In-line oil filter By 13lky2 (Read 1,835 times)

Has anyone tried installing an in-line oil filter? I figured with running an external oil cooler, I could just add a screw on filter to give filtering beyond the capabilities of the metal screen. I did this back in the day on my VWs. My only concern is if it would impede the external pump or if I should look for one with a slightly higher flow rate. If I remember right, JR was using a 20 GPH pump.

We had a few guys look into this and the problem was finding an inline filter that could handle hot oil. Everything on the searches brought up injection oil filters and of course that's not hot. I think the screw on adapters would be your best bet. Rich

I was looking as something like this.

The trouble is that it's so big. Hard to find a place on a scoot to mount it.

That's the same size to what I used on the VW, I guess I figured someone made a smaller setup. Hmmm, now if I only had metal fab tools..... I could be rich!!! ;D

There are some smaller ones designed for small Honda engines but the price will make you shudder. Like $150+.

I've been meaning to get back to you all on this inline oil filter because we went into this quite a bit about six months ago. We covered everything from these el-cheapos:

^Visu-filter

To these that are over a hundred bucks:

I just put a post over in tech archives about a guy that used this spin on adapter:

Here's a link to that post and there's a link to a vendor within it. Rich

gotta love the el-cheapos... they actually work very well...

Really! Cool! The argument against them was that they may not stand up to the heat. But my thought was that the oil circulating through them is not THAT hot. I've discovered that most auto/marine applications are over engineered because of the harsh environment they'll be exposed to. So I figured that even if the Visu was designed for injection it probably would still hold up well enough. But I was too buk buk to try it. I didn't want hot oil shooting all over in the middle of a ride. Another instance would be Dr. JR and Wildman using fuel pumps as oil pumps. In the same vein I wondered if plastic vac fittings would hold up as fuel line connectors in a pinch. The guy at the local auto parts store assured me they would. So I put a "Y" vac connector in a jar of gasoline and ended up forgetting about it. I was looking for something in the shop about six weeks later and ran across the experiment. I thought the fitting would be melted but it looked like new so I wouldn't hesitate to use them in a gas line. That Visu is high flow/low resistance too; I think it woul be OK with the low pressure GY6 oil pumps we have. Rich

Yeah, the plastic on those filters is fairly sophisticated PET or something and it will easily take 350deg which is way above the temperature of the oil. Most times I have seen these is on the flow back side of the oil cooler, so the temperature is probably 150deg at most...

Do you thing they would work as Fuel Filters or are they to porous for that and not trap micro stuff that could clog the jets and or passages?

Maybe I'll give the el cheapos a try in my oil cooling system, although I was seriously looking at the spin on mod.

I use an idential filter for fuel from Briggs and Stratton . $5.00

It works really well on a gravity feed and has a 170 micron filter that is about double what the auto fuel filters are...

I have seen them from some suppliers in clear as well

The red colour is a safety thing to indicate it is a fuel line...

I just replace them every year...
