T Piece Instead Of Tank Return?
Turbo Mini Forums

Ok, I've just read the thread below entitled 'first time starting'

It briefly mentions using a T piece instead of a tank return.

However it then says that said T pice would need to be fabricated due to differing sizes.

Ive just seen this on the Bay:

and I am wondering if it would do the trick.

I understand that it is larger than the tank outlet, same size as my fuel return, but smaller than my pump inlet (metro turbo item)
but i was thinking it would be ok.

Any thoughts guys?

Cheers

Gaz.

i'll stick my neck out and say it'll be ok as its the same size as your return. If i'm right then after 18 months of reading and learning from this forum, i've given my first correct tech advise lol

If you are using it on the turbo fuel system it`s no good because you do not want back pressure on the return fuel to the tank

the T would go between the tank and the pump, its a subject that been brought up a fair few times and the exact reason WHY is it works i'm a little vauge on, but i'm pretty sure its do do with the return pressure is lower than the feed pressure therefor fuel return is also under a certain amount of suck from the pump. Could be wrong.

but doing this will play about on the pressure reg on return fuel when on boost

would you want to use 1+ one way valves to stop fuel flowing the wrong way?

I cant see it interfearing with the pressure regulator.
Hasnt someone on here used this setup?

y yeah a few do, just doing some searches to dig them out.

thats how mines plumbed in and its fine. jukka sent me a diagram of it ages ago when i was first turboing my car. its been running fine for the past 2 years now and keans just done his the same aswell.

what boost you running ?

10psi most of the time but it's been up to 15 a few times...

I ran like this at avon park last year - It did the job perfectly

Im gonna give this a try, just ordered one of them metal ones too.

i got mine and the two 'though' connectors are 8mm and the 90 degree one is 6mm. Will that cause issues if i'm running 6mm feed and 8mm return as that T will cause a restriction.



I'm thinking it'll just be easier to get the tank done lol

I run 8mm feed 8mm return

Hi,
I don't think that tee will be big enough. The pipe between the tank and pump will be 12mm. I can't see a problem with feeding the return into the suction side of the pump as there won't be a lot of pressure in that pipe. When it's plumbed in check your fuel pressure at the carb, you should be able to get it down to about 0.5 PSI. If not there's too much restriction in the return :(
Cheers,
Gavin. :)

My Mini build diary

i made mine out of brass the inlket to the pump i made was 10mm with 8 mm return and 8 mm from tank works a treat

always looking for them bigger bunches of bannanas

i think you might have the 6mm and 8mm measurements the wrong way round?? or im really confused...

"Turbo's make torque, and torque makes fun"

"did you know you can toast potato waffles?"

just remeasured it across the inside diameter of the unions.. the top two are 6mm ID, and the bottom one is 5mm ID
