R33: Replacing Fuel Filter

[joemac]

Replacing the fuel filter on an R33

This is probably suck eggs for most people but just thought I’d post any work I did on the car as it may make things easier for others when going through the same process.

Things required:

1. Stubby philips head screwdriver.

2. I used a Ryco Z201 filter but yours might be different

3. Water

Steps involved:

1. Ensure the engine is cold as you will lose some fuel in this process

2. The engine manual states that you first need to reduce the fuel pressure (by removing a fuse). I skipped this part. I found that there was not much fuel loss or pressure anyway.

3. At first, I could not remove when trying to loosen the hoses from around the filter as I could not twist the hose to break the seal. I then set about undoing the clip and removing the hose from the bottom where it joint the metal pipe (see first pic). The hose slips off a lot easier here. You will need the stubby screwdriver to access this area. Once this was off I removed the filter from the bracket (only lost a little bit of fuel) and twisted the hose around so I had a lot more access (see second pic). I then proceeded to remove the hoses from around the filter by loosening then twisting the hoses off.

4. Placed the new filter on and fixed the hoses in place. Don’t overtighted as you don’t want to break the plastic from around the filter.

5. I then washed away any spilt fuel with some water

6. Started the engine and checked that there were no fuel leaks

hey man good write up..

how much was fuel filter, i assume from Repco compared to original Nissan if u know?

are RB20 and 25s the same, im guessing they are?

[joemac]

The fuel filter was about $25 but its probably different to the one you want. Just go into Autobahn or Repco and do a search through the parts catalogue to find the specific type.

Not sure what the price difference is to a genuine nissan filter. I plan to change mine about every 10,000k so the Ryco should be OK.

In one of my Z's i used to prime the fuel pump before the first start after this to cycle the fuel around and get rid of air let into the system.

Not sure if it is the same on the skyline or even necessary at all, but I do it.

You can also place a sheet of cloth in the area the fuel filter is to catch any petrol that spills.

The car did run a bit rough for the first minute after starting. How do you prime the fuel pump first?

[drunkenmaster]

Just turn the electrics on, you should hear the fuel pump whir as it pressurises the system, well, on the old cars anyways. Like i said, I am not sure about newer skylines etc.

This is just my logic as well, I have no confirmation or resources that tell/told me to do this

Maybe one of the mechanically trained members can shed some light?

the car runs rough for like half a minute after changing the fuel filter but it doesn't do any damage

joemac, the fuse for the fuel pump is located next to the battery.

& u would like to open the Fuel cap so fuel could flow back to minimize bleeding

I use Z32 filter as its less restriction. Will fit prefectly...just need force to enlarge the bracket a little & cut hose a little shorter ..size comparsion

If you have an immobiliser that cuts your fuel, you can use this.

Start the car with immobiliser on. When it dies there should not be much pressure in the fuel line.

or just start the car & remove the fuse & let the car to stall<<< But I tried this way....still bleeding alot..I open the fuel cap...bleed stopped

I'm stuffed if i can get any of those hoses to come off, even the alternative one mentioned further down.

Grrrrr!

Any ideas?

[wolverine]

suck shit. we have all suffered too.

sorry about that, being serious they are really tight, if all else fails you can cut the hose and if needed replace the hose if there isn't enough play left in the remaining hose.

i have done mine twice and second time around it wasn't much easier.

[Birnie]

Haha, noice !!

Thanks for the info

[wolverine]

did u get it done?? all fingers and tools intact...ie. no screwdrivers stuck in the ceiling etc.

Have also done this a couple of times.

I have memories of screwdrivers, leverage, a lot of cursing and a little blood (optional).

You'll get there.

[Birnie]

Nope, not done yet.

Two attempts with the cursing, a little bit of blood but nothing very serious.

I've heard maybe using a hairdryer to loosen it up?

An old wives tale or worth trying???

Might work. Just don't use a match to warm the hose up a little!
