Fuel Filter connector replacements identification?

[Juddder]

Happy Sunny Weekend everyone

In the fun world that is Cerbera land I now have to replace the fuel pipes that connect to the Fuel Filter, and while I'm at it I might as well do the one from the Fuel Pump to the bottom of the Fuel Filter too, so my question is can anyone identify what size the AN6 Banjo connector should be to fit to the FRAM G3831 Fuel Filter from the following photos?

If buba is on the forums then he used exactly the ones I want on his Fuel Filter / Fuel Pump pipe replacement here but missed out the part numbers, but luckily I have most of the other part numbers I need due to the excellent post from billybradshaw on his post here

Thanks you guys!

The good news is that it meant that I corrected the alt. part list with the correct FRAM part number so a positive win there

Also, anyone sourced a replacement bracket as I could do with doing that at the same time too?

My FRAM fuel filter (yes, I've just ordered a new one from Amazon @ £18 - happy days)

and just how are we meant to get into this gap to unbolt this one !?!?

Assuming the fram filter is the same as the standard you need M14 x 1.5 banjo fittings.

Many thanks - that would look like this might be be the right part then for the Fuel Filter then?

The filter out to body hard line hose coupling is a mare, I did it with help and the suspension and diff removed, still got scared the corrosion would result in a snapped hardline. Also note this fitting uses a compression olive to seal.

Don't you just love TVR engineering! OK - so I think strategy here will be lots of WD-40 around the holding nut, and then very very gently undoing it from the hard line to avoid fracturing it or causing any damage. Other thoughts I had were to cut the hose off and join new hose to a short part of the existing hose as the leaking problem is in the middle of the existing hose, but that might be more trouble than worth

Shanksy87 said:

To get the filter out you need to remove the bracket completely, the nuts behind the rear seats are not secured so you'll need help for this, unless you happen to have 10ft arms.

Mine seems to be mounted on the boot side of the read wheel arch rather than the back seats side as the rear of the car is to the right in my photos. Maybe they just put them where they fancied!

Also the mounting grommets will likely be shot, so get some new ones first, and stainless M5 bolts.

HTH

Yes will do and yes it does help hugely - many thanks!!

Is there any chance you could list the parts you have used for this and the other fuel pipe mods. I am interested in upgrading mine.

Jon

Absolutely

I have a few parts stilling arriving, but when I have them all here I will list them out, measure the lengths of fuel hose you need, and document the whole thing

Much easier than trawling various threads to piece it all together for next time / next Cerbera!

[Juddder]

So the sun has stopped play a little bit (hence I haven't managed to fit these this weekend as planned) however here's the complete shopping list of everything I bought

I have a few extra of some parts as I didn't want to get to the point where I was short

The bit I'm also debating is how to remove the 'olive' from the existing straight pipes as it appears to fit AN6 connectors to these, you need to remove the bump (the olive from the end) - I'm thinking one of those round pipe cutter tools would be the best way to do it, but would welcome any feedback

So here's the first hose made up - it's the one that goes from the rear passenger wheel arch body hard line, to the top of the fuel filter.

According to TVR Parts, there are two different lengths of this hose, but mine measured out as 24 inches so that's what I cut to

Also, because I can't actually reach all the way in to the inner of the car to disconnect the existing pipe, I have cut off the old pipe and will be (temporarily) using an AN to standard fuel hose adapter until I can get the car on a ramp at my local garage and replace that with a hard line pipe to AN hose connector properly







and here's a handy guide on how to cut the AN hose neatly

http://anfittingguide.com/install-braided-hose-fit...

BTW I'd also recommend everyone check their own fuel pipes in the back wheel arch - as you can see from the shots below mine had really perished, and not just where it had sprung a leak but the whole hose was disintegrating!





I also tried temporarily patching the fuel hose so that I could get the car to my local mechanics, but the fuel pressure is so high it literally blew the fuel hose patch tape to pieces (so don't buy Fuzion Self-Fusing Silione Tape as even though it's rated up to 8 Bar, the Cerb killed it in 10 seconds flat!)

Any updates on the fuel hoses as this is a hot topic at the moment and I would like to change mine

So I worked with my local garage to put my Cerbera onto their ramp and this gave us enough access to get to the hard line fuel connector in the rear wheel arch (that goes through the body and exits into the engine bay under the coolant reservoir tank)

The original fuel filter pipe connector was rusted on so rather than risk snapping or bending the hard line fuel pipe we used a SnapOn Blue Line tubing cutter (about the size of small cigarette lighter) which we could get around the hardline

This is normally used for cutting brake line pipes and as it is so small, and doesn't produce any swarf [which could potentially go into the engine via the fuel system], we could cut the original end of the connector off to leave clean pipe to connect the new connector to

This meant the new AN6 hard line connector could be easily connected to the pipe and tightened and the car is now working properly again

I am yet to replace the rubber fuel pipes in the engine bay as those had not deteriorated when we inspected them but in light of the recent Blue Cerbera blaze (which I guess prompted your status update question) is definitely next on the list before I use car long distance again

I will post up some pictures over the weekend...

So here's a picture of the replacement pipe connected

Because it was dark and a bit rainy tonight I didn't jack the car so you can't see the far side connection to the hard line, but you can imagine what it's like - it's basically like a hose clamp but in AN6 form and easily accessible from the bottom with a phillips screw driver to tighten





Also I recommend having one of these if you are worried about this kind of thing - totally fits out of the way and means you've got a fair chance of turning off the fuel pump and jumping out to open the bonnet before everything really causes problems...

Does the hard-line have a swaged end? If not and it's just straight pipe, that's not a safe way to connect to it as, despite the pretty red (dummy) surround, it's not a mechanically sound connection. There are 'olive' type fittings available for this purpose.

I will double check with the garage but I believe the olive was removed to allow the old fuel pipe connector to be removed so will potentially then need to be replaced (although both the mechanic and I tugged on the pipe incredibly hard to test it was connected firmly)

I have also already built the same fuel pipe but using AN6 connectors at either end which I believe should be fine as that is a designed hardline connector?
