Fuel lines revisited (Yay!)
Turbo Mini Forums

After trawling the wealth of knowledge on this site, I have answered most of my questions regards fuel lines sizes. The one thing that has been asked already but not really answered is:

OK say your running 8mm feed and 10mm return, how do you get around that fact that you have 6mm inlet and outlets on your regulator/tank/pump? Do people mod their regs/tanks/pumps to suit their lines or will this not really remove from the flow potential of your nice new lines? Also what do you do about fitting 10mm (I presume ID?) lines to 8mm OD fuel regs etc?

I think that is eveything I need to ask. :)

stretching!

Its a pain! heat up the hose in hot water and stretch it over a tapered bar. wd40 may be your friend when you try and put it on the 10mm pipe

Ahh, I think I see where the problem is, when people refer to 8mm or 10mm they mean OD then? So the ID of a 10mm line is smaller than the OD of the reg then?

no, measurements should be the id of the hose

what i think jay is getting at is that a 10mm return hose will be loose on the reg and tank unions

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

"did you know you can toast potato waffles?"

Yes that is my thoughts but with the reg securely burried in my box o' parts that are not yet fitted and my fuel lines not yet purchased maybe I should wait till I have them in my hand before I get ahead of myself. Also with a lot of posts talking about fuel line sizes etc I just wondered how it all worked since the outlets of the reg will be smaller than your 10mm return and will limit flow? Ya get me? Basically is there any point in getting bogged down with IDs and ODs and returns being bigger than feeds when the reg and tank unions are all the same size?

there is nothing wrong with a A-series that a turbo can't fix.

I answered your PM paneermeel but basically I ran a 10mm ID return even though I had to step the ends down to 8mm to fit the fuel regulator and tank. If I was to do it again I think I would T the return into the feed just before the fuel pump.

Like you said in the PM. It seems silly to use 10mm ID lines and shrink them down to 8mm at the regulator and pump.
I will have a look at mine pump and regulator to see what the max size is that i can fit to them. Maybe the 9,5mm ID will be pefect.
