Title: Aluminium fuel hose and fittings Post by: UltraOrange67-2443 on July 04, 2014, 14:00:52 pm Thinking of running a aluminium fuel hose from my filter (after pump) to Y piece on my EFI system.
Anyone know if the fittings can take the pressure? The type with a olive and no flare are only rates at 50psi. Cheers, Nick Title: Re: Aluminium fuel hose and fittings Post by: spoolin70 on July 04, 2014, 17:40:05 pm Are you talking about aluminium hardline fuel hose ?
Goodridge and Krontec both make some. I've got the Krontec and although I don't know the rating, I've had around 140 psi through mine with no leaks. Thanks Darren Title: Re: Aluminium fuel hose and fittings Post by: UltraOrange67-2443 on July 04, 2014, 21:19:47 pm Are you talking about aluminium hardline fuel hose ?

Thanks Darren Hi Darren, Yes hardline, I've looked at the Russel lines and compression fittings. I need 1/2" for -8 and 3/8" for -6, Krontec are metric.

According to this : http://www.interex.co.uk/motorsport/content/assets/Goodridge_Hardline_Cat.pdf ,the working pressure of the aluminium tube is 1375psi. But that's only 8mm bore which would do for the -6. From memory (I looked into this a while back), 10mm bore for -8 is harder to find.

Thanks Darren Its not the tube but the fittings I'm worried about, some say for low pressure use only. Fine on a Carb motor but not for EFI.

Title: Re: Aluminium fuel hose and fittings Post by: Andy Sykes on July 05, 2014, 21:52:00 pm Yes nut and sleeve and over 500 psi so should be fine for fuel pressure lol
Title: Re: Aluminium fuel hose and fittings Post by: spoolin70 on July 06, 2014, 00:00:33 am Ah yes I understand. Pointless having a 5000psi working pressure line if the fitting is only 5psi rated huh.
Andy - is any of your lovely pipework 10mm bore ? ,or larger ? Thanks Darren Title: Re: Aluminium fuel hose and fittings Post by: Andy Sykes on July 06, 2014, 08:43:26 am An6, an8 and An10
