I have a 1949 3800 (1 Ton) and I had a petcock valve on my tank and I ended up taking it out because junk built up and clogged the valve so I wouldn't get gas to the engine. I went and got solid brass pipe and elbows. So I no longer have a valve under my tank. Hope this helps.

Do you have a fuel filter between the tank and your carburetor (maybe at the carburetor)?

I was thinking how nice it would be to be able to shut the fuel off on my '53 while I worked on the fuel system - it has no petcock, just a 90 with a 5/16 barb. I checked my '49 one ton parts truck and I saw that it has a fuel petcock below the tank. I don't know if it was factory - many hands have been in there. Tried it and it still works. Rather than risk taking that old stuff apart and making matters worse, I left it alone and found a nice little 5/16 shut-off at Canadian Tire. I installed it just after the tank outlet on the 53. I still reek of fuel while typing - but for the last time.

Well I'm just setting here being stupid this morning. Many of you have heard me whine and grumble etc. This rant at my self is because I put five gallons of regular gas in my 54'. Six weeks later have to clean out everything. Truck ran like *#@%. Sewing machine six weeks ago to a black fog and 4 of the six cylinders alternately waiting their turn to ignite. The fuel line is setting right there would a high quality pet cock valve work if I put it in front of fuel bowl? That way if I'm in a pinch if I can't find a blue pump at a WAWA on the road trips the antiquers go on in sunny damp Florida I can park it back in the barn and run all the gas in the bowl out.

Hello, Doc,

Sorry to hear of your problems.

Have you searched through the OLD ONLINE CHEVY MANUALS? [chevy.oldcarmanualproject.com]
That should give you plenty to read.

I use regular gas in all my old truck. I have never had problems.
My gas tanks were stripped and coated inside and out.
All my trucks had/have original style gas filters and rebuilt original Rochester or GMC carburetors

I use/used gas treatment over the winter
- in upstate NY - unheated garage - negative temps in Winter and 90+ temps in the summer
- in NC - heat & AC garage - between 50 degrees and 90 degrees

Doc, I like that idea. I run all of my yard equipment out of gas when I stow them for more than a few weeks and I also run non-ethanol gas. I do wonder if a mechanical fuel pump can take pumping up against a dead head for as long as it takes to run the bowl dry.

We need our experts to chime in.

Phak 1,you are so right. At 2 1/2 to four pounds max pressure I'm sure it would ruin the fuel pump. Rats! I would have to be at the tank . Probably ruin the pump also, rats x 2 tclederman thank you twice. Your recommended site will help in keeping me out of my wife's hair. I related this post to her she said a long thank you. Ed
