oil metering lines

how much psi do the lines hold. i need to konw because i going to make my own. mostly to see what i can use for clamps.

thanks

Do this:

I had everything ready to do it myself, but then I decided to go strictly premix. The line and clamps are cheap. It's a good setup for using the stock OMP.

if you havnt replaced them yet, go to ace hardware, go to small engine section look for fuel tubing int the correct inner diameter. the best stuff to use is the pee yellow colored stuff. its kinda pricey... i paid like 13 for 7 feet. its oil and fuel resistant and heat resistant up to 350'f.
i used hooby level zip ties from hobby town usa, the ones they use for
nitro powered rc cars the can get up to 300'f and not stretch or warp
trinity makes them... in multiple colors

kinda funny how much rc cars and small engines have in common with rotary engines
loud, high pitched, oil burning, high revving.....pre-mixing
come to thing of it they have a 1/10th scale rotary wankel nitro engine.

True, but Hailers tested the OMP on a running engine by connecting a pressure gauge to the end of one of the lines and found the OMP could make ~40psi of pressure.

Me? Argue?? Never!!!!!

I agree (as in I'm ot arguing

) with you that normally there is very little, basically zero pressure in the lines. I'm just pointing out that the OMP itself can make more pressure than I thought it could, which from an engineering standpoint makes sense. Basically I wouldn't use vacuum tubing and zipties. The Goodridge SS braided lines that I have are overkill sure, but yeah, the crimped braided lines that came with the motor were leaking.

And everything is an arguement with ted, becuase ted thinks that ted is always right. Even when I can mathematically or empiracally prove ted wrong, even on a technicality, ted is always right
