After asking around everyone said I should be able to make a 044 fit into my R31's fuel tank. So I bought one. The problem is it seems to tall to connect any fitting onto while still leaving room to connect the fuel line. And what fitting is supposed to join onto it anyway? Anyone got some pics?

Can be used as in tank, we have done heaps.

Won't fit in an R31 though as we did one yesterday.

Swap it for a 023 which is about $50 cheaper and has a gauze on the bottom already so will fit.

I think from memory they are still good for 450hp.( based on the fact a 044 is called a 600hp pump).

Shit eh. What is an 023? I have heard of a 040 but not the 023, I have never seen it listed.

Is the 040 smaller than the 044, or is it just the shape of the bottom of the pump? The main prob is the pump is so tall, I could probably make it fit and adapt the screen but I would have problems connecting the fuel line. What made you decide it was a definite no go?

Cheers. There does not look like there is much of a size difference between the 044 and the 040 and 023 pumps.

What is the main difference between the 044 and 023? The 023 says it pumps 168lph at 5 bar and the 044 pumps 102 at 6.5 bar. The 044 is rated at 200 at 5 bar. How do I compare these as the pressure ratings are different. How would they compare in real world performance? How many RWKW could these pumps each put out? I went for a 044 becuase I am sure it will be good enough for 10sec performance for when I upgrade the turbos on my 2JZ.

What is the thing at the top of the 044, is that a non return valve or something? And do the other pumps have this? I think I can make the 044 fit if I remove that fitting. What do you think? I would still keep it in line though, just not in that position.

I fitted my 044 internally. You have to cut/modify the factory bracket, so this is a one way journey (well, you can always buy another second hand bracket if you want to go back to factory). I've got pics of my finalised setup somewhere at home I think. It doesn't look pretty, but it's internal so who cares!

The thing on the top of the pump is a spring ball bearing valve. It's designed to stop fuel flowing back into the tank when the engine is off, but since it was so hard for me to find a banjo fitting for it I decided to remove it and I haven't noticed any issues with starting, even when the car wasn't run for a couple of weeks. All it will do is restrict flow slightly so I don't think there's any reason to keep it on there.

I've been told that it's a good idea to upgrade the pump wiring for an 044 because of the extra current draw, but I kept the factory wiring just replacing the end terminals with round ones, and I haven't noticed the wires getting warm or anything. It might melt one day in the middle of summer but it's been going strong for over 2 years now, including very hot middles of summer.

Thanks heaps mate. I take it you have an R31?  Please send pics to [email protected]

What did you do about the filter mesh?

Argh, can't find the pics ;) And it's for an R33 not R31 sorry, but I imagine the setup would be similar. I'm really curious about the pics now, I mustn't have renamed them to something appropriate so they're lost on my hard drive. I'll go through all my pics when I have more time.

For the mesh, I cut off the one on the factory pump, and secured it to the bottom of the 044 with some fuel hose and clamps.

Cheers. gtrken says that they wont fit in a R31, but they will fit in a 32 33 etc. The fuel tank set-up must be different in an R31. I still reckon I can make it fit though. Did you have much trouble getting that non return fitting of the pump? Is seems bloody tight. The reason I want to take it off is because its makes the pump to long to fit in my bracket.

The non return fitting? You mean the ball bearing spring thing? I removed it primarily because I couldn't find a banjo fitting for it, but yeah it did add to the length and would have been somewhat harder to fit if it was in place. Oh yeah, I also had to completely remove the bottom of the bracket. I tried to bend it a bit to keep it in place as a spacer, but I gave up because it made the whole thing too wide to fit.

One thing I do remember quite well is the fact that it was very very difficult to push the bracket all the way down the slot even with the bracket chopped, to get the pump to reach all the way to the bottom of the tank. It's a common hassle with these pumps because they are wider than the factory pump. I had to bend the bracket kind of into a slight "S" shape to place the pump back out of the "corner" it's supposed to be in. I've actually found a photo of that view of the tank (attached), as I was trying to work out how to fit it exactly. It took several attempts but I finally got it.

I can't imagine the R31 being impossible, the R33 was hard enough as it was. Perseverance should pay off.

Yeah thanks. The R31 setup is totally different to that. I can make the pump fit in the bracket and then fit it back into the tank OK, the prob is that with the fittings on top of the pump the will be no room to join the fuel lines on. Its distance between the bottom and top of the tank that is to small.

What fitting did you end up using and where did you get it?

Now you're testing my memory. I think I just used a straight screw-on barb fittings, but I might have put some sort of adapter in because I think the 044 has a bigger outlet than the car's fuel line. I got almost all the parts from Earl's in Silverwater. I also went to Pirtek looking for the banjo fitting but they couldn't help (neither could Earl's).

The main reason why I don't remember specifically what I bought is because I spoke to the guy at Earl's and showed him the pump and sock and said how I needed it fitted, and he went and got all the parts he could and we fitted up what we could while I was there. I didn't have a "shopping list" as such.

Maybe you could make a sharper angle with the hose with a right-angle fitting so that you could mount the pump diagonally or horizontally to clear the space? I imagine this is much easier said than done though. Good luck with it.

I just done some looking around and I was mistaking about how the banjo fitting might hook up. Apparently the banjo fitting comes out at a 45 degree angle anyway (which would probably give me enough room to join the fuel line). So if I can find one I should probably be right. This is just a pic I found from a google immage search.

I take it that this is exaclty what my pump should look like with the proper banjo fitting?

Are the pictured pumps ready to be connected or does something else need to screw on above the banjo fitting? Just a nut to hold the banjo fitting down?

    • So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
    • When you pulled it off, there is no signs of blown head gasket? Is it possible you have some other issues going on? Possible cracked blocked? Or do you think it's straight up lifting the head? Did you check what the head was torqued to before pulling it down (To see if possibly they're stretching, or starting to break threads out etc)?
    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
