i have gas leaking from the float drain bowl. i have done the following and still leaking.

1. cleaned the carb and checked float level and needle(checked fine)
2. cleaned the carb again rechecked everything and put in line filter on
3. replaced the float bowl drain screw.

still leaking just when not running. turn off the fuel valve and it stops.

anymore opinions or just turn off valve when not running.

thanks

 

Must be the day for gas leaks,I have the same problem, just started today and gas all over the garage floor, where did ya find the shut off? I have a 1998 454-4x4. I have ran into the same problem on a generator, fornd its best to just shut off the gas valve

 

i think on 454 it is up and under the right side plastic panel

 

Thanks, I'll go out and take another look, just bought this and not familiar with it yet

 

Found it, thanks much, must be a common problem with these. its like a motor cycle, shut off, reserve, on. again thanks for your reply

 

did you check if the float was any good or not? hold it underwater for a few seconds then take you hand away, see if ther is any water inside the float

 

If the fuel is leaking out the drain tube at the bottom of the float bowl then the screw is not seated all the way. If it is flowing out a weep hole on the side of the carborator then the float is sticking open for some reason. (bad float, faulty needle seat or needle or some junk stuck in it) It could also be leaking from around the seal on the float bowl.

Also, be careful to not let it leak into the cylinder because if your intake valve is open slightly then fuel can run into the cylinder, around the rings and mix with the engine oil. This can cause engine damage if you are not careful.

it is leaking from the nipple that you attach a tube to on the bottom of the bowl. took it all a part last night around 9 pm.
did not start leaking again till around 3 pm today.

have put a new drain screw in already

 

The only way for fuel to still be coming out of that float drain is 1) the screw is open 2) your float is not shutting off 3) your float needle is shot

Soound slike you have a very slow leak which would explain why it takes a while to leak out.

If the is a visible discolored ring at the tip of your float needle, it needs replaced.
The float arms should be parallel to the float body (will get you close enough)
Also the metal plunger on top of the float needle that the float tab rides on wear out over time, and will not be as long as it use to be which will cause a leak, a slow leak.
Same goes for the float tab, that sits on top of the plunger on the float needle, it will wear out (smoothen the punch out) and cause it to leak slow to.

 

going today to pick up a new float and needle. it this dont work i will just have to keep the gas shut off while it is not running. dont know what else to do if this dont work.
