Lynda,
Many times the return hose is routed thru the hole you described with no extra fittings or grommets. I suspect the hose cracked at that point, some of it fell inside the tank, and the rest is what you can see on the outside, so you may need to replace the hose with a longer one. The diameter needs to be larger than the hole as the ‘press-in’ fit seals the tank from leaking.

The operation of the primer bulb is quite simple. When the filled bulb is squeezed, the pressure closes the inlet valve and opens the outlet valve which then sends the fuel supply to the engine.
Priming involves delivering high-pressure fuel directly into the fuel system. This ensures that the entire system is pressurized, lubricated, and all air pockets are “bled” from the system. There are several options for achieving the kind of fuel pressure needed to properly prime a diesel engine.
The purpose of the primer pump is to pump sufficient fuel from the supply tank to the engine and particularly to the injectors of a diesel engine to enable the engine to be cold-started without excessive use of the electrical system which normally operates the fuel pump.
ANSWER: The primer bulb, which is located in the fuel line between the gas tank and the engine, is used to fill the carburetor with fuel when the engine is started cold. The rubber bulb resembles an oblong ball. Inside the bulb are two valves that open and close.
Gas models that start will a pull rope include a primer bulb to deliver a gas and air mixture to the carburetor to start the engine. Primer bulbs that have cracks or tears in them need replacing to start a gas leaf blower.
Marine fuel primer bulbs are available in three sizes for 1/4″, 5/16″ and 3/8″ inch fuel hoses.

Which fuel line “port/inlet” on the Walbro wt-380 goes to the fuel tank? It’s on a Craftsman 25cc Gas “Weed Wacker” Line Trimmer purchased in 2002. It has Walbro WT-380 carburetor with external primer bulb. The carb has two inlets for attaching fuel lines – one to gas tank, one to primer bulb. One inlet is on diaphragm side of carb (side with the two Low/High speed adjustment screws). Other inlet is on “reservoir?” side (side with air/fuel mixture screw). Which inlet gets the “fuel tank line”? (Other will obviously go to primer bulb. I found all kinds of diagrams on web but none that showed this. Your assistance is greatly appreciated. (Problem occurs when replacing gas lines and forget which line goes where:)
ANSWER : Usually the line with the filter on it that comes from the tank goes to carb. inlet first which is most likely close to the bottom side of the carb.nearest to the engine,then the outlet or return line on the carb.goes to the inlet side of the primer and the outlet side of the primer goes back to the tank. The primer draws fuel through the carb to the primer to the tank if its not? then correct the line connections until it does

Primer bulb will not take in the fuel in it seems block
ANSWER : A fuel system inspection is needed here. You need to check the intank fuel filter,(make sure its not clogged) the condition of the fuel lines,(soft, not brittle with no tears or cracks) ,the ventin the gas cap,(little rubber tube must allow air in). Foremost, check the condition of the bulb itself:sets in (primer base assembly) that has very small check valves inside it controlling the inflow and outflow of fuel. There cannot be any air leaks as the bulb on the carb and one mounted remotely from the carb depend on a vacuum effect to operate correctly. So some disassembly and acute inspection will be required.

How fuel lines hook up to primer ball – Troy Bilt Tb70ss Gas Trimmer
ANSWER : The supply line coming from the stone filter goes to the short nipple on the prime bulb and the line out from the long nipple on the priming bulb goes to the fuel nipple on the carb that is the closest to the muffler. The return nipple is the closest to the choke and it goes back to the hole in the tank that is the higest. I hope that helps.

Have a craftsman 16″ chain saw 358.360260. Could not initially get it started after it had sat for a couple years with fuel stabilizer in it. When I went to use it the fuel had all evaporated and the fuel pick line was rotted. I replaced that with some difficulty but finally got it on. Saw still wouldn’t start. Replaced the fuel filter. Still wouldn’t start. Pulled the carb apart and cleaned and recleaned everything. Diaphragms were good and I didn’t adjust any of the mixture screws because as I said it ran fine before storage. Non of the carb passages were clogged. Fresh gas 40:1, good spark plug and good spark. Airfilter is good. Engine has maybe about 4 hours of total run time on it. It’s a ZAMA (?) carb. It will run for about 30 seconds when I manually prime it by pouring a small amount of fuel directly though the carb. When I was disassembling the carb the vent hose that goes back into the fuel tank seemed to have a small out of ?substance? in it which I cleaned out. It was right at the end the of the hose that goes back into the fuel tank and not up by the carb. It didn’t appear to be like your typical gummy deposits/varnish though. I hope it wasn?t some type of spongy check valve stuff that is supposed to be in there. That might explain some of my problems. Anyway, I also can not seem to get the primer bulb to fill. When I open the fuel tank, look in side and depress the primer bulb, air bubbles come out of the fuel filter. But when I let the bulb reexpand there’s no fuel that gets sucked up the hose. I can however seem to fill the primer bulb when the fuel tank is full and the chainsaw is laying on it?s pull cord side and the bulb is depressed a bunch of times. The saw will also start and run again for about 15 seconds then die. It’s definitely not getting/fuel and probably running out . Thanks.
