Title: Pressure regulator clip
Post by: Snapey on Sunday, 13 August 2017, 05:58 PM
My 14 let me down yesterday for the first time in almost 200,000kms. It wouldn't rev then just stopped. Blocked fuel filter I hoped but on inspection it was OK (external filter). All put together again I tried starting it while waiting for Irish to return with a trailer. Bloody thing ran perfectly. I thought it was probably water in the system so after a good test ride I thanked Irish for his help & headed home. About 80kms later it stopped again so after the same flush procedure it started & I got home.

On inspection this morning I found the fuel pressure regulator clip was missing & the regulator was almost out of it's port so I think luck was on my side being able to get home.

So the point of this little rant is a reminder that next time you have the tank off is to cable tie the clip to the body because fixing it on the side of the road would be near impossible without the right tools.

The one inside the tank with the white plastic clip? I've had that fall off twice over the years.

sorry for the perhaps stupid question - but where is the clip?  :bugga:

It's the part at the top right of the picture. Just near the number 2. They only clip on & are prone to coming off.
BTW, take note of the prices in AU$

Yep, has happened to me also

There have been a few instances in the past whereby the clip holding the fuel pump assembly together breaks or comes (springs) off inside the tank so disabling the pump from working – hence your 14 won't start (last thing you want miles from home or on a wet windy night). So this tip/fix is more preventative maintenance to help support the clip and stop it from breaking / springing off in the first instance.

The original fix for this was to use an electrical tie to hold the pump assembly in place, and whilst this is good for a "get you home" fix, over time petrol can affect some of the plastic electrical ties available on the market so causing the pump to fail again!

See Note 6 under "A few notes and tips" in the following article http://gsx1400owners.org/forum/index.php?topic=430.0

A better solution determined subsequently is to wrap stainless wire around the pump to provide extra support to the clip to prevent it snapping or springing off. The pictures below (courtesy of Speedy1959) show the original pump and then how the wire is attached.

thinking a stainless steel hose clamp rather than wire. any idea what size in mm i need. i know lazy, should get it out, measure myself. help appreciated. just easier than out, measure, go and get, then refit. i have a huge selection at work.

I was using zip ties, because I had them on a road. But even using them I face an issue when it's hard to insert fuel pump unit back to fuel tank, because zip tie make it's wider. Have to place zip tie lock right, so it not disturb inserting pump in to the hole.

SS clamp (if I understand right, what you mean) may be to bulky, so you could be not able to fit pump unit back.

Where is problem with this issue? Plastic clamp broke?

Look at it more as preventative maintenance V_i_c_i  - the clip on the regulator can break - and has done recently - on a number of members machines, causing the bike to not start - often a few miles away from home. By adding the cable tie (or a similar clamp) it prevents that happening and you breaking down.

not broken but get loose over time. And just not able to hold preasure regulator in place.
Take look on a picture - white plastic clamp is complacently in place, but it's not tightly against filter housing, where is a hook. And because of this, fuel regulator felt out of its place.

Just to add to this.
I have approched the servicability of the fuel filter diffrently and thought you guys would be interested to see what the original fuel filter looks like on the inside.

Hi Grog it has been a very long time.
Between my wife and the new business I lost track of time, done less than 600k in 3 years on my 14 but she has had 5 oil changes 😂 I decided to look over her properly and start riding again now that the business is doing well.
Found she had fueling issues at high load and high rpm, found she was leaning out and I decided to sort it and renewed the fuel pump and done the same filter mod like you but it still is in tank.

Gidday Bielie, I recall the name, but not seen a pic before.  Was it you who had a PCV & autotune fitted?  I recall someone from Aussie had it.

stupid question - if I invert the tank, will it leak fuel out?

When I cleaned my "Teabag" filter and did the regulator wire clip mod I just ran my tank low (2 bars I think), then stood it upright on a rug.
Mine DID leak when I initially turned the tank upside down..
Its just as easy to remove the pump using my method..

The few times I've had my tank off, it's not leaked. Once it was nearly full too & I always put it upside down to work on it, not leave it at right angles.  Just lucky I guess.
Title: Re: Pressure regulator clip
Post by: northern on Wednesday, 18 July 2018, 07:23 PM
My personal experience: 2-3 bars on fuel gauge, tank is upside down and no leaking.
Tested this Saturday :)

usually plan to not much left, both flashing. have a suction thingo , designed to suck oil out of briggs n stratton mowers, to change oil. i use it to suck out last of fuel. then just upside down on a towell. never had a fuel spill. im very paranoid about fuel stuffing the paint on tank. have never looked at any other way. just how i do it.

Hi Kiwi
Yes got the PCV and Autotune, bike is at the dyno at the moment, I also fitted a cordona quick shifter.....now that is fun, seamless torque and acceleration 😂

I used a metal cable tie (medium) from halfords as in pic- they're 200mm and are just big enough.

What comes to emptying the tank, I detach the fuel line and direct that to a can, turn the ignition on and ump the fuel pump relay - it'll run the tank empty...

I had a problem with this infamous clip letting go while i was out on Saturday.
I'd ridden from Wakefield down to Grantham and all was ok.
On the way back the bike started misfiring and eventually stopped.
When trying to start it i could get it to fire but not run.

By this time i was stranded at the side of the A1 and it was 30 degrees hot and sunny.
Even tho i seemed to have plenty of fuel (three blocks) i walked to the nearsst petrol station and got a gallon.
No improvement.
I rang for a recovery truck and was informed that i was a hi priority case and a vehicle would be with me in 2 and a half hours.
Bearing this long wait in mind i pulled the tank off wondering if the tea bag was blocked.
When i went to withdraw the pump the white clip had come off and the regulater was hanging out of the pump body.
After i'd got the pump out i was able to push the regulator back in but with no white clip and no cable ties with me i was struggling to find a way to retain it.
I found a piece of blue rope at the side of the road and seperated some strands off it and tied the regulator in place.
This worked and i got home ok.
Yesterday i took the pump out again,drained the tank and found the clip.
Put it all back together and wound some welding wire around it too........
It'll not be coming off again.
This clip is just a poor design.
As some of you may recall i'd had the pump ass out to replace the pump a few months ago and i recall i did fit the clip correctly.....

I think it's the sort of plastic that get's weakened easily when taken off/put on again. Oh well, the wire does the trick!

I suspect the clip is a one shot deal, once it's been opened it does not close up properly to remain effective.  My pump was fine until I cleaned out the filter and replaced (correctly) it due to poor running and I had tried most other things and within a couple of months mine fell off as well, (3.5 hours wait for recovery) it's wired on now so wont fail again.
