Gas smell?

[Chris1990gsx]

I smell gas while in boost. I'm thinking it could be a bad seal on the welbro 255 fuel pimp its making me run really rich, but not really sure. Has anymore had the of the similar problem.


Thanks

Another idea is it could be an injector seal gone bad, do a BLT to find out if it leaking. Don't want any engine fires.

I've done a BLT at 25psi no leaks. It's like i smell gas under the car.

Front or back of the car? I had a fuel filler hose leak gas.

Look up how to smoke test fuel lines. When your in boost, the fuel pressure regulator will raise the fuel pressure 1:1. So it's very possible the leak is intermittent and only happens when fuel pressure raises above a certain PSI.

Also check the gasket around the fuel pump hanger/sending unit assembly.

Is there any videos on how to do it. I'm dumb when it comes to working on cars

Pop the hatch and pull the carpet up. There is an access cover on the left side, see if you can smell any gas in that area.
