Secondary Fuel Filter

Looking at the workshop manual, it says that the 1HZ has a secondary fuel filter. Mine doesnt. I have an 93 75 series. Is it needed or not? If it is, is there much to installing one?

The fuel filter situation seems a bit vauge to me. My '95 hzj75 troopy has two filters, when I bought it at 30,000km ( all sevices performed by toyota dealers) the fuel was plumbed to the plain paper filter first then to the normal filter with water trap. This seemed completely stupid to me so I changed the hoses around so that the water trap filter is first in the system. I have done another 350,000km since and never seen any need for both filters. If you are using suspect fuel maybe, but service station fuel is usually pretty clean.
Any other opinions?

I think thats what the previous owner has done. the mounting brackets are there but the filter has been removed for the secondary filter.

I'd put it on the one day list. If you happen to find a filter assembly dirt cheap stick it in if you like, but as I said, I don't think the secondary is at all necessary. Ed
