Anyone know where to get fittings for series III tank fuel line? I am putting one in drivers side of my 73 series I and would like to use the original metal fuel line instead of the fatter SIII hose, as it's going to the mechanical fuel pump.

Just went to Napa Autoparts but no joy there.

 

Hope you have the later filler caps to go with the new S3 tanks?

 

yep

 

Is what you are showing what you need? That looks like the fittings out of the Series 3 tank.. One that is the larger supply line and the other return that goes across the muffler... I have those I think.. Or are you looking for something else..
(Email me if you want - EverydayXJ)..

Hi David - I'm looking for a fitting that fits the SIII tank thread but will allow me to plumb in the old series I fuel line, which is a smaller thread. The fatter shorter fitting in the pic is the SIII fuel injection fitting, metal fuel line is the SI, which is what I want to connect to the SIII tank.
//That XJC door was perfect btw, thanks for that!

 

I'm confused, you are asking for the fittings but you have them already? Or is this someone else's images?

A salvage yard/breaker is probably your best best. You will likely have to talk to someone because its a random part that wouldn't be listed online.

 

The fatter fitting is what was originally threaded into the SIII tank. It has a spigot to attach a rubber fuel line.
The longer metal fitting is what was threaded into my original SI tank, which I have removed due to rust and holes.
what I need is something that will screw into the series III tank but allow for the thinner metal fuel line which goes to the fuel pumps under the boot/trunk floor.
Somewhere out there is a threaded male connector/adapter that will allow this, and it won't be an original part ...

 

What you are searching for is a flare reducer bushing. Try searching Parker Hannifin fittings on line catalog. Another good source is McMastercarr.com> you may have to use a couple of fittings to get to where you need to be. You could also stop by the local hydraulic shop that makes hoses they may have adapters.

 

Thanks! Good idea, I can swing by Royal Brass next week and take my two fittings and see if I can get something organized. I was on McMaster earlier in week but couldn't see anything that might work.

Cheers

 

I would advise to get back to original condition. The electronic SU fuel pumps are around $250 each. The original wiring just switches between pumps. The valves in the pumps stop tranfer between tanks. I still have my original tanks after 48 years, new pumps and lines from tanks to pump. That is all. Am sending you a pm.

 

Somehow the above post was placed on the wrong thread - apologies.

 

if your project is done do You still have some of those fittings left ?

 

Sorry if I intrude on the discussion from a few months ago. o line I've seen that any adapter can be found, even unf.
I'm in the same situation as you, I have a beautiful and original tank that comes from an xj12.
mine has two small holes
the new one has a small one similar to mine where my old cap can literally be mounted and unfortunately it is not reusable because it is stripped. the large one (I think it's 1/2 unf? ) is the same one that fits the xj6 s3.

My final question is what is the size of the little one? and above all my original metal line is 1/4 unf right?
I ask for confirmation on the dimensions so in summary I should take:

-a medium size cap
-a 1/2 unf (male) 1/4 unf female reducer for the fuel line right?

 

Roger, I used my original series 2 fillers and caps with the new series 3 tanks. I took both fillers apart to assure the venting was the same and made sure the ser2 fit properly in the ser3 tank neck while they were out of the car. The early low profile fillers look better to me so I went to the trouble of sorting this out. They essentially work the same way as far as I can tell. They're fitting and working fine on my car. Series 1 may be different but I suspect it's the same as ser 2.

 

My problem is the difference of the hole.
Xj3 and xj12 have big and medium (for return) hole
Xj1 have medium hole with adapter for small pipe and small hole
I don't know thicknes and threads.

 

Il mio problema è la differenza del foro.
Xj3 e xj12 hanno un foro grande e medio (per il ritorno).
Xj1 ha un foro medio con adattatore per tubo piccolo e foro piccolo.
Non conosco spessori e filettature
