I need a tank for my p100. I was hoping to find a tank with internal swirl so I don't need to run a lift pump, swirl etc. I've seen a couple of suppliers guarantee no surge but that's for injection use. Has anyone fitted anything simular? Was it sucsessful?

Edit: my p100 has a cossie lump. Should of mentioned that. Fail!

Thanks.

 

Tried a anti surge tank years ago for our xr2 zetec turbo. It was shit and still surged it tits off, since then we have all ways fitted swirl pots and twin pumps, as they work.

 

Interested in what you find out


I have spoke to pro alloy who have said they will sort something out for mine

I don't like the extra complexity of swirl pots and lift pumps
(But if that works then that's what I will have)

 

Just put a sump in the tank with a plate over it with small holes drilled in it so the fuel can drop into it but not slosh out under acceleration braking countering ect

 

Thanks for the info.

There is a guy on ebay bf fabfrications. Hes confidant that he can make a tank with ball bearing valves, sump, internal swirl and baffles that will be sufficient. Price is okay, might give it a try.

 

Yeah tank I have now has a huge sump and works fine

But changing position and size of tank

 

You dont make it clear what you are after.

Are you after a standard fit tank exactly same as the P100 ?

A modified version of above ?

Or a custom made tank to fit elsewhere ? What size ? capacity ?

A custom made to fit in same space/void as the original ? or shape is free ?

Engine is largely irrelevant, fuel injection is relevant, fuel flow required is relevant. If you are saying someone is making a tank for your application and will guarantee no surge...isnt that ok ?

Depending on space available, overall shape/size, making a custom tank that will not suffer from fuel surge is not difficult.

If you are wishing to retain an OEM tank and modify this for no surge, this can be more work.

 

I used allard to make mine.

 

Just save time and life and buy a ATL tank

 

Cha Ching

Do keep looking at these. With everything in its own box

 

All are Lots of dosh but they are the best

 

Sorry, let me rephrase.

My existing tank has been repaired and has a few rust issues. Plus as i have deleted the solid axle and installed IRS thus removing the tank brackets/mounts to make way for the beam mounts. So to sum up i really want to do away with the old and fit a new tank.

Now, where the original tank was mounted is preferably where i would like to home the new fuel cell. This is mainly because of the filler neck on the side of the tub plus i dont really want to be climbing into the back to fill up as i want to make a hard top for the tub.

Yes, i would like the tank to be made as it needs to be quite shallow. From what i read and the people i have spoken to the design of the tank is important by application ie N/A, Injection etc. 50ltr tank would be good so i can get to shows etc without fueling up every hour. In terms of measurement it needs to be around 600(w) x 200(h) x 400(d)mm.

Hope this helps

 

Oh, yeah, Gus. Where's it going?..

 

most n/a engines are fuel injected these days...I'd have thought a tank fabricator would be aware of this.

The shallow height is the only real awkward but here. That's the size of the main tank, would you have room for a small round sump say 4" tall and 4" diameter below the main body of the tank ? If so, that in conjunction with good internal baffling/collector should mean you will have a good solid supply under almost any circumstances

Failing that, and whilst it isnt as common, you could have a dual tank setup still within those dimensions.

ie build a swirl tank internally into the main tank, but it would still have a lift pump and main high pressure pump.

eg, Andy's setup in his Noble is pictured here, but you could build a cheaper version. And the small collector tank doesnt need to be round as per normal swirl tanks

On the rear bench where it should of gone first time round.

 

You going to sink it into the floor? (Excuse the crap old pics)

 

Thanks for the info Steve. I could have a large sump but it would need to be off set to avoid the prop. The prop is the main issue really.

May be another option would be to have a small external swirl? Would 8" tall be big enough? Does round or square make a difference?

 

No wont be sinking it as have a large back box underneath

Same sort of thing as your doing but all enclosed in own box

 

You need to calculate how big a swirl pot you need. There's guides online. Mines small, only 1l, but we worked out at full chat with my engine and injectors etc 1l would give me 30seconds of fuel before it emptied, IIRC, which is plenty.

 

Thanks that's interesting. Makes sense

 

The sump doesnt have to be centrally mounted. Yes ideally you would, but it wouldnt be essential if it gets you out of a hole.

Of course an external swirl/collector i an option...but it's more parts, more fittings etc etc If you're getting a custom tank made, then just have the "swirl" internally like Andy did with the Noble.

And no, a small collector tank does not have to be round. Again ideally yes, but certainly not essential, just the same as your main tank doesnt need to be round.

8" tall would be a fairly tall swirl tank, again it depends on diameter. 1.5 litre capacity is a fairly large swirl and depending on pumps and plumbing should be more than adequate for almost any car.
