Robert,

Did you make sure that it doesn't interfere with the fuel level reader? Also when at the gas pump it may say your full, but can actually take more gas if you wait for it to settle in the tank. Not sure...just some thoughts.

Anthony:

Funny you mention the fuel level reader. One of my pieces of foam moved and interfered with my drivers side level indicator, which messed up the law of averages and left me on the side of the highway last night at 3 am. WTG.

On a positive note - I fixed it in about 12 minutes today and got a bit of a workout in last night while walking.

The foam does not seem to have any effect on filling. I've put two tanks in without issue.

I will continue to have to experiment with this. and find the right angles and placement. I'm 75% sure I'll be opening up this gas tank 133 more times. I do agree with Phunk, that it will probably not solve the issue for the last remaining bit of fuel, BUT it is working. The current setup I have will NOT allow fuel to flow to one side of the tank or the other at a rapid rate, so slalom or chicane style turns will become safer. I have yet to test it out on a 95 mph sweeper - and probably wont until I can get somewhere SAFE and way off the beaten path of traffic. I do have a track event come May, so if I don't test the sweeper by then, I'll test it in May. I plan on making foam and tool with me to the track to preform more testing.

I did create a mockup of our tank and installed some foam just to watch how it worked. Pretty cool stuff. One side of the tank can be completely turbulent and the other is hardly wavy. This is positive improvement. I think if your sweeping turn is less than 3 seconds long, the foam may work out well.

To be continued...

I don't know if Z's can suffer from overfilling the gas tank. On other vehicles I used to fill it to the very top until I could see gas almost coming out of the fill port. Well, little I knew that I was damaging the charcoal canister AKA evap canister. Once I learned my lesson (a few hundred dollars) once the fuel nozzle stops pumping gas, I stop pumping gas as well.
What I was doing is overfilling the tank and any excess was being poured into the charcoal canister thus saturating it. Once the canister becomes saturated is useless and can cost as much as $800 for some vehicles.

Robert,

Great update and sorry to hear you got stranded! Curious to where you are actually placing the foam in the tank. I would think that just putting on the middle hump would keep the fuel from sloshing to the other side at a rapid rate. Not sure how you would keep the foam in that one location though as your driving.

You would really have to sandwich it in there tight to keep it from moving, but that would have to added benefit of making the foam very dense and help with the anti-slosh effect....but maybe too dense?

Mr. nismo,

I was more concerned with under filling the tank with the foam in there.

Finally got the engine starting!
Man what a relief!
I still have a few things to do, but now I can see the end closing!

'bout f!@kinf time. :icon17: Been worring about you.

I was worried too lol

Thanks a lot for your help rusty.

Ready to pull the trigger on this when the next round comes out. Hopefully soon. NA, so dont need additional flow capability or the associated added cost. Easier install would be a big plus

Same deal, put it t market and Im in. I ruined an entire session last weekend by forgetting to top off. I hope to prevent that from ever happening again.

Ugh, i did that last track event. It's like burning a $50 bill up. So aggravating.

You guys got to get on phunk's butt about RRP V2. :D

I talked to Mr. Charles on Wednesday actually!!! He needs to get V.2 out the door!!

BTDT. Installed Phunk's set up and my wife ran the Z down to under 1/4 tank at an event in March without telling me.......no issues whatsoever. Plus it's nice to lose the weight of all that extra fuel each session. :tup:

One word...Retrofit!
