Definitely. On Wed I'll tighten it and spend a few minutes cleaning.

Not sure what Mitsu's reasoning was there. The X tank and hanger design is different than previous Evos.

Won't know until Proving Grounds, which is my next track day. There's no way to drive the car that hard on the street.

What about somewhere like 494/394 intersection where there's cloverleafs on all 4 corners? Go there late some night and keeeeep going right! Or wait, is the problem supposedly on hard left corners?

The working theory is that the surge tank holds ~45 seconds of fuel and after 6+ minutes of the tank sloshing in all directions, the surge tank was able to be emptied. The car has been solid on the street for a while now.

WOT for 6min while braking and turning would be pretty darn tough anywhere else.

Have you ever done road course? Sign up, man. The more Evos the merrier.

If some of you guys aren't busy then you should come over to the short course and at least hitch a ride. It's some addictive shit and it's nothing like the street, imo.

I've always wanted to, but I can't afford it at all. The amount of work I would have to take off, and to get everything totally "safe" for the track would already me too much. Then there's the price of actually going to an event too. lol

I just hope you don't pay the money and time for a track day, and find out the issue is still there. Story of your car, right? :P

Good luck!

My solution for all of the silly bolts on the SSP undertray.

[mlomker]

Fueling system died on the way to work and I barely got it into the office parking lot. The 044 in the trunk is making horrible death sounds. I'm going to have to do some parking-lot troubleshooting later today but it appears toast.

Time to start using real brand name pumps rather than these modified/generic knock-offs?

I had a Bosch-brand 044 first and it didn't flow enough--it'd immediately overheat if you tried to BAP it. There's a reason that the Weldon was waiting to go in.

[scheides]

Ugh that is horrible news dude. That was the jay racing 044 right? Do they by chance make a submersible version?

No, they have the PT342 which is what I'm running in the in-tank. It supposedly flows 340lph like the Aeromotive. I put my ear up to it and it's humming away in the tank. I'll verify flow from it before I swap my Bosch in tonight but it sounds happy.

[mlomker]

As is often the case, the problem was not AT ALL what I thought it was. It turns out that the Jay Racing PT342 is actually a rebadged Aeromotive 340. What's interesting about the Aeromotive? Reverse polarity! It don't pump so good when wired backward. It does make sounds like it is working, however. lol.

I drove all the way to work on the 1/2gal that was in my surge tank.

Ah WTF!

Gonna be doing some wiring tonight then? lol

No real harm done since I didn't need a tow, so I'm laughing! lol.

I pulled the hanger and brought it home. I figure I'll go into work early tomorrow and drop the re-wired hanger back in the Evo. My boss was kind enough to give me a ride home to grab the beater.

Wouldn't most of the fuel from the surge tank just pass by the rail and go back into the primary tank via the return line? It seems like it would only take a minute for the external pump to go through the surge tank if the in tank pump wasn't doing anything to fill it.

Come to think of it, my 255 filled a gallon container in about a minute. Under throttle, most (if not all) of that is going to be used, but just cruising maybe 1/20th will be used, which means most of the gas just comes back through the return.

Is your surge tank 1/2 gallon? If so, it would only take about 30 seconds of your in-tank pump not flowing anything to run the surge tank dry, just because the external pump is always going to be flowing a lot, regardless if the motor uses it.

Or am I just high and not thinking clearly? Or maybe you have a return into the surge tank?

Correct, the engine return goes to the surge tank. Overflow from the surge tank returns to the main tank.

[asshanson]

Oh nice, didn't even think of that until after I wrote the post.
