Is it carbureted of fuel injected

[Farmer Jamie]

Hi fuel injection
also engine idles abut 900. Rpm strong smell of fuel but engine seems to run fine just got it running of hose in my shed
any help with this would be great

Sounds like it's getting too much fuel. I'd check the fuel pressure on the rail or just go ahead and install a new fuel pressure regulator they are cheap enough and see if that helps.

Might want to replace the filter as well.

[Farmer Jamie]

Yeh think your right ordering new fuel regulater also think I'll replace vacuum pipe coming out the top of it just in case it's perished.Does anyone know if there is a cold start sensor on gt 40 EFi? Will check filter cheers.

You may want to check fuel pump relays and connections I recommend dielectric grease on marine electrical connectors. I have replaced them along with fuel pumps on these engines with fuel cell. pretty common with the gt40.

[Farmer Jamie]

Will do thanks
