A while back I remember seeing a company that made upgraded oil metering pump lines that are not steel braided so you can still see if the OMP is still pushing oil. A recent google search didn't bring it up. Does anyone know or remember the company I'm trying to find?

 

Why not just get new stock lines?... they are formed to fit, and if you replace now will last a long time.

 

they are also transparent, so you can see oil moving...

 

Yes, I know, but if I remember there was a company that made transparent lines that the plastic was better and therefore less likely to break over time. I'll go with the stock ones if I can't find the upgraded ones.

 

^ Just go with stock, it is easy and fit perfect.

^ Yep I used the info on that same thread to make the lines on my 20b.

I have been running these and have no issues. Not to mention the piece of mind of steel braided lines.

 

I made 321 stainless hardlines for mine

 

Hard lines everywhere!!!!

 

The stock lines will easily last 100,000+ miles. The stainless braided lines seem neat at first, but -

- they cost substantially more
- they aren't formed to fit all the twists and turns
- braided stainless is VERY abrasive and will rub through pipes, wiring harnesses, etc.

IMHO there's no good reason for it. Not to mention those braided lines will probably be in just as bad shape in 100,000 miles.

New lines are super flexible and nearly indestructible. The only time they break is if they have a LOT of time and mileage on them and someone physically moves or twists them.

I would not spend more money for something that fit worse, was highly abrasive, and is a "maybe" if it would last any longer.

They are actually pretty inexpensive, 98.00.

They are also coated so they are not abrasive at all and plenty long to make all of the twists and turns. I have had no issue with mine and they have been on my car for 8+ years.

 

those hard lines tho

But yeah, just get the OEM ones from Ray...keeping it simple

 

My, but your lines... they are so... hard everywhere.

The stainless lines are a bit of hassle to route since they're not pre-bent. But not that bad since the engine was on a stand. Either version would be a lot harder with the engine in the car. And I did have to split an old rubber hose and wrap them in a couple places so they couldn't rub on anything.
But I see no reason they wouldn't be in WAY better shape than the OEM lines after a 100k. And my OEM lines were so discolored you couldn't see if anything was moving through them anyway.

 

Not to menchion not knowing if your OMP is flowing or not. You can always see the lighter oil tone in the clear lines after an oil change.

 

I'm a bigger fan of your fuel lines.

 

Yep, I agree completely. I too did the stainless braided lines when I rebuilt my engine, carefully noted and then covered any potential chafing areas. And yeah, the stock lines quickly become discolored to the point you can't see anything, anyway.
