You compressor may have an unloader valve at the tank. This valve acts as a check valve allowing air into the tank and then when the compressor stops (you would normally here a pssssssss sound if the valve is working) the valve allows the air in the compressor to escape. This makes it easy for the compressor to spin up the next cycle before it sees any load. You can try and clean the valve, but I would just buy one from grainger.com since it is probably bad. Search for unloader and note the the first size is the tube OD.

Whats causing there to be no fuel coming through lines and car just dies out when driving?


Do you have fuel pressure? unhook your fuel line and see if the pump is doing its job...could be a clogged fuel filter or a fuel pump.

Loss in oil pressure screamin egle 103 2006


On SOME of the Harleys with the oil tank mounted below the transmission, the oil feed line needs to be "bled", so the oil pump doesn\'t "cavitate" (suck air).
Unhook the oil feed (not return) line at the engine, and allow some oil to flow out (removing oil fill cap helps) to get air out of line.
Replace line and try again.
Also, if you didn\'t pour some oil into the filter prior to installing it, it will take a little time for it to fill (AFTER the oil runs through the engine)

Connecting the compressor to a tank


You left that question rather vague. Are you asking what material? or What size? I normally would run one size larger pipe size than the outlet on the tank, unless the distance is great. You would connect to the tank outlet which is usually 1/2 way up the side of the tank. Use only black iron or copper pipe, plastic pipe is not strong enough for compressed air. There is some plasic tubing rated for air, but that looks sloppy and isn't inexpensive eitehr. Also put a "FRL" between the compressor and piping (FRL=filter regulator lubricator).

I have a 2003 huskee rear tine 5.0 when i spray starting fluid in it's runs 4 a few seconds then dies. I have cleaned the carb and the gas tank and line, I still seems that it is not getting fuel


Did you clean out all of the tiny holes in the main jet of the carburetor? I assume you also put fresh fuel in it as well. One other thing, a compression leak (loose spark plug, bad head gasket) can make it act like it's starving for fuel. Good luck. I'd still place my bet on the carb having one or two holes plugged in the main jet.

My air compressor motor runs until I put a load on it. It only can get up to a few psi then dies. Is the motor bad or the Capacitor?


could be many things th the other is a bad motor, if it's first is the motor starting capactor, the second one is the check valve that keeps the pressure from the tank from reversing to compresser head.

Tank starts to fill then motor stops


disconnect line out from the compressor, run unit for about 5 to 10 min. if no problem. I would say that your tank valve is in wide open. replace it. the valve must close on ever down stoke so air don't feed back. this valve is screwed into your tank at lines end- good luck

Will not pressure up even though it runs and runs and runs


Check for leaks of course... THEN check the check valve AND the Compression Relief valve which is OFTEN cintained in teh pressure switch. This valve bleeds the compression left in the head so the thing can restart without a pressure load. This is a small pintle that closes when the pressure switch starts the compressor. The check valve is the other thing and it is often a part of either the head or the pressure line to the tank at the tank.

Car Dies suddenly, May **** and jump at constant speed,


what is the year mahe and model of your jumpy jerkey car? is it throttle body injection carborated ot electronic fuel injection ?have you taken the fuel rail or line loose and tried blowing it out with a strong blast of compressed air ??if you changed the fuel filter and it was dirty and you say you changed the tank and fuel pump you more than likely
are experiancing what they often refer to as butterfly action in your fuel line or your injectors are plugging up sounds to me more like a piece of rust or something of that nature doing a little gate or butterfly trick on you .. a single piece of rust can cause trouble for years if it is big enough and in the right position in the fuel line.. take your fuel line loose at the tank, both ends of the filter and the injector rail and with a strong compressor blow backwards through the fuel line,both from the engine to the filter end and from the other filter end to the tank (caution ) ( caution ) do not i say do not blow compressed air backwards through the fuel pump you will blow a hole in the diaphram and ruin the pump adding to the expense or your repairs dramaticly..
if that dont do the trick my next suggestion would be get the code connector fixed and get a good reading on the computer ..one more thing how good are you with elictrical ? it could be a short in the ignition switch or wires going to it keep me posted we will try to get it sorted out for you good luck and i hope this helps

Hi ColdinSF,

You need to remove the covers from the unit and blow out the gas lines with compressed air. If you can remove the gas lines blow out the lines and what they connect to like the pilot light and main feed line to the burner. Usually they gunk up with use and just need to be blown out with compressed air to clear the lines again. Maybe you have some dirt or foreign object from your gas tank which has clogged the line. Also check the igniter electric lines as well and make sure everything is connected properly. Especially make sure you tighten the gas lines you remove. Hope this helps.

Regards
Bryan
