Default How does the WRX fuel pickup behave?

What is the minimum fuel needed in the tank to prevent starvation in long sweepers? How about in rapid transitions such as slaloms?

I ran 26 AutoX events last season. I only had fuel starvation once after I had been running a couple runs with the Empty light on. It was always on a tight left turn.

So, I'll guess that most everyone will be safe as long as they keep off the light.

I will second and say that as long as the light isn't on you won't get starvation. It has a higher threshold than alot of other cars.

Nationals... 2 gallons for 3 runs. No Starvation.

If you can get it where the light just comes on for 3-4 60 second runs, you'll be fine. It's simply amazing if you ask me.

Thanks for sharing the information. I know we would have figured it out after a few events but it helps to not start with so many unknowns. My wife and I are going to campaign the WRX heavily (DS) this year and go to nationals if we don't embarrass ourselves at the divisionals and national tour events. Glad to hear the WRX does well will little fuel. I thought I was spoiled by the Miata, which due to an unusual shaped tank will autox with about a quart of gas.

I know a lot of locals in Houston that had problems with anything less than 1/4 tank. I personally had many runs close to E or with the light on and no issues. One thing to take into account was the regular track has many undulations for water drainage which may lead to more starvation problems than one would normally expect.

I'm jealous of all you folks who are not experiencing fuel starvation at low levels in the gas tank! I consistently encounter this problem if I'm taking a long right hand sweeper aggressively and I've got less than 1/3 to 1/4 tank of gas. It's such a bother and concern that I'm gonna do a fuel reservoir ("surge tank") setup sometime soon. But, maybe I need to get the shop to take another look at the upgraded fuel pump installation in the tank.

Drive smoother instead of jerking the wheel. Hehe.

I usually start an autox with the light. Never has a problem.

Keith,

Thanks for the advice

But, seriously, this is good to know, that it's not really an issue with the WRX. That gets me going on the right track (pun intended) since my issues may be more to do with the Walbro GSS341 pump and/or the installation particulars

GoodFinder,

it DEFINITELY has to do with your fuel pump. jmott couldn't run at AutoX's with less 1/2 tank to start.
