Fuel filters and locations?

[Cool1]

Would an OEM filter from a falcoon or similar be too much of a restriction before the lift pump?

[takai]

Falcon filters would be high pressure wouldnt it? If so i wouldnt use it, they tend to be nasty at low pressure.

[Joorsh]

I'm using the standard Toyota 2J filter on mine. Just threw it on in-line just before the fuel rail.

[Cool1]

Yeah i'm pretty sure the falcon filter would normally be fitted after the pump.

Not many Pre-EA Foulcans were efi. most of these though used placcy filters. There was either a commonwhore or foulcan efi filter that was female thread both ends, and the hefty price of about 12 bux for a ryco item, dont remember part number, or car it came off, but head down to autobarn, and sift through their range of efi filters. While your at it, quiz them if there is a low pressure metal can filter about. I think they may even stock strainer filters n all.

Depends what sort of filter you run. I have a 100 micron strainer type filter before my high pressure pump. It cost me $15 from Speed Technology. Whilst a filter before the surge tank should theoretically suffice, unfortunately scale/other gunk can develop in the surge tank itself, loosen and eventually find its way into the high pressure pump destroying it.

I run 3 filters - a conventional 12 micron filter pre low pressure pump, a 100 micron strainer before the high pressure pump and a conventional 4 micron EFI filter after the EFI pump.

EA Falcon and some V8 Commodore filters are great for conversions - push on fittings, linear and roughly the same OD as ignition coils, so you can use an old ignition coil bracket to mount them securely.

As above is indeed the "Correct" installation. Before your lift pump any low pressure carby filter will work fine. I use a plastic Ryco Z14 as it has 5/16 barb fittings to suit my line size. Before the main pump needs to be a prefilter, ie a Gauze strainer basically. GT's sound like the goods, mine cost a little more (Was $22 from memory) and is a 1/2" in/out plastic unit, perfect size for my VL turbo fuel pump . They work great but are hard to find so I order them into work here by the dozen. My EFI filter is a steel Ryco Z200, again because its cheap, common, and has 5/16 Barbed fittings.

That raises another point. Is it just me or is the inlet and outlet of the Walbro pumps rather small?

[Cool1]

I've added some prices for the earls filters in the first post.

[TheToyman75]

Just a quick comment on the earls style filters. Take a good look at the actual size (Surface area) of the filter element. Its damn small and they are prone to blocking quickly thus reducing fuel flow and potentially cause an engine to fuel starve and lean out.

A transparent prefilter with a much larger surface area on the filter element was a much more comfortabe (and cheaper) option for me.

The filter between the surge tank and the high pressure pump will have to be mounted in the boot of my car. I was thinking about using one of those clear filters, but everyone car I have seen with one mounted in the boot seemed to smell like it had a fuel leak
I would also have o find one that can flow enough to not hurt the high pressure pump.

[chris davey]

what filters are people using that have aftermarket intank efi pump like walbro? No surge tank install.

[roadsailing]

your walbro will have a strainer filter on the intake, put a high-pressure filter after it, i put mine in the engine bay for ease of service.

[chris davey]

thought so, just checking

Most "strainer" sized filters i've seen are plastic.

You might have more luck enquiring at bike stores/service centres.

[takai]

Yeah, i have a stock AE92 SX fuel filter in mine, With a couple of spiffy adaptors so it doesnt have to use banjo lines. The big advantage with these is that they come attached to a nice little bracket, perfect for mounting in boots or similar.
