throat of the carb) Once the bowl is full it will sit there and idle for a few minutes. Since the carb is doing its job there is no chance of backFIRE. My fuel system is sucking some major O2 somewhere, wheter its the pump or the carb or the fuel line that remains to be seen. The one thing that I do know if I start it daily its fine. ( weird huh ) Dale Quote
Norm's Coupe Posted December 19, 2009 Report Posted December 19, 2009 Bob, I've never had one shoot flames out he carb doing it the way I mentioned by just using gas. But........I have shot flames out of a carb at least a couple feet high before. That was a little different case though. It was also in a new car that was no more than about 5 months old, back in 1972. Had a 72 LTD company car and parked outside all the time. One morning when it was about 65 below with the windchill, and about 50 below temperature it wouldn't start. Didn't pour gas down the carb, just lots of ether. That did the trick too, got the car started.:D As the saying goes, "no guts, no glory". Quote
Plymouthy Adams Posted December 19, 2009 Report Posted December 19, 2009 little gas fire in the carb throat..just keep turning the engine..it will get sucked into the chambers..not a problem ever...but of course if you don't understand this by all means please don't prime your carb... Quote
Don Coatney Posted December 19, 2009 Report Posted December 19, 2009 Early in High School I worked at an automated do it all car wash. I was always envious of the guy who got to drive the cars out of the wash tunnel to the finishing area. One day there was a reasonably new Corvette that came thropugh the wash. The guy got in and attempted to start the car and drive it out but the engine did not start. It just popped through the carburetor a couple of times. As was the practice at the car wash when this happened they would muster up all us boys to push it out so as to not slow down the line. So we are pushing this nice clean shiney Corvette out when I happened to see a big bubble appear in the center of the hood. The carburetor had backfired and was still on fire melting the fiberglass hood. Quote

When I was a a teen my bud had a big block chevelle. He decided to put a huge intake with double carbs and electric fuel pump. Well he got the dist. 180 out of time. (well we think thats was the problem the car burned to the ground) He got the wise idea to pour a bunch of gas down the carbs it backfired and with electric pump and two 850 double pumpers with all four bowls full it ignited, and burned the car. The electric pump was at the tank so it kept pouring fuel to the fire. After that I learned my lesson. With an old car unless you really know your motor inside and out, a timing chain could have jumped time. ect... It's always better to be safe than sorry. By the way only if it decides to run, will it suck the fire in the chambers. Its a little thing called vacum. If you fill the bowl on the carb, your carb will do its job. The orginal problem was not getting fuel to the carb I filled the bowl it ran a couple minutes until the bowl emptied. It still did not pull fuel through the line. I had to prime the pump by sucking fuel through it. Yes, I need to replace the line, rebuild the pump, and maybe rebuild the carb. But right now I have running enough to move it around the shop until I get the new roof installed, and do the body work. I am an A.S.E. certified mechanic, and this ain't my first rodeo. Quote

dezeldoc Posted December 19, 2009 Report Posted December 19, 2009 Thats why you keep a rag handy, carb on fire smother it with the rag and done, fire out. i do always fill the fuel bowl but also put some down the throat to help it out, never had any issues.don't forget it it is sucking air in it is also a place for it to leak out fuel when not pulling gas through it.
