Disco 2 Trayback, fuel tank and filter options.

Right so as some may know my D2 inside burned but quite salvageable it seems, I’ve decided to keep it alive and trayback-ish it but the tank is gone and so is all the rear half of the fuel lines, got a chassis wiring harness so that’s good.

My question is, do I try to source a replacement tank and filter housing like standard or do I switch it up? Which ever I choose, I want the fuel still stored in the same space as previously then it’ll help keep weight at the back-end.

One option is, use 1 or 2 marine tanks to house the majority of fuel pre filter and then have a 10 litre tank of post filtered fuel which is constantly full-ish as to always have a fuel supply no matter the angle etc. This would require me to fab up a steel housing to hold the tanks and keep them restrained, not a problem on that front.

Pump wise, I’d have the 10 litre post filter, but I’d end up with requiring two pumps, 1 from main tank to filter/10 litre and the other from 10 litre to the engine.
Wiring wise, 10 litre to engine pump would be high pressure essentially and wired as the standard one is. Big tank to filter would be like the low pressure, not sure on wiring, would it just get wired as above so both running at the same time but the issue is, engine return would be to the post filter tank or do I just whack that to main tank so the 10 litre wouldn’t have a chance of overflow.

Filter wise, I have no idea, ebay filter housing or stick to standard?

Just thinking of the different options as realistically, tanks are hard to come by it seems for ok money so is it better to come up with a easy to source alternative now or stick to standard, try to source the gear and don’t worry about it? Am I just overthinking and overcomplicating things as usual? lol

You are seriously over complicating things. No need for your set-up to be more complicated than the original.
I speak as someone who has had to fabricate fuel tanks for kit cars.
Why can you not use a D2 or a D1 tank? If you want a swirl pot is doesn't have to be very big.
So my advice is to stick with standard.

That’s what I thought too be honest, I get an idea and really mull it over while deciding how I’d flesh it out without stopping to think “is this actually worth doing though?” ha, until now at least. I didn’t know a D1 tank was an option, the fuel pump looks different and I’m not sure the plug/pinout will be the same. I’m not really fussed on the swirl pot, just added it in as a “if I’m doing it, why not add it” kind of thing.

The problem seems to be sourcing a D2 tank, lines and filter housing for reasonable money, as I feel like £200+ for it all is flipping steep.. probably me being tight though, lol.

Good job I joined the forum, it’s good to have a second opinion on things from mechanically minded people.

Cheers stanley.

Oops, a D1 tank would only suit a D1 engine.

Put tank in same place. Use the D2 so keeps it all standard.
Fuel cap.look at the race car/marine type these are small(make sure a diesel nozzle will fit) & this would mount under the tray back

There has been a tray back build on here
(Off for a search)

Don't worry about over thinking things. It is normal when you have a project. I reworked and made about 4versions of the spare wheel mount for a kit car and I am still not happy with it.

Righto, I’ll have a look about then, cheers!

Once you are on a project use kit car and special suppliers like Europa. Doesn't have to be race or rally as you don't have to reach their standards.

To find advert s for them get a copy of Which Kit or another magazine like it. They are a mine of information.

Will get on that and have a look, cheers!

Once you move away from standard you are in the world of "specials" so you have to think A bit differently and be prepared to fabricate stuff. I started with a cheap 2nd hand arc welding set up. You may possibly have to think about using fibreglass too. Not difficult.

That’s a standard 110 filler cap

That’s interesting, definitely gave me an idea there.. That does look good too! cheers.
