Goes to 12:1 at wot coming onto boost then starts running away. I got the missus to check the fuel pressure in the driveway while I held the launch control on and the fpr is working. Looks like I'll be looking in the tank. The Walbro 460 is about 5 years old and sat for a while (in fuel though) so it might be tired. Could have a leak in there too so yerp, better check. I just filled up recently and filled my two jerry cans with E85, so I'll have to buy some more jerry cans to empty some fuel out to get the tank out. Oh well, that's cars for ya. 3 Link to comment Share on other sites More sharing options...

It was fine a few weeks ago, so either the pump is failing or there's a leak from the pressure hose in the swirl pot. I was just looking into that pump you recommended so that might have to be the fix for now. Link to comment Share on other sites More sharing options...

It's been a while since I looked. Dunno how I'll go getting the tank out with the car on the ground. Last time I used a hoist and it was a pita then. Eh I'm sure I'll sort it out.
