Orange petrol

[jakew009]

Will copper make petrol turn orange?

Pulled the fuel supply module apart this evening to replace the failing lift pump and noticed the fuel in it had turned orange.
It’s been sat in it for a few months and the only reason I can think for it would be the spigot of the pump is copper and the copper terminals.

Edit: I suppose it could also be the pvc cables

This has only been in there since October, I’m hoping the 200 plus litres in the tank isn’t like this or I’ll have a lifetimes supply for cleaning

Smell it you will know if it’s stale it might just be staining but that would worry me as something is breaking down

I've only ever seen that with petrol left a decade or more in a metal can.

I got some out of my motorbike same colour and that had been in the tank for 3 years

I don’t think it’s stale, smells fine, just don’t understand why it’s orange! Never seen anything like it before.

I’m sure the petrol in the main tank is fine, this was just in the fuel supply module on the back of the engine. Hold maybe a litre max.

That is pretty common in classics cars.

At some stage in its life, old fuel has been allowed to evaporate which leaves an orange coloured deposit.
When new fuel is added the deposits dissolve into the fuel, turning it orange. Unless the tank is cleaned, the orange tint can last for quite a long time. It has no detrimental effect on the fuel.

if the fuel that you are using has animal rendered bio constituents then the shelf life is less than six months.Adding fresh will help somewhat but not like it used to. I spend my evenings stripping carbs from outboards down to hedge strimmers,the last few years has seen a huge increase in evaporated fuel deposits.

Does petrol contain animal derived bio fuel? I thought it was plant derived ethanol that was the “bio” ingredient in petrol. I know diesel can contain animal fat (I bet the vegans don’t know that[emoji6]) but I didn’t know petrol did.

Is any biodiesel on the market today actually made from animal fat?

I think our Irish correspondent is telling porkies

I wonder who will open the first vegan diesel pump

[beerbelly]

i dont think its deposits from the tank or colouring from copper .i went to check on my rib at the boat yard yesterday and the fuel in the clear water bowl on the filter had an orange look about it .its been stood under cover since october .i fired it up on muffs and within a few mins the fuel in the bowl was back to the almost clear fuel colour . its a 1 year old stainless tank and a 1 year old racor filter unit so i doubt any deposits are present .i put a couple of bottles of fuel stabaliser in the tank when i laid it up but dont know if any of the treated fuel would have got into the filter .a guy i was talking too at the yard reckoned its just the ethanol in the fuel that causes it and it will be worse when we go onto e10

Pork I am not sure about ,but rendered animal fats \Tallow and their distilled derivatives are added to ,not made from to petrol in order to comply with the EU directives on Bio fuel..I have that Information from someone who works in a refinry. and for some more useless information the next time you sip some of the worlds so called best whiskeys ,it too may be fermented from rendered animal fat and not the grains printed on the label. The RAC website actually give the shelflife of petrol as low as three months in certain cases but maybe they are telling PORKIES as well.
