M35 Aftermarket Fuel Pump

[cha_cha_]

so my m35 stagea didn't start the other day. the normally noisy fuel pump is clearly not priming when i turn the key so i'm almost 100% certain that it's dead. I've pulled the plug on it and checked that it's getting 12V (which it is) so it's a pump problem, not an imobiliser or supply problem.

Sorry for the fresh thread, but I've searched and i'm still not entirely sure what the best way to go is for a replacement. I found nissan factory replacements for ~$400, too much info on scottym35's twin pumps, but nothing concrete on the "right" way to just replace my factory pump. I'm not modding anything else at this stage so just a standard or slightly better pump is fine for my needs.

I'm thinking walbro as i understand i can just get the walbro 255 GSS342 for 350z or infinity and retro fit it with minimal complications - is this true? what about the bosch 044? is this a similarly easy installation?

also, where's the best place to source one? i'm in no rush so i'm happy to buy online and wait a week or so but i don't want to get an ebay fake like the ones that were floating around a while back. can anyone recommend a good local or international store?

Any advice on the installation? i'm keen to do it myself to save on labour and towing but obviously playing with the fuel system is something that i want to get right...

Thanks guys

I can get a Walbro through my Aus wholesaler for under $140 I think so shipping from the states probably isnt worth it. There are definitely fakes around so be very careful. It will need slight modding to install and you will need to rewire the power to it as Walbro's need constant 13.8V.

I have a factory pump here if you need one. PM me. I cant guarentee how long they will last but mine wasnt noisy when I took it out...

Where are you located?

[cha_cha_]

located in sydney's lower blue mountains...

looking at a few guides for installing walbros into 350zs (i can't find a guide for an m35), a factory replacement would be good. i have the skills to do the job, but i don't think i really have the time to get it done on the weekend along with everything else i need to do :\

same size and stock (apparently, thats on a c34 but i believe that m35 uses the same size) but 300lpm and a higher pressure than the walbro pumps

[scotty nm35]

Ours is the same as the G35 other than the return line. The how to Duncan posted will show you how to fit a Walbro but obviously you wont need to mod anything for a factory replacement.

Yeah I was looking at doing the Deatschworks pump. Is that what you're running Tom? Looks like they're the same size as a Walbro, so the fitting etc should be the same.

Is there a filter worth replacing at the same time? I thought there was a screen or something?

[scotty nm35]

Theres a sock and a filter.

[bigkevracer]

Cool. Worth replacing then?

[scotty nm35]

Leave the sock, just clean it. The filter will need to be replaced, I dont have the p/n handy though, perhaps Cam or one of the other guys has it?

Hey mate; I'm at Faulconbridge! Is yours the White Aero kit that I keep seeing around Glenbrook?

If you need a hand, or feel like a chat (or beer); shoot me a PM yeah?

Cheers, Dale.
