What's the in/out barb fitting size on the repurposed the Subaru filter? What's the micron filtering on it?
I know the Pierburg pump outputs 95psi, but I was hoping NOT to replace the 3/8" line after the 10u post pump filter, b/c it seems like a major pain accessing it through the transmission tunnel. Do you have any pics of your work there @edsnova? You really think 11 years of mild use is worthy of replacing all those lines?
Yes there are. Worm-drive clamps are an issue for me: they loosen AND destroy the hose when overtightened. Amazon sells these in whatever hose size you need, these are 8mm or 5/16": https://www.amazon.com/XtremeA...Clamps/dp/B0040CU0HM
The Subaru filter is 8mm which is EXACTLY the same size as 5/16". I don't know the micron rating and didn't bother to look it up for either of my filters. The standard metal can NAPA pre-filter as I said is 3/8". I figured it is a REALLY good idea to pre-filter before the pump. If the Subaru filter is good enough for a 300hp STi, it's good enough for me.
I wouldn't run rubber hose THROUGH a chassis, none of the OE manufacturers do that. Everyone runs solid steel lines. The key thing is to protect them where they go through bulkheads with grommets and/or sleeving of some sort. One year or eleven doesn't matter to me, if I can't see the line to inspect it, it has to be a solid metal line.
@edsnova what is your issue with AN hoses partway? I have black braided nylon AN for my oil cooler and also for my breather setup. I merely continued the theme. You're right that it isn't necessary but to me it looks right, like they belong there. They really weren't much of an expense.
And I also agree with Ed to use the correct hose for the barb fitting. A 5/16" Gates EFI Barricade hose will go onto a 3/8" barb, but man it's a bitch. I had thought I was using 3/8" hose on 3/8" fittings, but realized it was 5/16" after a LOT of wasted effort. DUH! Using the correct size is a lot less effort, sore fingers and swearing.
