Thanks. Yeah, I was lucky this weekend. I didn't expect it to happen so when it did I questioned what was going on. Ran it WAY too many laps with the issue. I won't be putting it on the track again without an A/F. Better call Galeforce and see if he has any A pillars in stock.

So what is the real fix for this? I'm so tired of sputtering coming out of right handers! It seems like a fuel sump would be a logical fix.. I'm even getting this with over half a tank of fuel!

I get it before I'm at 3/4 tank, Punks kit is the only option I've seen.

I'm sure it works, but I am hoping for a little cleaner bolt on solution. I'm not crazy about putting all that stuff in the tank..

JWillis72 · 09-10-2014, 10:50 AM

If you find something else that works please let us know!

Anyone know around how many hours labor a dealer would charge to change out the fuel pump?
I want to hit the track after winter, so this might be a smart.

JWillis72 · 09-10-2014, 11:40 AM

I was told 6-10 hours in the other thread.

Arrvaxx · 09-10-2014, 12:09 PM

I think this would be a good time to find a performance shop and have them do it. 6-10 hours at a dealer would break my bank.

LOL to each their own I suppose... the entire purpose of putting it all in the tank is to make it cleaner. I am not a fan of external fuel storage containers, pumps, and fuel lines looping all about the car! The RRP is 100% concealed inside the fuel tank... you wont find anything cleaner!

The Nissan dealer is not qualified to install this type of product! No way! Skilled performance shops only.

Not because the job is hard, but because a very high percentage of people who get jobs working on cars, have no business working on cars!

Arrvaxx · 09-10-2014, 06:34 PM

Phunk what is the estimated pro install time required for your pump? It certainly looks like the solution.

phunk · 09-10-2014, 07:02 PM

6-10 hours is the official estimate.

If you could just turn the gas tank inside-out... this would literally be like a 2 hour job at most. All of the difficulty stems from having limited space to reach inside the tank to work, and very limited line-of-sight.

When people have made small goof-ups during install, it generally takes them HOURS of work to figure out where they went wrong (then again, I believe a large percentage of this time is in the hesitation to go back inside the tank and actually look, versus theoretical diagnostics). This poor line-of-sight seems to prevent them from being able to take it all in at once and see how its supposed to work. I get the impression that everyone feels like they are working blind (literally and figuratively). If all goes well, than it doesn't matter and they are on their merry way. If something isn't correct, it becomes difficult to diagnose if you don't have the big picture of its functionality.

There are ABOUT 40 RRPs out there installed now. I would say 3-4 guys had a couple issues, and 1-2 of them had it painfully set them back with frustration for a couple days worth of spare time.

Now I must add here... your application of higher HP is going to require some added hassle unfortunately. The RRP kit is based on a single Walbro 255 pump in its standard configuration. The RRP was designed with higher output in mind and has upgrade-ability built into it... but nobody has yet put it through its paces on a car as powerful as yours. I would have put together a customized kit for you and communicate directly with your installer about how to set it up and what to watch for to make sure everything is OK.

Arrvaxx · 09-10-2014, 07:21 PM

Yeah I have already talked to Tony at Fast Intentions. He wants to be involved too in case they need to modify anything. I will reach out in a bit.

Rusty · 09-10-2014, 07:49 PM

After installing mine. I think I could install one now in under 6 hrs. The main thing is taking the seats out, with the rear interior panels to get working room.

Super Werty · 09-10-2014, 07:56 PM

how is it that DJTodd was able to run this track with all his power and E85 without running into this starvation issue?

is this strictly related to auto x events with super tight turns?
