I know some cars are more prone to fuel starvation than others. I haven't heard of or seen many hondas running a surge tank, I wonder how much they benefit.
@@dropinbiking92 If they're not starving unless the tank is quite empty then there wouldn't really be a benefit I guess. Some cars will suffer from fuel starvation even on a 1/2 tank so it would be more beneficial in those cases.
Old video, but you should have reversed the two connections closer to the main outlet to maximise the amount of HOT fuel that goes back to the tank for time to cool and minimise the temperature in the surge tank. You could have ordered the 3 worse, but also better. Fuel being not-water expands quite a lot when it heats and unless you have measurement of that and compensation in your ECU (factory don't have it) that hot fuel both leans out your open-loop tune slightly and increases the hot-start issues causes by boiling in the injectors and rail.
That's actually especially true because you have your pump inside the tank being cooled by the surrounding fuel. So flushing that fuel out back to the tank as much as possible is for sure on your agenda. I wouldn't ever run the pump in there like that. It gets enough cooling from radiant, air convection, and fuel passing through at a high rate and leaves more volume of fuel in the surge tank, and ability to put structures in place to give you quality fueling right up until the surge tank runs dry, along with a properly smooth inlet path to the pump from the tank. None of that is possible with the tank inside like that, really.
Question: Isn't having exposed electrical connections inside the surge tank a bad idea? Fuel will be splashing around inside the tank and will cross connections causing shorts. There's also the possibility of creating sparks in a tank full of explosive liquid.
Gasoline is non conductive and even E85 with it's higher conductivity is still not conductive enough for it to be an issue. You also need to have the right mixture (gasoline vapour and air) for it to be flammable/combustible, same principle as in the engine. Because the flammability limits of gasoline vapours are very limited, the mixture in the tank is well above the point were it's flammable even if an ignition source is present aka the spark- around 1.4% to 7.6% by volume of air.
Your fuel pump doesn't vary in its delivery. If the car is on, it's pumping fuel 100% of the time at full force. It does that to keep fuel pressure. Your fuel injectors (or carburetor if your car is quite old) handle the ups and downs of fuel delivery depending on you pressing the gas pedal. If you're not using all of that fuel the pump is delivering, it will send it back into the tank to be recycled until it is needed. In my car there is no return line all the way back from the engine, the pump reaches its desired pressure and anything more than that is dumped from the pump via a bypass valve without leaving the tank.
Great video, Sam! Absolutely love the "How To" videos! Keep up the awesome work!
love watching you work on these bad ass rides! I have been watching your videos from the start, and trying to catch up to your current videos.
First.
Thanks for the GREAT content! Keep it up sammit!
Nuke is premium stuff, swedes really know how to do it.
Cheers man, I got a xr8 turbo I'm setting up a surge tank in, this helped out. From your brother country NZ
always make sure to roll a big fat king kong finger blunt before watching
I tried putting it in my boot but my foot kept getting wet.
Wheres the side marker light? I thought you got the wire harness you needed.
And now you can say then your tank lights comes on : it's fine i can drive 100km :D
Nuke performance do BMW parts . I have euro S50 fuel rail
mr323i I have a BMW too it's an e46 compact and its sliver Ye Ye bra 😀😀😀👍🏻😜
Like the how to videos keep them coming.
We want Mae!!! We want Mae!!! We want Mae!!! We want Mae!!! We want Mae!!! We want Mae!!!
It's OK to have exposed wiring in a gas environment like that?
They should put a little window in like a kettle so you can see the fuel
Notif squadddd
Are surge tanks a common thing with the grip cars, like the hardcore civcs and stuff?
Anything that sees high G's (especially lateral) should run a surge tank, so it is common to see them on grip cars.

pushed liked for hes smile, lets se if the rest is good.

Double bucket wash only.
"That's not going anywhere." lol
13:00 Sock... fuel sock.
You wash your car but have a look at that boot lip...
I didnt even knew that there is fuel comming back from the engine, but I still didnt quite get why there is fuel returning.

my engine boggs down on high G, I have a C35 laurel it probably has a similar tank to the r34..
