Oil Bypass, cheap

E-mailed them last night, haven't got a response. From what I've seen in the field, the EA filters have built in flow restrictors. That's why they are sold as a "by-pass" filter and not a full flow filter. Edit: (We use the EABP120 to bypass filter our hydraulic drive units at work)

I totally understand what you are saying but before it goes on my truck I need to know 100%. If the filter won't regulate 1/2-3/4 of a quart per min it ain't going on my truck!! It would be great if the OP could do a flow rate for us, it seems he would want to know for peace of mind. This would be a much cheaper way of doing a bypass sytem!! Although I will have some quality hydro hoses made at the local hyd shop. Please keep us posted as to what you find out and I will do the same.

Well I just got my reply from Amsoil. Just as I thought the regulator is in the mount not the filter. Using the filter in a full flow mount like the one on Ebay is not the right way to do a bypass. To the OP, you need to either regulate the flow down to about a quart per minute, which wouldn't be to difficult, or pull this thing off your engine. At the rate the oil is flowing you are starving the engine of needed oil. I knew it had to be this way otherwise folks would just buy any old mount and use the Amsoil filters.
I reckon I just need to save up and purchase the Oilguard unit.
Here is the reply from Amsoil.

Kevin;



The flow is regulated by a restricting orifice in the mount itself. It is screwed into the threads where the filter screws on to the mount.



Thank you for this opportunity to respond to your question(s). As always, please feel free to contact us again if we can be of further assistance.

That's what I thought, Tonite when the truck gets home I'll check the flow. I went with smaller hose barbs for this reason. I may have to restrict more.

Thanks man, I think once you get the flow rate correct you will be good to go.

Good to know! Easy fix thankfully.

Wonder why the EABP120 restricts flow and Amsoil says that others don't?

If I need to, I'll braze up one of the hose barbs an then drill a little hole. Stock oil pressure guage reads the same as before.

Anybody know what the typical flow rating (ft^3 / s) is for a stock full flow filter? Just wondering because if we know what that is, then you could figure out exactly what size orifice you would need to get a ~10% by-pass flow.

The best flow rating I can find is "About 15 quarts in 10 seconds", not exactly accurate.
