On the L26 they started used a mechanical fuel pump supplemented with an electrical fuel pump. Do you need the electric fuel pump for the vehicle to run??? Or does it just need it for performance (I read somewhere it only kicks in when the engine revs high???). I haven't taken it apart, but it hasn't run in 10 years and I'm thinking either I might need to replace it or at the very least replace it's filter. MSA had an electric fuel pump stock replacement for $200+, but there was a electric fuel pump in the performance section for $60+. Is that fuel pump supposed to replace the mechanical fuel pump? Or can I use it to replace the electric fuel pump by the fuel tank? Or what would be the best route (pump wise) for me to get my 260z up and running?

You must have the early carb type 260. No the electric is not manditory.The mech. type will work fine.The mech. type is not manditory either!You can use electric!Confusing isn't it!You can use one the other or both.Although if either is bad,I don't think fuel would pass through it so it would need to be removed/replaced.Those supplement pumps did supply enough psi didn't they guys?

The main reason the electric pumps were first put on the 73 and later carburated cars was to help cure the vapor lock problems they were having.

You can use either/or when it comes to pumps. My advise would be to use a good electric pump (doesn't have to be the most expensive) with a pressure regulator and do away with the mechanical pump. Just get a block off plate and take the mechanical off completely. It is a bit redundant to use both IMO.

I'm not positive about this but I think you should run somewhere between 7-9 psi fuel pressure, but you might want to check with someone on that. I think you may have float problems if you run with too much fuel pressure.

Thanks for the info guys Is there any fuel pump out there you could recommend? I've been browsing through some of the NiSMO links on this webpage and saw some performance fuel pumps, and I've got Victoria British and a MSA catalog... any suggestions?

Any electric pump should work, however you may have to do a little work to mount it since it may not just bolt up to the stock mount. Just make sure to put a pressure regulator in the line and make sure it has the right inlet/outlet line size.

I guess the only thing to consider is how much you want to spend. You might call MSA and ask them if the 60 dollar pump they have will work without the manual pump and go from there.

Thanks for all the feedback guys, this webpage is great, it's probably saved me loads of money already just reading the articles aswell as getting feedback from people.
