Do you still have Hicas?? If not, the two hardlines that run under the car are perfect for weld on fittings and some dash 8 hose, in my application we use 2 044 pumps via a 4l surge tank to a twin entry fuel rail, sard fuel reg and 1 std line for return.

i have the hicas lock kit on my garage floor but what would i need weld on fittings for?? i thought it was just a surgey and two pumps in the boot running lines under the car to the twin entry rail.

Yes that works, mines like that.

If you do a search on this topic youll see threads with all kinds of into and pics etc

best thing to do for that number IMO is to have 2 x 044 s running from a surge tank with stock pump as a feed. Do a new return line to the surge tank, twin entry rail, easy as

Yes...mines also like that....good for 1000hp at the flywheel.

I use the stock feed and return as feeds and a -6 braided line as a return. 3 Bosch motorsport pumps (one gauze bottomed swimmer pump in tank and two 044's off the surge tank), 1000cc Blitz injectors, GReddy twin entry fuel rail and a Sard regulator.

Works well :P

i didn't use the hicas lines for fuel lines instead

2 stainless lines feed and 1 return from gas tank all the way to the front

3 HKS 280L fuel pumps (intank)

2 inside the SARD 1L fuel tank and 1 in OEM fuel tank

aeromotive FRP

Tomei fuel rail

1000CC injectors

that is a flash setup, very nice with the gold fittings, gives it that japanese feel about it - nice gtr btw :P

yeah the sard surge tanks are good. they are basically like a mini fuel tank with inspection port on the top and you can mount your 'external' pumps inside it which does quieten them down a little and keeps them relatively cool too as they are sitting in fuel. it's a good way to go.

On the topic of fuel pumps, whats the max an 044 can handle?

I've set up my 044 intank pickup on my BNR34, looking to push around 380-400awkw on 2530s.

DiRTgarage, from memory you're making around 402awkw on 98 with 2530?

Any suggestions? Wasn't a lot of details on the article from HPi the GT-R special... haha!

a single 044 can handle the above quoted power BUT you need to take into consideration the integrity of that setup i.e. what if u get fuel surge which u are gauranteed with that sort of power & assoc. g-force?

what if that pumps fails for any unknown reason, the only warning you might get is 'pop'

also, running 400awkw the engine becomes much more reliant on fuel delivery

in other words, i think u would be mad to run a single fuel pump as many others would agree - walking on egg shells

With regards to fuel surge, i always keep the tank pretty full. Usually pour when there is about a 1/4 of a tank left. However, i guess i could always keep it above half in worse case scenerio?

If the pump fails, wouldnt the engine just turn off? I recall driving and the hose to my surge tank came lose, i couldnt accelerate no more and the car just gradually turned off? So what kind of pop are you talking about?

I've got 800cc sard injectors, sard fuel rail and sard FPR and its dual entry so i suppose i have done the fuel system oks, however, i used to have a sard surge tank though i had petrol smell in my car, is that common when using surge tanks? I found it quite wierd and couldnt take the air pollution inside the cabin!!!

i thought u would respond with "i'll keep the tank full" as i has similaar thoughts but then bit the bullet & ran a proper system

more than likely engine will just turn off but if you're pushing that much power you dont want to run lean at all - pop as in engine failure

i know what u mean about petrol smell in the car - ive had that before & apparently it boils down to the type of fuel hose as some are porous? correct me if im wrong but this is what i was told

      Harness update time have had great fun and learnt so much already so far with this project. I started off making both the ignition and injector sub harnesses in the hope any mistakes i made here aren't as hard to undo and learn from as the main harness.  A cool comparison of the old harness using presumably TXL wire and the new which is using Tezel. Also opted to use DTM plugs to keep the whole setup as neat and tidy as possible and tucked the wiring under the coil bracket to try and keep it all from sticking out too much. Although the injector harness, I'm not overly happy with as I'm still using the rubber boots that are supplied with the type of plugs it just looks ugly and sticks out like a sore thumb with the white identifiers so a slight redesign may be done.   Then it was main harness time and most importantly trying to route it nice and away from the heat it will use the OEM heater hose routing which is no longer present to keep the harness up high and secure. it's amazing how much smaller this harness is able to be compared to the old one. plugged everything into the emtron and with the help of the tuner again attempted to start it up and instantly fired up and running smoothly on all 6 which was a big shock to myself. So still some routing and adjusting to be done for the final fit up and installing a knock sensor harness plug which is in the post all has gone surprisingly well.     The old harness for shits and giggles.

      They do that at random every now and then, with almost no detectable cause. Mine has done it a couple of times (over 25 years!!). Never worked out why.

      I don't post on here and have been lurking for some time now. Many of the topics have helped me out more times than i can count. I was racing yesterday (11/9) and blew a front right CV shaft. I have spares so I popped a new one in. A thread i read previously said to check the engine mounts if you blow a front CV. Upon inspection, the front right mount was completely separated from the upper plate. This discovery saved me time and money, because i would have blown another CV if i went back out. Just wanted to thank you guys and wish everyone luck with with their builds. (Now if we could only come up with a solution for my power steering belt flying off after hitting the rev limiter, lol)
