fuel problems
« on: July 31, 2005 - 07:23:11 PM »
i was driving my Dart the other day and it stalled out on me, acted like it ran out of gas. i put gas in and it started and ran a couple miles and stalled out again. After 20 minets it started again and i drove a mile to a friends house. i went to pick it up today and i had the same problem after 2 miles of driving. My friends dad used to have a Duster and said he had problems with vapor lock. I'm not sure if this is the problem or not. when i drove it today the engine never got over 130 degrees, however the fuel line does run close to the header (about 1/2 inch). It seems to be a fuel problem because we sprayed ether into the carb when it started to stall out and it would run again. not sure what the problem is, the carb was rebuilt with 200 miles on it, and also has a new fuel filter. I'm hoping that someone has had trouble with this as well and could give me some suggestions on what to look for. Thanks

HOLY CRUD!


get the fuel line away from the header!

that might be oyur problem., or, the fuel pump, but, I would say stay a min of 6" or more from your header with your fuel line!
OMG!

also look to see if the tank is pulling a vacuum and stopping fuel flow   take cap off and see how far you can go. There should be pressure (very light pressure when you remove cap) in the tank but occaisionally someone screws up the hose or check valves

Could be a weak fuel pump or a clogged fuel filter.

thanks for the suggestions. i put a new fuel filter on it (a clear one so i could see if i had fuel or not). when i took the old one off some very dirty gas came out of it (this filter was new 150 miles ago). when i put the new filter on i cranked the engine over and ran the fuel line out of the pump into a bucket until the gas came out clear. It didnt take too long but some very dirty gas came out. Once the filter was back on i took it out again, went about 1/2 mile and it stalled again. There was no fuel in the filter so we blew the line from the pump to the tank out, while doing that we found the inside of the rubber fuel line feeding the pump looked to be frayed, cut the end off and hooked it back up. It seems to have been the problem as i drove the car for 15 miles with no problems. I still need to clean the lines and tank out since some of the gas that came out was so dirty. i'm hoping that i can just pull the tank off and somehow rinse it out, not really sure if there is a procedure for that or if anyone else has done something similar. Anyway, also gotta check the brakes out tommorow night as the back half of the master cylinder resevoir has dried up twice now. Thanks again.

you might want to check the tank and make sure its not rusting internally. Leaving the rust will only lead to alot of other problems like carb and pump damage.

the tank is definatly rusting internally. i wasnt getting fuel to the pump again and we pressurized the tank and blew the line out with an air hose and got some small pieces of rusted metal out of the fuel line. so i think my best option now is to buy a new fuel tank. I looked at the paddock and they have one for 68-70 A bodys without hte evaporative emission control. What is this control and how do i know if my tank has it now and i need to replace it with one?
Thanks,
Steve

the evaopative emissio control was to contain gas fumes , most A bodys pre 70 had a vented fuel cap & no extra hoses connected to the tank to seal the veanting to a carbon canister or to the carb to burn off the fumes n

As i have just paid my college tuition i would prefer not to buy a new tank/fuel lines and sending unit. Is it possible to remove the tank and clean it out? it is rusting internally and a friends dad said that he had done this before, but not sure if it was rusting or just had junk in the tank.
Thanks
Steve

Yuu can go have it sand blasted or bead blasted then they will put a coat of something inside and outside of the tank and bake it so that it wont rust again thats what i had to do for my tank bc it had rusted internally.

 :iagree:

  You can't just clean out a rusted tank. You need some kind of coating in there to cover up the old rust. My tank has some kind of black rubbery stuff in it. I have NO idea what it is, but I thank the previous owner.  :grinyes:

I wish I could thank the previous owner for stuff done to the car but I cant thank them for anyhitng with the sahoe they gave me the car in well actually I can thank them for letting me keep the car in the family. And I havent a clue what they use to coat the tanks with either but I know it works and thats all that matters to me.

It is probably some kind of TANK-RENEW product.  I had the hardtop tank done about 15 years ago when I was unable to source a new tank.  A local radiator show sent it out for the job.  Mine is red on the inside and black on the outside.  Been this long with no problems but I will probably replace it when I do the upgrade to the car!!   :beer:
