Dedicated Oil Metering Pump

[DixFD]

Hi all.

Looking at fitting a Ryan Rotary oil metering pump kit.

1. Will it suit stock twin turbo? Is there enough room for the sand

2. Will it suit the 13b-REW motor??

It always seemed to making sure the tank had enough head height to guarantee supply (plus you will want a level alarm too)

Hi Shaun,

I know about the rotary aviation pump, I'm just fed up of paying the import duty for US.

I personally like the idea of it, with a level sensor and regular maintenance I don't think it will be anymore of a hindrance that the stock item.

I was just making sure the one pictured is the right shape for a Twin 13BREW and would actually fit in the space available.

Cheers

Not sure if the Renesis and REW OMP bolt pattern is the same, have you emailed Ryan Rotary?

I don't understand why you need this. What's wrong with chucking it into the petrol tank?

Why would you have it squirted in via two little tiny holes? What if there's a blockage or a leak?

Amen. You don’t get full coverage of the housings/irons so end up premixing a bit anyway. Just add a bit more.
And don’t worry about decel as it creates a film.
One less thing to go wrong.

Yup just premix. With no omp you want 100ml of oil for every 10l of fuel

Seems like the popular opinion is to just premix. Is there a blanking plate available for the OMP?

Mine is leaking from around one of the banjo bolts anyway, so might just delete it and premix like a trooper.

 

[Nas80]

Yea im sure there is. I made my own though

Essex rotary do one. £25 delivered.
Get 2 x m10x1.5 bolts to block the housings. Cut them down to size

 

[jack.am]

Do not cut bolts down to size for the injector holes. Buy proper length grub screws.

 

[Adam]

What’s wrong with a cut down bolt? Put a copper washer on it. Make sure they are a bit shorter than the oil injector thread.
Nobody can see it.

I thinks that's only because the bolt is bottoming out in that pic. If it's short enough shouldn't be a problem

You need a head on the bolt any way as it's a parrellel thread so needs a washer to seal. Should be no ptfe tape in sight!
