I have a Remington 100. It runs normal until the fuel gets to be 1/2 tank or less. Then it takes a very long time for it to light. The fan runs and fuel comes out the front. When it does light a nice tube of flame comes out the front and the associated smoke. I've cleaned and gapped the igniter plug. What causes the delay in lighting? Once lit it runs fine

hello mary,
no car told at all. maker ,model , year.
the cluster warning lamp glows low fuel level.?
just keep tank full. based on miles driven until fuel gauge sensors is repaired,
if car is 20mpg, and 10 gallons that is what>? (example)
every 100 miles fill up tank is 1/2 full now.
running it dry will wreck the fuel pump easy
and be stranded , never fun that. hope not you; for sure.

Bad fuel pump replace it

i am not 100% sure the fuel pump is located on the top 1/2 of the tank so it need about 3/4 tank of fuel to breath.

Your best bet , take an have a fuel pressue an flow test done . If you think it's fuel related . I'm sure you probably don't have the tool's to do these tests. We test , not guess as to what could be the problem . If clogged fuel filter it wouldn't get any fuel an it wouldn't start an run at all .

Sounds like your float for your gas guage is bad

Similar heaters that use diesel have to routinely cope with the dye added to untaxed fuel, ditto similar heaters that use both fuels. Unless there was an excess of dye in the fuel you used the problem was probably a coincidence.

Dirt can be a big problem due to corrosion forming in the fuel tank caused by a relatively large percentage of moisture naturally in the fuel and the formation of condensation. Fuel is generally filtered through a fine gauze when the tank is filled but there is little or no filtration preventing dirt already in the tank from being picked up and finding a way into the spray head which generally jams the spinner affecting the quality of the fuel spray.

Cleaning the spinner and nozzle might work for a while but only a major clean out will restore reliability until the next time. It is also wise to check and adjust the pressure of the air pump.

install clear plastin line in the return from the injector pump, any air in the fuel means trouble, somewhere in the fuel system its drawing air , usually neat the tanks, but not leaking enough for fuel to leak

have your evaporative emission control system check.sound like you have purge valve solenoid not working or vent valve control solenoid.have it scan.to see which component not working..reason your gas tank expanding. your fuel vapor building up pressure.your purge valve and vent valve open allowing gas vapor from charcoil canister. to be burn in the intake manifold to be burn in combustion chamber.

Check your fuel lines. It is probably getting air into the system. Also check inside the gas tank to make sure the fuel pick up line is still attached.


If you need more assistance please provide an exact model number and I can better help you.

sound like fuel pump too weak.
