Hey guys,

I took the truck to my place in Maine where it will be in a few parades in the next few weeks then I will drive her home.

She made it 98 miles before exhibiting some small attitude issues. The only way I can describe it would be to say she started to gag. I had driven about 50 MPH for first 50 miles then on to the smaller roads driving 40 to 45 mostly. Just around the 98 mile mark it started to gag. (run,gag,run,gag,run,gag) I pulled over in a gas station (I felt very lucky that of all the miles of nothing we had driven she decided to gak 50 yards from a gas station)

I was puzzled as she was idling fine temp, oil pressure, and other gauges were fine. I thought I was out of gas. But I was not.

It stalled out when I pushed it down to low idle. I restarted and it seemed to run fine. I started back on the road and it ran fine for a while. This happened a few more time but if I pulled it out of gear and revved it up I would be fine again for another mile or 2.

My thoughts were this is fuel related. When I got to my house I pulled the fuel filter and replaced it. (There were some tiny black flecks in it which look suspiciously like pieces of the rubber line leading to it.

It was better after that but still suffers these random fits of rev, gag, rev, gag.

Is this carburetor related? Maybe fuel pump?

Anyone ever have this happen to them???

Thanks
Rich

sounds like junk from the tank causing fuel starvation, maybe got some into the carb, might pop the top and see if there's any sediment in the bowl

Bill,
The tank is new and the lines are all new. I replaced the filter last year. I have never been happy with the current carb.

I could not kick it down to low idle. Carb was acting weirder than usual. Does this jive with some junk in the carb. I am at a loss as to how it would get there. Like I said everything but the carb is new.

Rich, I once had a similar issue with "tiny black flecks" in the carb, but they came from the rubber line AFTER the filter, in my case.
Good luck.
Fabio.

do you have a filter in the carb where the fuel line hooks up. my 2g has a small screen type filter there. it could be clogged also

yes...the truck has a more modern fuel pump (not the origianl glass bowl one) it has an in line filter just before the carb.

I replaced the filter last year but I don't remember replacign the little hoses that connect the filter to the steel lines.

I'm thinking if these are not true fuel lines or if they are just old they could be disintegrating into the fuel. If I saw little black flecks in the filter then there could be little flecks int he carb fromt he line that comes after the filter.

I will pop the carb off and clean it and replace the rubber lines and see what that gets me.

Too bad the truck is so far away....I miss her already and can't wait to go back this weekend and tool around!

sounds like the lines breaking down to me. get the high pressure fuel lines, they are a lot better material and will last quite a long time, and will hold up to moisture/ethanol/gasoline.

will do thanks

Also remember that the regular black fuel lines and such are attacked by heat. I located my fuel filter under the cab just outside fo the tank, that way I have "clean" fuel from the tank outlet through the rest of the system.

I always wondered about the fuel filter 5" above the exhaust manifold. My 49 3100 came with a carter filter/strainer mounted to the inlet of the W-1. It get's hot. I think it makes percolation worse. But it looks good and I can see it easily.

That is a good point. I am comtemplating replacing the fuel pump with a dual action pump (vacuum/fuel to help my wiper issue)and then also replacing the fuel line from pump to carb.

I woudl relocate the filter under the cab as you suggest.
