Gas leaking from hose that is under tank that is not for gas flow

replace the gasket under the pump /tank sender unti or hoses at the tank

check the point where the fuel hose goes to the fuel tank
there is very fine filter in the hose that could be blocked preventing full fuel flow
only running on choke indicates insufficient fuel flow

Hi Charlotte:
You'll need to determine the exact source of the leak:
- Failed hose? Replace it.
- Hose not tight on coupling? If there is enough slack, cut 1/2 " off end of hose and re-install.
- Hole in tank or coupling tube. Repair or replace.
Hope this helps.
Cheers.

1) you might want to check the fuel filler tube to see if there any rust, resulting in fuel leaking out whenever you filled the tank.
2) check the fuel tank fill-up hose (sill hose) might have a hole- causing fuel leak when filling up the gas tank.
3) you might want to contact your dealer, there was a recall regarding the tank filler pipe and cap problems.

I have a 2001 Sukuie Morauder 800. I have had leaking gas under the motor. The rubber tubes from the gas tank to the carubater needs to be replaced. With age the gas wareouts the rubber on these tubes.

check and see if there is still a leak when you are not putting gas in it if it is still leaking, lower the tank and check all the hose connection for leaks. replace hose and clamps turn key to run but not start with tank lowered look for leaks

If it is coming from on top of the gas tank, then you will need to inspect the fuel pump plumbing for a leak. It may be as simple as replacing the rubber gas lines.

My 1997 Rodeo had a leak coming from on top of the tank. After checking it out with a flashlight and a mirror, I discovered that the metal tube that runs down into the tank had rotted. Unfortunately, the metal tube was part of the fuel pump assembly and the entire fuel pump had to be replaced.

You can expect tp pay about $350 for a fuel pump from Autozone. I found one on Ebay (used from a junk yard) and replaced it myself for under $50.

Before you buy anything, make sure you identify the source of the leak. Like I said, it may just be a hose replacement.

DTC P1455 - Substantial Leak or Blockage in Evaporative Emission Control System

The PCM monitors the complete EVAP control system for no purge flow, the presence of a large fuel vapor leak or multiple small fuel vapor leaks. The system failure occurs when no purge flow (attributed to fuel vapor blockages or restrictions), a large fuel vapor leak or multiple fuel vapor leaks are detected by the EVAP running loss monitor test with the engine running (but not at idle).

Check this possible causes:
After-market EVAP hardware (such as fuel filler cap) non-conforming to required specifications
Disconnected or cracked fuel EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube
EVAP canister purge valve stuck closed
Damaged EVAP canister
Damaged or missing fuel filler cap
Insufficient fuel filler cap installation
Loose fuel vapor hose/tube connections to EVAP system components
Blockages or restrictions in fuel vapor hoses/tubes (items also listed under disconnections or cracks)
Fuel vapor control valve tube assembly or fuel vapor vent valve assembly blocked
Canister vent (CV) solenoid stuck open
Mechanically inoperative fuel tank pressure (FTP) sensor


Check for audible vacuum noise or significant fuel odor in the engine compartment or near the EVAP canister and fuel tank

Tell us news.

I'd check the clamps on the filler tube hoses. Also check to see if they are kinked, especially the small hose.

I my friend have a question for you...
Did you top of the fuel tank after your last fill up?

It might be your fuel over flow tube under the bike,
that the smell is coming from.
It is designed to discharge the overflow safely
on the road beneath you...

Check it...Good luck.
