oil cooler line question?

ok heres the deal....my original gsl-se cooler cracked couldnt get it fixed and my buddy sold me a 2nd gen cooler for 20 bucks but no lines or banjo bolts so i finally found some banjos at a junk yard but they were chopped right where the fittings ho into the block were so...heres my question i got a barbed end that can go into the 2nd gen hoses that thread into the 1st gen hoses so if i jam the barb into the hose and double hose clamp it will it hold??? i went all around town 2 places that made hoses but they wouldnt crimp onto the 2nd gen hose saying its not strong enough or somthing..... bottom line is they wouldnt do it no1 would so would it hold???
it sounds risky 2 me but i dont have any other choice im a lil broke right now 2..anything besides a smartass comment would work thx

I find it odd that they wouldn't crimp ferrels for you. The barbed ends will need to be brazed on the metal tubes coming off the banjos, perhaps that is why they said it wouldn't hold. Make sure the hose you use is presuure, temperature and oil rated, they should be able to supply it. 1/2" barbs and hose fit nicely.

If you have not read my write up in the archives on the 2nd gen fmoc install, do so. It covers the line issue. When I went to the hydraulic shop, I took all my hard parts in, carefully explained what I was doing, and let them choose the correct hose, barbs and ferrels. They know what works for the application, I didn't at the time. My total cost from the shop was under 50 bucks, parts and labor, only the lines went to the shop.

If you removed the barbs, you will need new ones brazed on.

I encountered major issues trying to get a local hydralic shop to assist me in making new hoses for my 2nd gen cooler conversion. To make matters worse, they had just bought out the local competitor. They wanted to cut the original barbs off, and braze on a $25 fitting (X 4 = $100), then use hose that was overkill.
I ended up going into a shop that caters to racers. The guy that owns it, fixed me up without any hesitation. If the local hydralic shop is not giving you what you need, try a speed shop. They will have a workable solution, that is also affordable.

I would hate to trust a hose clamp. While it may hold for a while, a failure could lead to a catastrophic engine failure.......

Other than a liability factor, I don't understand why they won't perform service. If they use thier own barbs, ferrels and hose, this should be a non-issue. If you are attempting to save coin and use parts that are not compatable with thier's, I can understand thier refusal.

Go back and ask tham what will work and if they are willing to do the work. Tell them the hose will never exceed 125 psi, 300* and needs to oil rated. The #s are the limits of what will ever be seen and most any hydraulic hose greatly exceeds these #s.

This is not an item to cheap out on. If your warning buzzer in non-op, you could easily destroy all 4 main bearings and e-shaft before you notice the low oil light. Don't ask how I know.

This is where I get OC, brake and A/C lines for less than $75. Unlike mazdatrix/racing beat prices, there is no need to change the end fittings and it doesnt crack.
