Yes.
I fitted one, but only after carefully checking the welding and doing a pressure test. I can weld reasonably OK (ie functional), but I also know enough about how it should look to see the Davefab welding is a lot better than mine.
My only two quibbles are
- The seat for the pressure cap seal has sharp edges and will damage the rubber seal, so I dressed it smooth.
- The overflow spigot points differently to the OEM , so just reverse the overflow tube. As with the OEM remember to swivel the free end to point up when topping up the tank.
This shows the welding and sight glass. I also made some poly washers to prevent damaging the paint and to allow a bit of float with heat cycling.
I took off the label later.
Here is a phone-pic taken just now, still with evidence of sahara dust!
