Can you use a CAV filter on petrol motors

[Surfin Alec]

I have a CAV type filter that I took off my diesel cruiser. The cartridge filter with glass bowl type. I was gonna give it to the old mans for his petrol 3f troopty. The filter says diesel filter on it.

I am sure you could but is there anything I dont know about why it shouldnt be used on a petrol motor?

They are used on petrol powered boats but not recommended for premix 2 stroke outboards as possibly can separate the oil out. Main purpose on petrol powered boats is water separation, not filtration efficiency.

Using it on a petrol 4WD is probably overkill. May also be an issue with pressure drop and you might find the fuel pump cant supply enough at max load.

I have heard sumwhere years ago that there is 2 cartridges available for them...petrol and diesel.
Anyone know if this is right...or anything about it???

on my old suzuki i used to use a proper diesel filter as in one of the large ones the size of a oil filter.. worked great. but yeah that would be overkill!

Ran 1 yaers ago on a 327 Monaro because I had it. Seemed to work ok and had no probs that I can recall.

I was under the assumption that if you have a fuel pump in the tank it would blow the bottom glass of the filter as it is meant for suction (pump after filter).

Not too sure where the pump for your dads would be.

Seen them used on petrol forklifts, on both suction (pefor pump) and pressure (after pump) sides with no problems.
Should work well. They trap the water well, proberbly a lot finer filter than standard, and elements are cheap.

The old mans petrol troopy (carby model)has the pump on the motor (mechanical type). I am sure there wouldn't be an electric pump in the tank.

I know it might be Overkill but I was just gonna lob it and he seemed keen on it as he hasnt changed his in line in god only knows how long.

Another reason is that he runs LPG 99% of the time and it may seperate any condensation build up as it takes him weeks to use the tank of petrol up.

you would need about 100psi of pressure to break the glass!!!

Ive put 150psi into one to try and bust it, nothing happened, 180psi and my airline came off the spud fitting.

the repco copy (in the latest supercheap pamflet) I believe the glass bowl is held on by nothing more than a push on rubber seal. So in this case it could blow the glass off (not blow the glass to pieces though).

I believe the cav filters are a screw on type arrangement though

[Surfin Alec]

The CAV in question has a bolt on top that goes through the filter cartridge and into the bottom plate that holds the glass on and the filter all together. All very sturdy. Glass is about 4 - 5mm thick.

have one on my petrol scout, using an electric holley fuel pump works no worries , put it on cause i use alot of drum fuel which some times has water in it so the glass bowl comes in handy ,has a drain on the bottom to let any water out.
