Disco 1 v8 fuel filter thread check please!

Dunno.... but an 8mm fuel line (ID or OD?) Can only supply 'x' amount of fuel, the banjo and bolt holes would be sized I would have thought? The only issue, if it even is one, is the 90 deg turn of flow at the banjo itself. It's worth a try, the bits are cheap enough.

Definitely worth a try, and if good, banjos would make a good repair option when the factory fitted glands eventually seize or leak and have to be cut off the fuel pipe which is not unknown I believe.

nope, wouldn't work with the length of banjos bolts on there - they wouldn't seal up against the washer. then I;d be switching to a carb spec filter and all that crap... I want to keep this as standard as humanly possible. If I can say that the end of this that everthing is either 1998 300tdi defender 110 or 1994 v8 efi disco1, then I will have done a good job. The addition of 2 adapters and some viton seals still seems the simplest way of achieving this.

You could cut the banjo bolt down/add more copper washers?
Or
Thinking outside the box, drill and tap a banjo bolt head 1/4 bsp? To take a standard bsp hose tail (available everywhere). You could put a suitable spacer on the bolt to replace where the banjo would normally be?

Is the fuel line nylon?

Is the fuel line nylon?

Fuel line is "R9" spec rubber fuel hose. Suitable (internally) for modern petrol and high pressure. It is not, sadly, submersible in fuel, as the outer coating degrades.

Sawing off banjo bolts etc doesn't fit into the standard ethos. If It can't be done with the standard disco filter then I'll have to find an aftermarket one with different connectors (as mentioned a few posts ago).

Nylon fuel line (compressed air tube is what I've used) is everything proof and is rated to a minimum of 10 bar. The reason I mention it is if you did tap out the banjo bolt you could fit a 1/4 bsp male to 10mm compression fitting into it. Tidy job and easy filter renewal.
I've done this on my 200 TDI and my camper van.
