hi guys i know a few of us like to use 8mm fuel lines but what do you guys do with the regulator i believe its 6mm from regulator to the carb do you just use 6mm for this bit or do you mod the regulator, if so how?*tongue*

Done now needs redoing lol

All I done was put an in-line fuel filter between regulator and carb, which has stepped spiggots 6-8mm, in theory if I'm clever there should be a pic below. If not then I am a true tit.

Low boosting for now.

doing this is ok but would be no good to me as the outlet of my regulator is only 6mm and so is the carb fuel in. I gues you guys drill and tap them. Just thought it would defeat the point of having an 8mm surply to the regulator if its then stepped down to 6mm

That filter is no good for a high pressure fuel system like a turboed mini.

Just use 6mm from the reg to the carb.

I'm pretty sure that the reg has 8mn fittings. If this is the case, just use a reducer.

I'm sure the regulators have pretty big fittings, mine I can only just squeeze 8mm over, the carb is a little smaller, I have a fuel pressure gauge, oe side has an 8mm fitting, other 6mm.

as above my regulator has an 8mm feed from tank and and 8mm return but the surply to the carb and to the plenum are only 6mm. It looks like a standard metro turbo one. Well if its not going to make much difference il just use 6 from reg to carb il have to order some

They are plastic and under a lot of pressure. Doubt they will last long. Look at the oem ones, all metal bodied...

Indeed, the plastic ones are not designed to be used in pressurised environments.

You must swap it for an injection rated filter ASAP!

So I take it you can tell how solid these are just by a picture? Not arguing or anything but but ive been using it for like 2-3 months and my dads certain these a perfectly safe to use as his work supplies them, if they weren't he wouldn't let me drive it, believe me. So when it breaks or whatever you say, I'll understand

It's what happens when it fails. I wouldn't want to risk my car going up in flames...

I suppose it will depend on what boost your running, I would not like much fuel pressure in one of them.

Why do you think they specifically say on the various types of filters whether they are rated for high pressure, or low pressure?

The plastic/paper type filter pictures above may well be able to cope with high pressure for an undeterminable amount of time, and that's wonderful if you like rolling dice and gambling with stuff like highly flammable fuels such as petrol, because sooner or later, that filter is going to split or crack and produce unpleasent results in 99% of cases when they do break.

So, take a step back and think about it: Either pay a little more for a correctly rated fuel filter which is made to cope with the pressure it deals with day in, day out. Or, use a filter which is not rated for those levels of fuel pressure and sit with baited breath each time you drive your car, for the sake of a few quid.

I know which route I would pick.

Well I don't have any others to hand but we've got a few diesel filters at hand which are stronger so I'll swap to that for now until I can get hold of a decent one? Maybe they will have one I can pick up at MITP?
