in tank fuel pumps
I am thinking of fitting an R1 in tank fuel pump into my fuel tank rather than have a seperate pump mounted somewhere at the rear of the car.
Is there any particular reason people use seperate pumps rather than in tank?

Mine is in the tank (from the bike). It seems to work well and is one less thing to plumb and fit somewhere in the back end. I have no idea why some
people shy away from doing it...

I would say just the fabrication part. It's easier to use a standard tank and a 10mm take off to an external pump.
No need to use an internal pump for a carb'd engine - the R1 only went internal when injected.
I plasma cut my 'swirl pot' base out of 12mm ally plate to recess the pump, then TIG'd it in.
I suppose not everyone has this option.

the engine is injected and it was the in tank pump from the bike I was going to use.
I have a square sump on the bottom of the tank with the outlet coming out of one side. I was planning to use the original outlet as a draining point
if I ever needed to empty the tank then cut a hole in the bottom of the sump part for the fuel pump.
Anyone see any problem with this?
The only thing I can think of is the thickness of the aluminium and fixing the pump to it.

I used a Landrover jobbie - pump, swirlpot & sender all in one.

That's a nice looking unit - which Landrover? and how tall?

RazMan, any idea of the sender hole diameter, needed in the tank? Thinking about future proofing for latter EFI install, without the need to cut a
tank that has had petrol in it..

Unfortunately I can't get to it without dismantling half of my car but I seem to recal that it was around 120mm diameter like an Aero cap but
bigger. You need to make a fixing ring that secures it on the inside of the tank with a rubber gasket (supplied with the pump iirc)
