Alright everyone, I finally got my silversides mostly rewired, enough to try to show off a little and after about a two mile trip she stalls and won't refire. So when I look back over things I found several completely stupid things I had done and chalked it up to just that stupidity. This morning I decided to drive her to work so I could get some things done on her the next couple weeks. The trip is about 15 miles. After about the first five or so she kinda studder a little but kept running. Then about another three she studdered but worse this time, still kept running. Finally starting up the on ramp to get on I-75 she studdered and I couldn't keep enough speed to keep her going, she stalled and wouldn't refire. Called the tow truck, got a jump, off we go. She stumbled twice more pretty bad on once not as bad in the last three of four miles. I figure that since she sat at Easter's for about three years I may have some fuel system trouble. I put a new filter on her and cleaned the strainer out last winter and she hasn't been run more than 50 miles since. Do I need to change filters and drain the tanks, which are almost full? Can I put some fuel treatment in there and get by till they run a little lower? Do I need to also blow the lines out with air? Or am I totally off track and maybe I need to balance the tires or something  | ||

definitly sounds like fuel problems...try getting a gallon of POWER SERVICE...(in a white jug)usually at wal-mart or a truck stop...take your filters off,dump the fuel out,fill them with power service,put the rest in the tank... | ||

Thanks 2D, I got some last night but didn't have a funnel at the house to put it in with. Wish I had now. That 20 min trip wouldn't have taken an hour and a half. | ||

You may have water that condensed in the tank after the years of sitting unprotected. A hand pump with plastic hose or thin copper tubing that you can feed into the lowest corner will work. You can also have wrecked the injectors with out using the proper oil to preserve them. they have filters which could be plugged, or could just have gunked/rusted up. FAST FRED | ||

Nick, I would check the fuel pressure. Go purchase a oil gauge and a cheap gas fuel pump some hose and fittings to tap into the secondary filter Screw the gauge into a spare fitting in the secondary fuel filter. Take a hose and connect to the fitting that supplies fuel to the fuel pump. Put the other end in a bucket of fuel. When you try to start it hold it wide open till you are sure you have good prime. The gauge should read 20/30psi at idle 70 psi full thoatle. see how she runs and repot. The fuel filter is to attach to the secondary fuel filter ( not the primary you can damage your fuel pump ) if you need to prime the system. You should always have one. I,ll bet you have a line from the tank to the primary filter succing air. John | ||

Hi Nick have not heard from you for a while. Just something to check is the flexible fuel lines them selves. A common problem with a symptom such as this is the fuel line on the inside of the braid will become very soft. They then will cave in or be sucked in and close off during heavier fule demands. When the line is sucked close you of course run out of fuel and the engine stalls. After a brief time with out the engine running and the fuel coming to a rest the line will open up. The engine restarts and runs good until the line closes again. It becomes very frustrating. The simplest problems are usually the most frustrating. Good luck Nick and let me know from time to time how you are doing on the old bus. Tim | ||

Well I put the fuel system cleaner in her and back the smoke off by quite a bit when she fires up. Haven't had a chance to take her out again yet to really try her out. I do have a couple more questions though. I've got some other sort of issue with the fuel system. When she's shut off for an hour or two she won't restart without just a touch of starting fluid(I can almost just sit the can on the bumper and it will start). I'm guessing I'm losing my prime some how. I had thought it was the seal around the fuel strainer canister but I rebuilt the seal around it and it seals well so now I don't know where I'm leaking. I've spent two days cleaning the engine compartment and I can't find anywhere I'm losing my prime. I know I can put an electric fuel pump in the line but I'd like to fix the problem. Also (sorry for the lenght) today was the first time I've been able to get all the way under the engine to investigate my exhaust leak. Much to my dismay I have a baseball size hole in the muffler. Sooooo I need a muffler for a 6-71 in a 3751, any ideas? I'm emailing Luke after I finish here. Thanks everyone, Nick | ||

does sound like fuel line from tank...it will suck air.. | ||
