This was done for 2.9i conversions to two Scimitars in at the moment. They are to replace a terrible swirl tank installation on both cars, one of which is here..

Not my work, if that wasn't obvious!

One is stainless, the other is mild.

Nice work on the tank
these pumps often come with a metal sealing ring coated in green gunk. if you are fitting the pump with one of these then I suggest you take it out and throw it away and replace it with an original cork gasket. Because
1. it will stand a better chance of sealing
2. it won't drop loads of bits of green gunk into your fuel tank
The last one I fitted returned quite quickly with a complaint about fuel smells and when I investigated I found the bits of green stuff floating in the tank

Out of curiosity, what is so terrible about that setup?
Just be careful your cork gasket uses a nitrile binder, or you'll be back to square one again.

It does. The return feed is the other side of the tank.

New cork gaskets are fitted. Pumps don't come with them and EBay sellers tend not to even have them. I went to Manners in the end.

A) It stops the spare wheel being stowed in its factory position.
B) Having all that fuel system next to the engine is a fire risk.
C) It is expensive and looks appalling.
Mind you it is not as bad as the other car... All that swirl tank and pumps assembly is inside the car, with pipes running in and out of the body!

Ah. I was worried there was a *technical* problem with it (I have pretty much the same setup but I'd not got as far as running it).
I think the work you have done on that is great and I am not surprised as what you share is always good. So, keep it up.
Perhaps I have a strange sense of humour but, the idea of eliminating a fire risk by welding a used fuel tank did make me chuckle.
While some will question the wisdom of updating a classic car with more modern features, I think it's a tribute to the general usability of the Scimitar that people do such updates.

Nice work, looks like a neat install.
You don’t need a return, a few slightly more modern fuel injected engines don’t come with one from factory (rover k series turbo as an example off the top of my head) they have a vacuum controlled regulator just before the fuel rail, which surprised me…

another reason for this is a high pressure pump on the engine itself feeds a rail that regulates back to the pumps feed pipe hence no need for a return

Most EFi have one, including the 2.9i Cologne. That switches pressure between 2.5 and 3 bar according to the vacuum.

Never bothered using vacuum to my fuel pressure regulator on my Xflow engine in my kit car , it was set up by Emerald , Dave Walker mapped it accordingly even though he’s not a great fan of bike throttle bodies because of the throttle opening so quickly on initially pushing the pedal down . Have since fitted a progressive throttle mechanism to smooth out driving
