Waynne the admin here and I would like to personally extend a sincere welcome to TorqueCars. I apologize for the delay in responding; I've had a really busy period recently, but I believe I've caught up now.

What's your budget and what are you aiming for?

I'm certain you'll fit right in, and I'm looking forward to talking cars with you.

Injector leak-off pipes should be replaced they can become porous. It's a cheap fix, and you'll have gasoline flowing again in no time. While you're at it, check to see whether the fuel filter needs to be updated.

To begin, you "always" begin with the cheapest options. Before replacing the fuel valve, the leak-off pipes and the fuel filter should have been changed. Once again, at the gasoline tank, an air leak might be caused by a corroded or porous connection or a rusted pipe.
