Hey Phunk,

Any idea if this will work on a G37 fuel tank?

Hmm not too sure. Would have to get a few measurements from inside the gas tank if the tank is different. But perhaps its the same tank as in the 370Z. Would have to run a part number cross reference on that.

some of us with phunk's product have a ton of track experience and dedicated track only cars. No, maybe we don't compete, but we actually do drive our cars one or two weekends a month, and can run the tank completely dry if we want to.

There is some other consideration for the product that I have sold to you guys. The product itself is one thing, and the supplied installation kit and installation manual is another.

Set aside the installation kit and manual, which is based on integration with the stock fuel pump assembly... and you have a 1.9L or so displacement in-tank, self filling (via solid state jet pump and gravity check valve, not a bunch of extra electronic pumps) surge canister. It has 4x quick connect fittings for input and output. It holds up to 2 fuel pumps. The sky and imagination is the limit.

If you don't need the sacred FIA approved bladder that Shamus hard-parked Z needs, there is nothing going on inside his fuel cell, or anyone else's, that you cannot setup inside your tank. You want a bunch of Bosch scavenge pumps? Put them in and rock and roll! Return fuel conversion with adjustable regulator? I have it in stock.. And I was the first to do that for the 370z when Greddy asked me to

I simply gave a PnP installation method. So far, it appears to be holding up for you guys. But should anyone ever need to make changes, I designed the product to be endlessly versatile and there are no limits to what you can do with it so long as it fits inside a 19 gallon tank.

I don't understand all the hate for a product that solves the problem with fuel starvation. You can't just buy a fuel cell, throw a bunch of pumps in it, put it in the back of your car and call it certified because the fuel cell is certified. You need a full bulkhead, separating the driver from the cell, fuel lines have to be run correctly, etc... It can get expensive quickly and a lot of trackers don't need all of that extra stuff for what they're doing. CJM has been around the VQ community since the VQ35DE making great products, which I used. There are other options out there, surge tanks w/ large single or dual pumps can do the job for hi HP applications. Bottom line is your attitude smells like sh*t, your not that cool!

This thread is obviously about phunk's Fuel Starvation Control Product, so stay on topic. I've spent my time cleaning it, so I would appreciate not having to come back to clean more unrelated BS out of it.

:tup:

Mr Clean. It's spotless. :D

Thanks guys.

To continue on my last post.. It actually had me thinking.

Like I was saying, the installation kit and manual was centered around integration with the stock pump assembly so that you are 100% stock outside the tank. No need for return (unless wanted) no custom plumbing or AN lines needed, no external filter, compatible with stock fuel level gauge, etc

But if one of you decides to get crazier and wants to go return fuel and use our road race pump as a standalone pump and ditch the stock assembly, be sure and let me know cause I can whip up some nice small parts for that.

^ Your really something else. Just had to get the last word after this thread was cleaned up. No confusion. Start your own thread! And when it came to my words you DID clearly indicate I said something didn't. So welcome to my ignore list.

A little critisim is acceptable in my thread, i can deal with that.

im just happy to know that shamu doesnt still think that this is the answer:

http://www.the370z.com/1880797-post182.html

he may have overshot a little on the extreme end with little to no benefit (pending actual use of the vehicle when its done)... but at least he isnt running around the race track with a Folger's can in his tank anymore. he's come a long way, so ill give him that.

I guess it appeared as though I was asking instead of telling. Hopefully there is no mistaking now.

:iagree:

Did a trackday yesterday for the first time using "phunk's" kit. It worked great. When I was done for the day. I had one light showing on the fuel gauge. Never had any problems with fuel starvation the whole day. :tup: Used one tank of gas for 3 sessions. It took 17 gallons to refill it. Thanks phunk! :tiphat:

Awesome news.

incredible!!!

If there is enough interest, I am looking into building another batch of these now. Not sure if I should start a new thread for it perhaps? But I do need to gauge interest to give me an idea of how many to make, if any at all!

