Hi,

I feel very stupid as heading states I hooked up fuel lines wrong way round. Just put my rb26 in my car and connected them up not thinking just so fuel didnt drip everywhere and to get them out of the way.

I hooked up wiring and fuel pump and starter, I just wanted to turn it over after rebuild, turned key to accessory and fuel pump started. meanwhile i could hear a strange pressure building noise and quickly switched it off.

very soon after i realised that fuel pressure had built and obviously couldnt get past the fuel reg and fuel passed through the injectors into the cylinders.

Q 1. are my injectors going to be okay after that sort of abuse.?

Q 2. is my fuel reg going to be okay?

Q 3. will this effect run in and the hone job on the bores or the rings themselves? (Fuel was pushed out of cylindars within half an hour.)

Q 4. Will I not know any of the above until I test each thing.

Thanks

Taylor.

I don't understand, I hooked mine up the wrong way as well once and fuel just didn't get past the reg, so how has it got into your cylinders ?

fuel shouldn't get past the reg the wrong way and pump should turn off once pressurized

I assume it pressurised the injectors so much they leaked out the tip. fuel got into the cylinders through the injector tip. fuel pump didnt switch off once pressurised it just kept pumping and filled the cylinders in seconds

on an rb26 the rails pressure reg is on the front of the rail itself before the injectors. the lines were reversed so the fuel went to all of the injectors first and stopped at the reg at the end and i assume couldnt get past the reg

Reg is definitely on return side cause it needs to regulate pressure in the rail..

so sounds like it is hooked up the right way..

So either your pump isn't switching itself off once pressurized, have your rewired it lately?

Or your injectors are stuck open for some reason..

maybe your injectors are getting voltage I dont know why this would happen

I had 90psi fuel pressure on mine and it wasn't enough to push injectors open, then again my pump would switch off..

Fuel can't get past the reg and even if it does you won't have much pressure in the rail because there is nothing to stop it running back to the tank.

The reg restricts flow back to the thank to increase pressure in the rail.

Your injectors, reg and engine will be fine.

If you're really scared and want to be sure pull the spark plugs out and crank the engine over with the cam angle sensor disconnected to clear out any fuel in the bores.

Id say more then getting the line's the wrong way you have leaking injector seals? Or the reg jammed shut over pressurising the rail causing fuel to leak past the injectors?

Everything would now have been washed of any oil on its surface. Id drain everything, leak everything open for a few days to let any fuel evaporate out then refill with oil, then crank it by hand for a while?

    • The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.
    • Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.
    • Since winter isn't that harsh anymore in Poland, i will definetely drive it 365 days a year 😉. But if the snow hits i will try it for sure and let U know. Only swap i am planning to do is of course R34 GTR front 😍.
    • Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
