External Fuel Filter Mod

[Twotter]

Going on from my thread about DIY respray...

...Well the tank situation has gone 'pete tong', courtesy of TNT couriers, but the fuel filter mod is still on the cards.

I've bought some fuel hose clips (Hose Clamp 13mm re-useable | COA60928) and a metre of Motorworks finest fuel hose (Fuel pipe high pressure (1 metre) | TAA37827) - see Motorworks

Does anyone know if there are any other bits and pieces required ???

You'll need a Steptoe

Some way of attaching the fuel filter somewhere good - a nice rubber-lined p-clip? If you don't have ABS then you can mount it there up front of the battery.

A new fuel filter?

 

[Twotter]

Okay I asked for that

The bits I've listed are for inside the tank to replace the current setup where the fuel filter normally goes. Having read Steptoe's thread I'm expecting to cut a length of the fuel hose and clip it into place. As for the external fuel filter I'm intending to cut the fuel line below the QR and clip the filter in line. I haven't decided exactly where I'm going to mount it but a p-clip on the air intake tube looks like the best option.

Just make sure the fuel line on the tank is Ok to be IMMERSED in fuel. Most fuel line isn't.

I use BMW K series inside the tank fuel line.

Also regularly check the outside fuel line that you use to connect the filter. For some reason I've found that it cracks/perishes very quickly, and i've tried several different types.

Is it feasible to use a suitable length of 8mm copper pipe in place of the internal filter?.It looks like it should fit into the existing hoses and there wont be any problems with the "wrong type of fuel hose".

Vibration and copper don't mix!

But it could be worth a try if ya could secure it some way??

I was thinking of converting to a car type set up like a 1400 16v astra pump and filter but I'm having a problem tracking down their operating pressure so I don't overstress the relief valve

isn't the change interval 24K? gotta do a lot of miles to make having all that ugly plumbing on the outside worthwhile. i did it and took it off.

just my 2p.

Ditto - I'll be putting mine back to standard next time i have to go inside my tank.

The copper pipe would be the same lengh as the fuel filter;whats that,120mm, and clamped in the same way to the existing rubbber(or whatever) pipes.I very much doubt if vibration would be a problem.
Like the idea of a cheap replacement for the fuel pump.Would it sit in the tank or outside?.
I think most injection systems work at around 40psi,but can you really overstress a relief valve.They open when the system gets to the required pressure and return the surplus fuel back to the tank.
I wouldn't have thought the fuel volume requirements for a car are that buch higher than a one litre plus bike.Keep us updated with your progress on that project.

When my shoulder injury allows I'll be doing the 60k service and the fuel filter needs replacing. Since I snapped one of the six fuel pump mounting plate lugs last time I don't want to risk snapping any more. So I'm going to do the external fuel filter mod.

I've checked with Motorworks and they've told me that the fuel hose I've bought from them is fine for use in the tank so that's good to go.

On the mileage front I've no plans (or budget) to change the bike so my intention is to run it past 100k and keep on going as far as I can. That being the case moving the filter makes sense.

You need UV treated rubber hose. It's more plastic like then rubber.
