oil return hose sizes

[caseys]

Hi,

 

I'm looking to buy an aeroquip FC333 hose from thinkauto.com to have as my oil return hose from the turbo to the sump.

 

Does anyone know what kind of fitting is required for the sump end? Thread diameter etc... as would really like to get connectors rather than push on + jubilee clip.

 

Hoping someone does as it's a pain in the *** to take the turbo off, hoses and all to find this fitting.

 

Cheers!

You need a special fitting, it's a flange with two bolt holes that you bolt it to the block with and normally a 1/2" NPTF threaded hole in the middle. Then you use a 45 degree male-male -10JIC to 1/2"NPTF union screwed into that fitting and your return hose screws into that.

 

Not sure where you can get them other than in the oil hose kits.

You really are a walking Supra encylopedia Simon...

 

Thanks again for your help (it's probably the 100th time I've said that now...)

I made up my own fitting. From memory it was out of 10mm thick ally, with an M22 hole. I then Got an M22 to -10 fitting, and then hooked up my -10 lines.

It's often better to use hose clamps and decent high temp hose, on push on fittings for this application. The thing you are after is maximum flow, under gravity. So what you don't want are the diameter reductions screwed fittings create, especially the cheaper ones. There's no pressure to worry about, so a formed, thin wall steel or alloy pipe, swaged, with push on rubber hoses and Jubilee clips each end is fine, cheap, and with the correct formation of the turbo drain and block fittings, will have less flow restriction than about 75 quids worth plus of Aeroquip stuff.
