I am going to replace the standard Volvo (CAV type) fuel filter with a Racnor spin on type. Question is what are the original couplings connected to the fuel pipes? Normally they would be a compression fitting but look more like a fixed fitting. Anybody had these fittings disonnected?

That is a very good point. I asked VP what the fittings on my B47 pre-filter were, they replied: "The 4 entries/exits on top refer to ¼? ? 18 NTPF. The one on top (next to the centre) refers to M10 X 1,5 "
I?m a bit confused by pipe thread terminology. I think this is a ¼? ID pipe, 18 TPI, actual pipe OD 0.546?
I want to replace mine with one with a glass bowl, but I'm not paying VP prices!

Thanks for the info. What I do not understand is how the connection is made up? The crimpted end of the fuel pipe looks as if it is one piece not a compression joint. I want to sort this out before disconnecting from the filter.

At the start of this year I had fuel problems and needed to remove the filter head pipes to clean it out. From memory the fuel pipe fitting at the filter head were swaged into the fuel lines and I needed to break the fuel lines further back at the fuel tank/lift pump/leak off rail to allow rotation of the pipes at the filter head.
I hope that makes sense!

Speak to in-line filters, they may have a bowl with a shorter bolt that fits your body http://www.inlinefilters.co.uk/index.php?main_page=index&cPath=918_921_940 (http://www.inlinefilters.co.uk/index.php?main_page=index&cPath=918_921_940)

Hunros,
Your answer is how I suspected that the pipes will not rotate without a free end (strange arrangement) I presume once released from the engine end I will have to remove the filter head and rotate it? My previous filter's have had compression fittings.

From memory, I'm pretty sure that the crimped fittings have a part that rotates. I certainly didn't have to rotate any fittings.

Just did mine. I had them crimped at a hydraulic machinery factory.

I have also done the folowing modifications. The filter will save your fuel cock being blocked with any debris whilst the primer makes it easy to bleed the system in case of air ingestion.
