I am looking to replace the oil line feeding the turbo so it can be rerouted out of the way and am unsure of the size of the hose. I think it is -4an but remember seeing someone say -3an and wanted to check before I am $100 deep into line and fittings. I am sure someone had to replace theirs to get a better routing thru the engine compartment.

 

I found an email from Rodney when I asked about the red restriction block and he said that Precision said it was not needed if an -3an line was used.

Also found a 2nd email talking about the relocation of the sending unit and it also discusses -3an fittings.

Sorry for being so vague but I don't have anyway to size these fittings either.

 

Are you still running the oil line the kit came with? I thought someone extended theirs.

 

Yes I am. What I did was get a short piece of braided line and ran it from the block to a tee where I put the oil pressure sending unit and the line for the turbo.

 

Here are some quick pics

 

Thanks for the pics. I keep looking at these -4an nitrous lines with the pre connected ends but don't know how they would hold up to hot oil. I will email Rodney about the size, it looks smaller than -4an. I really want go do the black nylon braided hose, but -4an is as small as they make it.

 

It just dawned on me that I have the invoice for my meth kit.

It also has SST braided hose that is -4 and the oil feed line is definitely smaller. So I would say it is a -3.

 

Definetly feed line is -3an we highly recommend ..hi speed do you need a longer length ? I can just send you a piece to add on eliminate replacing whole line
