Fuel Tank

[p_b82]

Hi All,

Not sure if any-one is breaking anything atm, but if you are, I'd be interested in the fuel-tank given that mine leaks!

Diesel ideally, but as apparently they are interchangable I'll anything that's sound :)

I've no idea if it makes a difference but if yes, mine's a hatch....

Just seen this on f/b ZS Owners page

The tank & filler neck is the same the only difference is the collar that prevents wrong pump selection on the forecourt

I have either a second hand tank on my breaker (180) or....

A brand spanking new tank, never been fitted.

I was keeping the new fuel tank in case its ever needed on my car. However, I need to do a full Rotary Engine rebuild, so need every £ I can find at the moment!

So, I have no idea how much its worth, Rimmers doesn't have any price as NLA... Make me an offer if you are interested (in either one, just let me know which you want) and we can go from there :)

I'd rather the brand new one for piece of mind....

I don't want to take the ****, also I have no idea what the asking price would be - there's nothing on ebay for R45 or MG ZS, but going on other model's "buy it now" for a new one how does £125+ postage sound?
(I could potentially collect pending distances)

Feel free to PM to haggle further and/or sort out details :)

You need one for a diesel. They are different to the petrol ones inside. The diesel one has a crude swirl pot attached to the bottom which the petrol ones don't have. It's more of a baffle really but still different. I know because I tried to fit a diesel one to my race car... It didn't work as the petrol pump hit the baffle. Might work the other way round but why risk an air bubble in the diesel supply due to lack of the baffle?

[p_b82]

Thanks Phil - on looking more deeply, the ZS 180 and L series have a single hole tank - the smaller petrols a 2 hole.....

The haynes suggests that the difference with the two is indeed space for the fuel pump on the petrol - which we don't have on the diesel, as our fuel pump is on the front of the engine; in terms of it fitting, I shouldn't have a problem though.

As to needing a swirl-pot/baffle; should I find that I get issues, then a lift pump in the engine bay - pre fuel filter - would do the same thing (and is a thought anyway to help take a little load off the pump if I do go for big power with the custom injectors).

But......

I've got to cut my tank off - the nuts on the threaded bar are basically just rust (as I found out after disconnecting everything - should have checked them first!)...

So I need to get replacements on order before I get the dremmel out and a load of bricks for when the bolts are cut.

I've also learnt that diesel turns waxoil back into a liquid as I got covered in the stuff where I brushed against the under of the car where it had spilt.... and most of the back end of the car is pretty badly rusted as my eyes (then goggles) found out when it all fell in my face...

[peterzs]

petrol does the same as well.

[ZS Phil]

Even if you fit a lift pump along with a petrol fuel tank without the baffle you would still be more likely to get air in the system if you run it low and corner hard, lift pump won't stop it cavitating. Can get away with it a little in a petrol but if you get an air lock in the diesel pump its a full injector bleed.
If you keep it relatively full and you aren't pulling many g's on cornering I'm sure the petrol tank will be fine.

[p_b82]

Good points and I'm not saying that you don't have very valid points.... and for car that the owner just wants to take off and bolt on I agree 100% :)

But getting my hands on a good non-crusty diesel tank had proved to be a bit more of a challenge than a new petrol one :)

I've done a bit of digging, and there are a number of options for older cars that didn't have swirl-pots or baffles that have fuel starvation issues; and there are few potential solutions...

https://goo.gl/YsVXAg

an inbuilt electric low pressure pump and swirl pot designed for older diesel beemers - mount it on the bulkhead and then feed the output-inputs into the tank line -> OE fuel filter...

Or more crudely get a truck fuel filter - the capacity of those typically can handle enough to act as a swirl pot in their own right on a smaller capacity diesel like our L-series.

For the short term, as you say I'm sure this'll be fine as is, just when I start to track it I'll need to plan accordingly :)

[ZS Phil]

Look forward to seeing a properly sorted l series being tracked. I'm still beavering away with mine slowly but surely for a road orientated build but which will be just about hard-core enough for track.

I wonder if the engine warranty on my RX8 covers santa pod??? :)

But then I'd just have to rock up in the mustang - there is just no way my ZS would ever be as fast as that would be down the strip!

Hmm - potentially not; but then you could just say it was being driven enthusiastically! ;)

Hope you manage to get some-where with it and not end up paying the full price for the rebuild!

Hmm ... Think you're about 4.8 to 60 in the mustang - me too - would be an interesting quarter mile ... :)

Yeah around that - little quicker with the line-lock & launch control used.... but they invalidate the warranty so had better not.. It's 11 something to 100 iirc...