I am taking steps to investigate ways to try and reduce the cost a little bit. I am not sure if I will get far with that, or anywhere at all. Its pending some quotes I have going. But I would probably say its best idea to gauge it assuming the cost remained the same, and go from there. I know that if I can bring it down I will have a wider market. I intended to do some redesigning on it to make it easier to manufacture, but as time passes by, it just doesnt seem like something that is wise to invest my time into doing, for what I feel is a rather limited market.

From when I decide to pull the trigger on it and order material, we are probably looking at 8 weeks or so for production. Possibly sooner, but its hard to say having only made one batch so far.

If this product is something you would be interested in jumping on the next batch, please let me know. To date, I have not been contacted by any customers from the first batch to report any surprise issues.

370z Road Race Fuel Pump

I had a surprise issue! I didn't fill up my tank all day long at the track, and the car surprisingly didn't die :driving:

count me in

I erased all my PMs so i lost your price but if it is, what I think it was, I am in. :tup:

Will this fit g37 coupe?

On first post you said this unit is not for FI and FI people have to wait.. any update about that? (sorry i just cant read the whole 34 pages lol)

Count me in too

We have talked about that. For your basic FI kits on stock block under 550whp you will be OK. Or anything that may exceed 255lph. But any thing more than that Phunk will have to explain. There's a couple routes that can be taken.

At the same time I really wouldn't mind going with a return fuel system for this system.

To much to read. Why does this work? Is it like a surge tank? Is our fuel pumps just dangling in mid air inside the fuel tank?

And we talked about this and it is completely unnecessary under 600 rwhp.:hello:

Preparing for the future.

Lol then I will buy urs spohn! Hand me down parts!!

I still keep the surge can setup. It will just have a return fuel setup added to it. Along with two fuel pumps.

The stock pump effectively only pulls from one side of the tank with a big hump (over the drive-shaft) allowing all of the fuel to slosh sway from it. Phunk's product adds a second pump with its own second pickup on the other side of the tank. This second pump is in addition to the stock pump and lives inside a beautiful billet aluminum surge can. The new assembly is entirely contained within the stock fuel tank and the plumbing to the engine isn't changed. There is also some well engineered plumbing that goes on inside the tank to ensure long term reliability of the stock pump.

--A very happy customer.

I definitely have some interest. Wife and I intend to use the $20k+ that's now sunk into the Z. We both will be taking some lessons and getting some track time with it. I got fuel starvation on a right hander beating a light with 4-5 dots left. It took about 4-5 miles for the fuel gauge to read correctly again. I'm trying to squash any known issues this car has. Mine is SC'd and using Walboro255LPH already. I'm supposed to be around 500whp, but no numbers as GTM's still finishing things up.

Found out from a student I had that the Mustang Boss has a similar issue with 3/4 tank. That made me feel a little better about the Z.

Really! That's wild!

Nonetheless, seems like phunk has the solution for z's :)

The only cure for the problem is to buy a Z06 vette preferably blue.:hello:

Couldn't of said it better!. :tup: Happy with mine too! :tup:

In +1

Ahh thanks.

Wouldn't it be easier to just Tee a line in the tank so the pick up sucks from both sides at the same time? When turning right the one line goes dry but the others still submerged in fuel sucking it up? Or external sump that's always being filled and where the engine pulls from. I found the install, looks like a lot of work.

A simple tee wouldn't work - as soon as one starts sucking up vapors, the "seal" in the line is broken, and the pump will only try to suck from the vapor side. Path of least resistance, if you will.

I thought about that but there is a siphon on the drivers side of the tank. And since the fuel starve only happens on a right hand turn, that siphon never goes dry (which blows me away because from the pics it looks like left hand turns should fuel starve). if you tee'd into that siphon and ran a line to the passenger side and kept it low to the floor just like the hard line I'm talking about, I'd find it hard to believe the passenger side of the tank goes 100% dry with a line touching the floor. I don't know, I guess I have to pull it apart because I can't see why right hand turns are the issue, seems like lefts would be.

^i think if it was this simple, Phunk wouldve figured that out

Never hurts to ask and find out yourself. Companies make and sell stuff all the time and a back yard mechanic comes along and fixes something for $5 with duct tape, a Qtip, and a bag of marbles :tup: who else bought a OEM tank and cut it up?
