You will need the spring as that is what stops the hose collapsing from the suction of the water pump when the system is cold and not pressurised , if nissan state a delivery of over 3 weeks chances are it is not made any more.

Why can't you use the spring out of your split pipe & swap it into the samco hose?
Thats what I done on mine this weekend, presume that's the done thing?
Amber performance was a 4 week wait as well but beat nissans 6 week wait & you don't want to be doing them again so I would vote samco's.
Bit of a pig to reach when in the car.
Are you going to block off the water feeds to the inlet manifold while your doing it?

Skyline iirc?

Remind me me and I will get you the part number , I use them as well.

I used the old spring in my samco hose, as long as its not corroded or falling to pieces it'll be fine.

Ah a sigh of relief with the samco's & the spring then as mine seemed fine.

Stugtir300 the reason I want to block the water feeds off to the inlet manifold is just to make it a bit more serviceable once fitted in the car.
I had to do a few jobs in that area with the inlet in situ before which I found pretty awkward with the inlet manifold fitted, things like the DET sensor, water pipes your having problems with.
Would be interested to know how many other members have done this and if there are any possible drawbacks bar it taking a bit longer to get up to temp?

I did read a thread about removing the cold start valve & associated pipework before but not sure if you need to be on nistune etc to get a decent idle.

Does anyone run with no water pipes to the inlet & no cold start on a stock ecu & if so do you have any problems?

Sorry to of high-jacked your thread but im in the same boat with the water pipes & thought it might of been some relevance to you with my other questions

I've been runnining with the water pipes blocked off for a couple of years and not noticed any difference, running standard ECU. Idles at approx 900 rpm.

i have also extended the wires underneath so I can lift the plenum off without unplugging them, only takes about 10 mins to remove the plenum then.

I have had the water pipes blocked off for the inlet manifold and never had an issue. Have also removed the water to oil cooler also as i run an external oil cooler. And have the sandwich plate mounted to where the old water/oil cooler used to be.

Think I just bypassed my inlet water pipes and used the original spring in the samco hose.

The larger filter to use is 15208-71J00, there was a thread on here aaaaaages ago where i worked out the areas of each filter, anyway here's a pic of the two filters...



and here is a pic of what Jim was talking about...
