Hey Zookers...

So about to finally transplant the 16B into the Project.

The tank with fuel pump from the doner vitara is really crusty inside and our original tank is protein inside so we've decided to stick with the original tank and just use an inline fuel pump. The bucket loads of universal pumps on EvilBay and I also notice many peeps use the faithful VL Commondore pump.

Any recommendations? Also what flowrate/pressure should i be using for the G16B?

K&N have a nice pump kit for under $100 delivered theres 3 options ranging from 15gph/3psi - 32gph/10psi

Thanks
Bretski

Well a g16b needs 40psi so the crap&n kits aren't going to cut it.

I would do ANYTHING to avoid an external pump.

Why do you say that? External pump easy access and easy to service... Im genuinely curious and could easily be swayed...

I have both tanks... Just the fuel pump tank is rusty and crusty as hell on the inside... Will need an acid bath and new coating... and either way i have to buy a new pump.

Because of basic engieering. A swimmer pump is more reliable, with less hose and electrical connections. It's also less vulnerable to off-road damage, runs cooler and consumes less power.

An in line pump requires a surge tank and lift pump. Messy and complex to package. last one I played with had 14 more hose connections than a swimmer pump.

There's a reason the factory use swimmer pumps.

Thanks mate...
Will take into consideration.

I run the VL pump without a lift pump or surge tank, but the pump sits lower then the tank so is gravity fed without any dramas.

Thanks for the feedback

This is simply not true. Although I also prefer swimmers, you do not need a surge tank or lift pump. The efficiency of the pump will be a lot lower without a lift pump, but the VL pump is more than up to the task.

P.s. camira pumps are the same as VL turbo, VN v8 etc and are external from factory. If you want to head to Upull it for a cheap unit

Just mount with gravity on your side like the above post.

So a vl pump lifting fuel out of a sierra tank, which doesn't have a swirl pot or any baffles?

Sounds like a tops setup.

I think JrZook runs that setup? Don't quote me on it, but I remember reading that all he has is an external VL pump and despite not claiming it as the best option has caused him no issues unless the fuel level gets stupidly low?

Regardless, I'd take a OEM swimmer pump all day given the chance.

I had the vl pump only set up , was assured it was fine and did run fine for 3 months befor dieing in the middle of no where at 1am.
I now run surge tank and lift pump , has been trouble free for 3 years , but would love a swimmer pump to get rid if the mess of hoses under the car. Looks like a problem waiting to happen.

So after all the comments I've decided to try and get the EFI tank cleaned up. Its going for an Acid bath tomorrow to clean out all the scale and rust inside and i'll give it a good lick of paint. Ive ordered a new pump and should be all sweet.

It was surprising that the stock tanks don't have a drain hole/bung. I had to cut a hole in the bottom to drain all the scungy stinky old fuel and slugde out. One cleaned up i'll braise a new drain threaded seat into the hole

[Gwagensteve]

Right choice. You won't regret it.

If i can't clean up the EFI tank going to cut the pump mounting ring outta the crappy tank and put into the good tank.

Good choice. A swimmer is a better choice if you have the opportunity to run it

Yea just running a fuelmiser VL pump mounted on the chassis (re: higher than the fuel level in the tank). The first pump I had (beatup secondhandy with unknown hours) lasted around 35 thou and was run till empty quite a few times. The brand new fuelmiser pump has around 30tho on it already and is going strong. Only starts to cavitate on corners when the fuel level approaches 1/8th of a tank (roughly 33L consumed, straight tank). On flat road it will work upto 36-38L. Apart from that its very quiet.

After a bit of hunting I wen to a few places this morning to see about getting the tank cleaned and re-plated. Turns out that this will be VERY expensive... Bummer...

Then on the way back I drove past a radiator repair place and thought "worth a shot" dude was very helpful. Turns out they do tank cleaning and repairs and use a product called Redcote to coat the inside of the tank and will last the life of the tank ... Will keep you guys posted on how it turns out

umm - should be fine - I once had a 'cracked' tank - local radiator guy, fitted a drain bung and coated it internally with some sort of reddish pinkish stuff, had no further issues with it when he was done.

Sounds like whats getting done to mine... No cracks tho... tank in good nick other than full of slime and scale ...fingers crossed...

I run a self priming (to 0.5m) pierberg mercedes inline pump.
There a bit more expensive but are dead silent and the ones ive had in 2 zooks with over 170xxx kms combined have been flawless.
They are one of the only self priming pumps out there that dont need a facet type lift pump/surge tank setup.

Agree with Mercedes Benz pumps - most of the 1980s - 90s Benzs (W114 / W123 / W126) cars ran a gravity feed in-line barrel pump, with a filter & 'surge' tank all bolted on the same mounting bracket assembly - neat, (metal pipes, using banjo bolts between these bits) contained, easily accessible, long lasting, but is designed to be gravity feed.
Most Suzuki's are not going to be too bad in accessing the original tank area, to remove a swimmer pump, some cars though can end up an absolute mission to drop the tank (Range Rover Classic 3.9 V8EFI - aftermarket R/H 1/4 panel tank, due to scuba LPG tanks where the original petrol tank is, modified towbar with rear wheel carrier attachments & 'wrap around' 1/4 panel protection bar - running the original swimmer pump. It it ever fails when out on a trip, I'd better have some strong & patient mates along!.
Just saying, some cars might be better off running a in-line pump & there are plenty of 'factory' examples where this is done.
