Hey,

Dose the in tank pump & pick up from a vitara have a built in surge?

Parry

[stockman]

No...

[Gwagensteve]

There's a swirl pot in the bottom of the tank. It's about the size of a milo tin.

So a built in pot the pump assembly slides into?

Do you know where I could find a picture? Thinking bout running the standard pump for the 16b in my crawler in a custom tank if possible as not much room to be mounting a surge tank

[jono165]

This is from some completely random Nissan but the setup is the same. There a small pot in the bottom of the tank that the fuel pickup sits in. The one in my coily tank thats in storage atm is about 150mm square and about 60mm high from memory.

[stockman]

The pick up sits inside the swirl pot, but it's no where near a surge tank and will eventually drain if the tank is empty enough and you're on a large enough angle for a prolonged time.
I'd be surprised if you need a surge tank.
Add a swirl pot, keeping more than 1/5th full and you should be fine.

[31zook]

Considering you will run on big angles allot of the time, I would suggest running a surge tank either way...

[Gwagensteve]

I have no idea what angle you'd need to be on to have a problem with fuel pickup with the stock swirl pot in the Vitara tank. We've been running vitara tanks for years and have never noticed fuel pick up as an issue.

I've had my car completely on its side, with the engine running, and messed around for some time until I was able to drive it back onto its wheels.

I think the key is to run a bit of fuel in the tank and it won't be a problem.

I don't think there's any place or need for an external surge tank in a 4WD. It's lots of junk that's not required in my opinion.

Steve.

I recently purchased a vitara going up a slight hill and starts spluttering any guesses what's the issue

[Davidmacca]

Off topic but while you are talking about fuel pumps, how do I wire my vitara Efi pump in after putting g16b in my swb

[Gwagensteve]

From memory the fuel pump wire is pink - it emerges from the fuel pump relay associated with the EFI wiring. run that to the tank. Pretty simple.

Steve.

[Rhinoman]

I've never heard of anyone with an EFI Vit having any fuelling issues related to the pump/pickup design.

[mnemonix]

In a Vitara that is probably correct, however I get the feeling Parry will be running that tank in a comp spec rock crawling buggy that will experience far more extreme conditions.

Keeping the tank full should a see the standard tanks swirl pot be sufficient. A surge tank gives a higher level of safety and reliability against lack of fuel.

[SierraDan]

Youll be sweet without a surge tank if you use a form of swirl pot and hoses as the lowest point.

[Gwagensteve]

Comp or not, with about 1/2 a tank of fuel, my engine will run happily with no wheels touching the ground, so I think that's probably good enough fuelling to avoid having to go the hassle of adding a surge tank.

I did have my car in an angle where the pickup ran dry the other day, but it was past 90˚and required recovery so I think its pretty irrelevant whether the engine was running or not in that situation.

In any case, if the stock vitara pickup isn't adequate, its still desirable to have the in tank swimmer pump feeding the surge tank, so there is no loss - it's not an either/or situation.

Steve.

PS, lets not forget there's a few reasons why "surge tanks" are like, fully hektik yo! - A) Because racecar! B) Because some very high horsepower cars can't be fuelled reliably by a single pump (see A) B) because lots of cars are EFI converted when they are turned into track/drag cars and therefore its easy to use a surge tank in the boot fed from the carby tank. C) and lastly because circuit cars can experience fuel starvation on long corners, again, often due to carby converted tanks being used.

I'm not saying surge tanks are pointless, far from it, but I think there is a bit of a "because racecar" attitude to them - if hektik 1000hp race cars use them, the my sierra with a G16B in it must need one too. I just don't think it's the case. They're vulnerable in an off road environment, noisy, bulky, and unreliable compared to the stock swimmer pump. which can reliably fuel any engine were likely to use as part of an EFI conversion.
