No pics, but in my daily-drive Sierra I have a Speco brand glass with wire mesh inline filter mounted half way along the carby fuel hose. It is cabletied to the PCV breather hose.

It just had shit in it... And a lot of components didn't work, so I got a reconditioned one and that 100 percent fixed the problem! Very happy customer :D

But didn't they put on a recon carbie on and it still played up a few days later? Shit in your fuel lines?

it's just a low pressure plastic fuel filter with straight barbs on it, any auto shop will be able to help

Awesome - thanks. This may be a stupid question but will it affect the fuel getting into the carby? When starting and stuff

Those exact filters you can get at SuperCrap for $3. Their good because you can tell what shits in them and if there's any water in your juice

Post subject:  Re: 2nd fuel filter in engine bay

I would run one of these before your factory filter as the filtration won't be fine enough. Put it somewhere that you can get at and out of the way. Alot of diesels run a CAV filter with a water seperator which work well, not sure if they are only for diesels?

I think the point of having it in the engine bay is to stop crap from the fuel pump membrane getting through or something?

I also replaced the stock filter with an inline efi filter,
got it for $30 brand new, think was from a commodore?
They filter better, and last a very long time

Personally I wouldn't keep a large volume filter above the engine - I'd be worried about boiling the fuel but then again i'm not a mechanic.

I have this one and it's a fraction of the volume and re-usable as well.

If you are worried about price, repco sell these Ryco Z676 'tiny' ones for less than $10 and they don't occupy much more space than the hose itself and you could put one on the carby end of the hose and not have to tie it down...

I'd use the Ryco ones next-time and just replace it every so often.

Would these filters, with a water seperator, be any benefit in a petrol engine? I know they are very common mods for diesels but haven't heard of them being used in petrols?

I have been doing abit of research around this filtration for petrols and have found that a Lucas/Delphi HDF296 CAV filter will work on petrol. They have a filtration rating of 6microns and a flow rate of 45L/hr. You can buy a pack of 10 from ebay for about $25 Armsup

There are a few people running them on carbi, efi seems abit more complicated. I will have abit more of a read before I suggest anyone with an efi to run them....

No point having a water seperator filter in a petrol vehicle... Just add a litre of metho to the tank every few months..
Metho is hygroscopic so it absorbs the water. Metho mixes with petrol and gets burnt.

Metho doesn't mix with diesel so you can't use it and need a proper water seperator filter.

What are the issues with EFI? Is it the fuel pressure or flow rate???

Author:  Scales [ Sun Aug 12, 2012 11:03 am ]
Post subject:  Re: 2nd fuel filter in engine bay

EFI requires a high pressure filter. usually a metal one, for christ sakes if you have EFI, DO NOT put a $3 placcy one from supercheap in.

it WILL rupture, and you will have a lovely engine fire to deal with!!!!!

remember EFI fuel pressures are around 60psi, so even the hoses you need to be carefull with!

Last "Metho" i bought was named 100% ethanol on the back

Not sure if they still make the old style

Post subject:  Re: 2nd fuel filter in engine bay

Yes it is the fuel pressure that does it apparantly. 60psi is efi however most supply pressure for common rail is above 100psi and the new lift king that arrived at work is common rail and has a cav type filter.

Want33s I would be getting a cav type filter for the filter price and ease of replacement.

Flow rate should be fine EFI
