No matter, our Canadian friend has furnished the image - thanks for that :



As you can see, pretty much as i described it. Looking at it, i suspect you've either had a replacement pump at some point or someone has broken the coil-clip type bracket and/or screw in it and used an exhaust "U" bracket as an alternative method with the rubber as a precaution against crushing the pump and also to pack the pump diameter out to match the ID of the "U" clamp. The "U" clamp would have been chosen to match the pitch of the bobbins which also may have failed, perhaps due to a fuel leak way back in the mists of time.

The way i see it you have 3 choices, first live with it being a bit more vocal than you'd expect. Second is to measure the ID of the "U" clamp and the OD of the pump, get a piece of neoprene sheet whose thickness is half of the difference between the two sizes and fit that in place of the existing rubber or thirdly, find some bobbin resilient mounts suitable, the correct coil-clip type bracket and putit back as Mr Volvo intended.

My vote would be for the last one.

The U bolt would seem to be non-standard. It is fine for the time being - in the longer term I’ll find a proper bracket.

Sorry, been away for the weekend Alan, but to answer your question, NO, that is a fabricated method of securing the pump using an exhaust 'Banelli' clamp that someone has done.

There should be a circular steel band type bracket around the pump (a bit like an ignition coil bracket) and that is in turn mounted to the pump position plate with two rubber bobbins.

The rubber packer will be insufficient to damp out any pump vibration and noise.

Methinks you have some simple fabricating to do!

Nice to have almost the same words as i used said by someone who actually has experience of the model!

Great minds think alike Dave!

I suppose in the past even 'bodge' repairs had an air of slight professionalism about them and were done in a way that they would last, hence the robust Banelli exhaust clamp. Nowadays the job would most likely have been done with a couple of plastic 'Zip ties'!!

Without a doubt if Alan replicates the original fixing method, the reduction in noise & vibration will be noticeable.

As bodges go Paul it's one of the better ones i've seen! One of the worst was the spaceship bushes on my 760 packed out with an assortment of washers (not even the same washers both sides!) but only on the front of the tie rods, pushing the control arm backwards making it toe out like Charlie Chaplin!

Many thanks Paul and Dave,

I'm pleased we got to the root of this. I'm pretty sure the noisy fuel pump is as a result of the bodge - but as that may have been in place for 20 years there is no particular rush to fix it.

Now that I know what the solution looks like it should not be too difficult to fabricate something very similar and mount it on some Mini exhaust bobbins.

This little mini-thread again shows the value of this forum: as has happened with the RB thread many times, I have gone from a standing start to solving the problem in a day or so.

Just a thought Alan - do you happen to have a spare coil with its bracket attached floating around anywhere? Might save you a bit of fab time if so! Also :

Not the cheapest on fleabay but comes with two nuts (confirmed in the listing) and gives sizes in the listing too.

Hi Alan, the correct bobbins are available, second item down on this page.

https://classicvolvoparts.co.uk/part...Fuel_Injection

The correct mounting plate steel, is not too complicated. I don’t know if you have any Classic Volvo parts recyclers on your side on the pond, but if you do I would think they could provide one, as it’s not really a “wear” part, same for the clamp around the pump itself. Maybe Simon at Brookhouse can help with those.

Thinking that the current clamp you have, probably hasn’t done any favours to the pump itself. Possibly crimped and contributing to the noise.

Upon a review of the pictures, it appears you do have the mounting plate as original. (Possibly an opportunity for disassembly, cleaning up and a quick spray). So a proper clamp and bobbins will likely do the trick.

That is exactly what I was thinking Dave - I have a spare coil with its bracket in my spares box (like everyone does) - I had a look at it last eve and thought it might just fit (Delores isn't here at the mo).

There are any number of fuel pump brackets available on the internet, such as this one (just an example):

https://www.ebay.co.uk/itm/133138596...Cclp%3A2047675

I think it is just a case of measuring up with the callipers to find one that will fit.

I can feel a neat and tidy solution for almost no cost developing :-)
