tired, tired, tired of gas leaking when refueling
 
I've tried all kinds of different angles, Ive tried the radiator hose in between the nozzle and the neck......how do I stop leaking gas everytime I refuel? Is there anyway to stop it,maybe install a flange so it fits just the nozzle in like newer filler necks?

Haven't really heard of this being a problem before unless it's one of those goofy pump nozzles that don't work unless you are pushing the spring loaded rubber cup back.

Are you trying to run the thing full pump speed?

I never use the auto fill handle mechanism. Always keep the trigger squeezed myself so I can control the flow. I don't trust the things to shut off either. With 1/4 to 1/2 squeeze on the trigger I've never had a problem with spillage on any of my vehicles, trucks, cars, classics....

Even when I set it so it can go as slow AS POSSIBLE, it will still dribble some out down the side. Good thing I dont have good paint yet. It did it before I replaced all the rubber lines to include both at the filler neck and it does it a little more now. I have dual tanks and it does it both sides. I have seen the complaint before but I'm fed up with it.

Re: tired, tired, tired of gas leaking when refueling
 
Wow, doing it on both tanks is odd. I have dual tanks on my 79 and haven't had this issue with either. Since it's both sides it makes me think it's something other than the vehicle? Having a kinked hose on both tanks is rather unlikely (I would think)??

It has to do CA vapor recovery nozzle design - they do not reach far enough! To fill my tanks I turn nozzle horizontal facing to the back of the truck, shove it all the way in and go easy on fuel delivery. Takes a while to fill 20G tank, but no more spills.

yes, that way I get LESS, but still enough to dribble down the side. Just barely enough that it evaporates as it tries to make a drip off the bottom of the truck. FRUSTRATING.

Indeed, I had to switch from 90 deg bent fuel filler hose to 45deg to keep fuel flowing down. It helped a little bit, but not too much. The old inlet port has a large diameter that one would think would help with fuel flow, but opposite is true.

Yes, the darn CA gas is very skunky - I can attest that refueling is a PITA!

Which style bed do you have if you have 76 and below with exposed caps good luck I'm changing from that style now to the newer setup with fuel door so hopefully all will be better after

Re: tired, tired, tired of gas leaking when refueling
 
Ive had this problem for about 8 years. The gas attendants would always set the auto nozzle on and gas would just spill everywhere. Now I just do it myself. I dont think its that bad but u gotta get the angle right and not go full throttle on the pump. If there is a fix to this i'd definitely be interested!

Square_78 06-20-2012 06:08 AM

Re: tired, tired, tired of gas leaking when refueling
 
Ive never had a problem filling the tank on my '78. where is the gas leaking from? Is it coming back up from the filler neck? Is there a breather line or something on the top of the tank that might be plugged? I have never had a problem with mine...

Do you have the tank vent and fill tube vent connected?

Re: tired, tired, tired of gas leaking when refueling
 
To the guys from east coast and Canada - the problem is with California mandated (CALIFORNIA AIR RESOURCE BOARD = eco-gestapo) nozzle design. It is simply too short for older trucks. Add to this a vapor recovery sleeve that compresses within couple of inches of fuel neck engagement and you have perfect spill waiting to happen. Over the years I have replaced, tanks, fuel filler hoses, vent hose and necks - nothing seems to work. However, when I used old style filler nozzle problem miraculously went away.

Correct. I deal with these when we frequent California. I had briefly mentioned it in my first post when I mentioned the goofy nozzle designs will sometimes cause problems, but the original poster didn't mention what style of pump he was using so I could only speculate.


I found that when using those, I have to manually pull back the vapor recovery sleeve with one hand so the pump activates, and pump with the other hand. Real pain in the butt, but it works without spillage.

I find it's easier in my truck because you are standing up while filling, and have plenty of room to mess around with the vapor recovery sleeve. Where it's a real pain is when I'm filling up my 70 formy or 72 chevelle where the fill neck is behind the rear pull down license plate, and you have the bumper that you also have to deal with, all while you are squatting down. You almost can't even get the short nozzle into the filler neck "AT ALL".
Luckily when that spills it winds up on the ground and not my paint. So much for the EPA regulated pumps that are supposed to be good for the environment when you wind up with a gallon of gas on the ground :rolleyes:

you guys are right. Im talking about these crazy CA nozzles with the sleeve. I'll have to start trying to manually hold it back and see what happens. I can press as hard as possible and get the nozzle in there but some always leaks out.

:lol: Yep, I mentioned that in my first post. I was wondering if that was your issue or not. Didn't know if you were using them. I don't care for those things either.

Cut sleeve off with knife, remove, write FU CARB on the fuel pump in sharpie and pump fuel into tank unhindered. Problem solved. :D

Just kidding, never seen one. Sucks that you have such a pain when trying to get fuel, you'd think the price would be enough...

i got tired of this as well. I got a muffler shop to bend up some 1 3/4 galvanized tubing and took some radiator hose and ran the line to the bed and welded up a filler neck by the tailgate...works awesome!

Sounds like u Need the same attachment the new f150 trucks have for pouring a Jerry can into the tank, it's a special funnel u clip into the spot u put the pump nossle and it makes sure the gas goes past a vent in the filler neck that stops people from watering or suffering ur tank, might help by pass the filler neck and get it straight to the tank

A transmission funnel with it's long skinny neck works too ;)

I carry one in the classic cars when on long trips just in case I fill up at one of these goofy pumps.

Don't tell anyone, but when I first ran into this style of nozzle many years back I was in my 70 formy and simply couldn't pump the gas properly. My first glimpse of this nozzle and I was like HUH??? After 5 minutes of fiddling and spilling gas, I pulled out a pair of tin snips and modified the pump handle :lol: Shhhhhhh!! Now I just carry a transmission funnel with me if I plan to cross the border to California.

It's not those CARB nozzles... my '77 does the same thing here. It drives me nuts! No matter how slow I pump it drips down the fleetside.:cuss:

I'd say that's an issue with your truck then. I've driven my 79 fleetside all over Arizona and pumped gas just about everywhere and never have an issue with either tank.
