You might want to edit that as it made no sense at all.

An 044 intank is no problem if you use an additional sock filter on the inlet. Orientation isn't an issue with it at all.

If anything I would be more worried about the limited filtering capacity of the 040 pump filter screen.

The 044 does have an internal filter screen as well, although the mesh might keep out things like.. medium size rocks perhaps?

My question was pointed more at eXc as he has reported 044 intank failures and I was wondering if he had used an additional pickup filter, but then having one bad out of the box I probably would have been asking more questions of the supplier, than the pump install itself.

SECUR1TY's install is an 044 and they dont like being in a tank at all.. the ( 040 ) has a filter built into the bottom of it and they are designed bo be used in an upright position unlike its 044 external brother..

so if you are using in 044 in your tank no wonder it died...

Quick query:

Heatshrink. will it react with petrol.

I only ask as I soldered the connectors on to the wire, but it looked messy, so I used heatshrink around it, then on the terminals too (figure that avoiding a spark in the tank isn't a bad idea)

Anyone know if it'll perish or even worse, heat up?

I did a quick test with some fuel and a strip of heatshrink, and nothing seemed to happen, but just thought to ask.

alright i am in the middle of doing this now, and i can't for the life of me see how you can put this in without cutting the metal pipe that the pump connects onto via the hose

it is simply too long...

Good to see a tutorial on this but there are several issues I see over looked all the time.

A. 040 and 044 are massive over kill unless you are looking at supplying fuel for a hugely powered car. (in which case, an in tank simple set up is lacking in every department)

B. no check valve on either of these pumps. So as soon as you stop the car, all pressure is lost.

C. I don't think I've had an R32 that you could bend the pump seat down and fit it back in

D. this mounting style will be tremendously noisey.

Not being a smart arse! just trying to give info that I have come accross the hard way. I recently revised my in tank bosch set up but the pics are on my work computer. I'll get them up soon.

Thanks for the comments, other peoples experiences are always good when doing something like this. My views however;

A) It's what 'everyone' on the forums here seemed to go for, which is why it continues to be a popular choice (even though now I'd say buy a walbro, cheaper, i had less problems and it would fit in the standard mount)

B) No idea about that, but it didn't cause me any problems - Unless that had something to do with me going through 2 of these pumps...the walbro never had a problem... so it could be? not sure why I went through 2 Bosch's cause the tank was not contaminated.

C) Like I said in the tutorial, you need to cut it down.

D) Wasn't noisy for me at all. The Bosch was much louder than the Walbro however.

Cheers

I just installed one today. For some reason if I was to mount mine directly under the fuel feed pipe it would not fit in the tank. So I mounted it on a very slight angle and put a loop of hose around back to the feed. This actually worked really well. I only have 10l in the tank and its fine, its only slightly louder than the standard pump.

I also did the fuel pump rewire because the standard pump was getting just under 12v.

I have heard that at low throttle position (less than 10%?), the voltage drops to 6V to cut noise down. Is this true? If it is this may be the reason some peoples pumps don't last long as they are burning out if they are using the factory wiring to power the pump.

Mine was around 12v mark at idle...so i don't think that is true, unless it drops voltage when you throttle it a bit, which I doubt... measure it for us and let us know,.

Were you measuring voltage from the positive terminal on the pump harness to chassis ground or the negative terminal of the pump harness? The voltage regulator module for the fuel pump lifts the ground to reduce the voltage seen at the pump.

      FWIW a lot of the local owners that do a big build tend to have cars that are perpetually broken.

      R34 GTT Battery Relocation To Trunk

      I just got this system but haven’t installed yet I got a Moroso sealed box (defect reasons) which will be set up same as their pic The quality is high grade, the correspondence I had with the owner (former head designer for Rockford Fosgate) was unbelievable, guiding me with what I needed. Even told me not to buy some things as it could be sorted in a different way at his loss. Just a bit of a bite with the exchange rate and don’t purchase gear in 1 hit that goes over $1,000 au, lol I forgot!

      Rv37 400r questions

      By elir32 · Posted

      Thanks mate for that reply. Very helpful.    it’s a 2022 400R so would most likely lose those features as you say.     I did a quick compare of a rv37 nav and heading for sale in Japan to q50 model. I’ll pop pics below. Seems  Japan spec head into top, nav unit second below it   below pic Q50 aud delivered     differences seem to be Aus delivered has a different plug top left hand side of head unit- not sure what and where it goes.   and nav unit Japanese tv37 had an extra plug put    Again I’m really not sure what each of these differences mean!       the actual plugs on a v37 and q50 screens look identical on both screens… pics below for comparing. (One screen was is a us delivered one) but should be same gps signals etc as Australia.    If it were as simple as swapping a nav unit from q50 aud delivered im interested -just want to figure out what the missing plug is for before spending big $ on a second hand part for it to not work, and I guess with the head unit, if the band expander does the job (I got a 20mHz so should get the range I’m after) so should narrow my issue down to nav unit only.  I’d love to know what the extra cable on rv37 does and if I eliminate that part what it’ll do to the setup,    and also, if I can figure out what that head unit plug difference is, what does that cable do and where does it got can it be altered or re-plugged?! Excuse my ignorance what is ACP/AA, what does that stand for? (Apple car play? Android air play)? so If I swapped head units to save using a band expander, I’d likely lose those better features to have an oem Unit operational. Better to use a band expander and retain AirPlay options and newer version of head unit     provably best to band expand it, and focus on the nav unit. th isn’t  a big deal/ would be cool to have it working  from what I can tel we use a PAL Signal and Japan uses a NTSC signal  I don’t know if there’s a co better or if the screen only reads NTSC, or if it’s the tv module that needs replacing… no big deal don’t need it but more of a curiosity thing on that!   Thanks for the info re tyre sensors, helpful and great to know.  I was reading the online manual off Japan website and it seemed to make it sound more confusing than it is  I guess a rim replacement would require the sensors to be moved to a new rim to carry that option over?!     Thanks for the info regarding diagnostic mode. I appreciate your help mate. Trying to brainstorm here to find a solution to get as much gadgets as I can working! I plan to get my local Nissan tech to have a look too who used to be at an Infiniti dealer back in the day to see if any thing they have or idea can find a soliton. But hoping anyone here has gone down the same route to make life easier!!   i guess identifying the cable/plug differences and what they do would be a great way of finding out if the units are transferable    thanks again

      Rv37 400r questions

      By sonicii · Posted

      No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.
