CAV Fuel Filter

[cowdotpat]

Can anyone tell me about the CAV or similar converions available for my 2 filter 78 series troopie? I hear they can be a great sucess allowing the use of much cheaper spin-on filters but I am also vaguely aware there my be some drawbacks, increased restricton in fuel supply / fuel starvation? I thought I also read a recommendation to add an electric fuel pump?

If it is a good upgrade then who supplies them (I'm in West Australia)

I'd be grateful to anyone with some experience to set me on the right path.

The filters are cheaper but the original type can be bought at Malz cheap enough,I think they are $19 for a Ryco compared to the CAV type at $8. Its going to cost $200 approx to replace what you have.

I considered it but it would take a lot of filter changes to get my money back.


I dont believe electric fuel pumps are needed . The FSM says you need 2psi in the fuel lines and 7 psi internal pressure inside the fuel pump(adjustable I think).
Besides that ,the injector pump is already capable of pumping 54 litres an hour at 2000rpm.
At those engine speeds you can only use about a 3rd of that under very heavy going.

I have a combined filer /water separator CAV type on my other landcruiser and no problems with fuel restriction.

Any diesel shop will sell them as well as Coventrys and ebay.
You can also get an adapter that fits onto your existing filter head and allows you to use the cheaper filters.
These cost about $120 and would still take a lot of filter changes to make it worthwhile.

If you decide to change them,make sure it will fit,there is limited room from the inside fender and the master cyls

Rosco, Thanks for taking the time to put together your very helpful post. You've ease my mind. I have replaced both filters once and bought replacements ready for the next time. (I'm running good quality bio diesel which is cleaning out the system and I anticipate a few filter changes) I remember one of the filters was not expensive but one is available from toyota only (?) and was $30 to $40 from memory. It wasn't hard to change but it wasn't as easy as a spin on either. I'll check out Malz

Thanks again

I got both the fuel filter(larger one) and the smaller pre filter ,both Ryco,from Malz.

Easiest way to put any of those filters on is to remove the whole filter head and do it on a bench.

The factory filter are prone to air leakage if your not careful putting them on.

I wasnt aware your using bio diesel which is a little more viscous. If your worried about fuel starvation maybe see a diesel shop and get them to test the fuel pressure as outlined in the FSM

Will definately take your advise re bench change and will check out Malz. I didn't know of them but they are pretty convenient for me as it turns out.

Much appreciated
