Trunk mounted fuel cell install?

GSS138

Surge tank solution with duel pump or phunk's. I have seen the "racing", steel enclosed fuel cell in the trunk solution. It looks like a bomb and has high cg. Not explosionlessly or/and engineeringly sound imo. It just "seems" like a bad idea. Centered and low is the only real solution I think.

The surge tank solution I haven't priced, but it is not going to be less than phunk's solution.

U can look at other surge tanks like iridium but those go outside the tank and I do not want an external surge tank inside the cabin

synolimit

would the oem pump feed the surge tank and the motor would suck from that tank? so if the surge tank inside the oem tank runs dry the motor still feeds off the surge? or would that not work since the pumps sucked air theres no pressure behind the surge to force fuel into the motor? unless the surge has its own pump? i have tons of room where the muffler used to go under the car.

Iridium has another pump check them out there is also an article on moto iq

Surge tanks have their own pump. The fuel pressure in the stock system is regulated at the stock pump. Any external surge tank is going to require re-plumbing to a return fuel system. Really, just go to punk's in-tank solution. Another happy customer.

I investigated surge tank. Again very expensive option and adds complexity to your fueling system that can potentially fail.

The in tank system from phunk is the bomb for street/track car.

There are extra complications with the 370z (and 350z) that make installing an external surge can more complicated and expensive than other applications. Personally not being the biggest fan of secondary fuel storage outside the tank, these complications are what pushed me to build the RRP kit. I felt that in the end and for a similar price, most customers would prefer a fully in-tank fix.

The extra complications I refer to include, as mentioned before me, a requirement for return fuel conversion in order to regulate pressure after having taken the stock regulator out of the equation when using a pump outside the tank to provide rail pressure.

An extra complication that is not addressed in common installations of an external surge can to vehicles that were originally returnless, and something that most fuel system builders and product manufacturers have likely never considered, is that the 370z/350z in-tank Venturi siphon is going to cease to function. This can be resolved quite easily by someone who is familiar with the specifics of the (somewhat unique) z33-z34 fuel system, but again, adds more cost.

The 350z doesn't experience fuel starvation to the same severity as the 370z, but I am frequently asked about a fix. My RRP product is much too tall to fit the 350z tank, and I don't believe it would offer sufficient displacement after the dramatic size reduction. Also, the 350z fuel pump module doesn't offer external plumbing to interface, adding extra cost to convert it to a 370z style module such as perhaps borrowed from a G37 (shorter than the Z unit).

Because of this, I have had intentions to create a z33 specific external surge product. While my z34 product cannot be fit to a z33, my z33 product combined with my existing z34 return fuel systems options means that I will have everything in-house to put the external z33 unit into a z34.

I believe the combined hardware between the external surge product, return fuel conversion, and transfer siphon function repair, would meet or exceed my z34 RRP product cost. It will also have no concealability inside the fuel tank, adding the annoyances and risks associated with external secondary fuel storage. But one positive side effect is that after a portion of the expense brings a return fuel system conversion to the table, the end results include a fuel system that has been upgraded to support higher flow/power and also adjustable fuel pressure. All added plumbing being external offers a side benefit of ease to future upgrades to the system, and eliminates the customers/tuners general dependency on CJM to provide clear upgrade instructions as the (mostly misunderstood) RRP demands.

I can play my own devils advocate on the topic of external surge cans versus my RRP kit. If you want to do an external surge can, I can work with you a little on cost and I know how to do it without any 370z-debilitating side effects. I need to build this for the 350z anyway, so I am interested.

asking a questions isn't being difficult. i've seen the parts to use, just need a how to on wiring and such. there's 2-3 ways to do this. that's not difficulty if i choose to not pick the norm. i'm not a conformist. in fact everyone here is being a difficult kinda, not me. i've gotten nothing but peoples opinions on something i didn't ask about. take a look at my pic and if Rush is a "true story" then i'll keep doing what i've always done and might actually turn some heads doing it. in fact the more my questions are not answered and the more people create statments like this, the more i will actually never do what whats being said.

People are trying to be helpful and recommend against a potentially unwise course of action. Reacting in a rebellious manner to anyone that tries to steer you off the path you've chosen isn't necessarily a great default position to take in life. I get wanting to do you own thing; I'm frequently a victim of my own need to re-learn lessons the hard way long after the rest of society has moved past whatever it is and decided it's silly to even go down that road. It's not often a good impulse to have.

i 100% get that. i heard the first 15 times though. now i just want to move on. i just need a simple question or two answered is all. im not going down a rebellious path haha. i want something done on my car so ill go ahead and just do it. its not like it hasn't been done a million times before on other cars with 4 wheels that drive down the road. i dont see the rebellion in that. i havent done anything yet and im here talking about it first, getting ideas, asking about how to etc so that alone takes the "impulse" right out of it does it not?
