I'm considering running the whole fuel system using braided lines and AN fittings. Since I never had oportunity to use them I'd like to ask for help advice.

My main concern is connecting them to the carb or pressure regulator. Are this the type of fittings I should use: http://www.ebay.co.uk/itm/AN-4-Straight-FE...KQAAOSwh-1W3u96 Baring in mind different pipe diamateres of course. Second concern is my fuel pump has a plastic outlet will it be possible to seal it using same type of fittings? Any other suggestions what to use/avoid/remember about? Exactly what are you trying to achieve ? If you just retain nitrile rubber braided hose, then you can choose hose that will simply clamp over the way you've always done.. If you use teflon type hose, then for most part you'd be better adapting either the regulator etc to take proper fittings so everything screws together nicely. The fuel pump with plastic barb will probably never see a "nice" solution though if you wish to use teflon everywhere. But very easy to slap some rubber hose there. 9.85 @ 145mph

I'm looking for nice and tidy looking plumbing. Clamping over means that clamps are still visable and wires from braided hoses are usually sticking all over the place.

To do the pump properly...change the pump to one with a threaded outlet. 9.85 @ 145mph

Someone on here has done this before. As Stevie says, buy all the bits with the correct fitting.

I think Simon madmk1 has done it if you look through his build thread |

How much pressure can a fuel clip cope with? My build thread..

How much pressure can a fuel clip cope with? Depends what clip, what hose, how it's used, who installed it... But for a properly installed clip, suitable for the size of hose etc etc etc....I dont think any turbo/carb mini would ever be able to make enough boost to trouble it baring in mind some OEM cars still use such hose/clips on their fuel injected cars that may see 60, 70, 80psi pressure. So that'd mean a carb Mini would need to see around 85psi boost to match that. FPR should be easy enough to remove the brass fittings and tap out to 1/8NPT or 1/4NPT etc, whatever size is most appropriate. Carb same. But of course there is also the risk of damaging either components by doing this too and really for very little gain. 9.85 @ 145mph

But its high pressure for everything before the fpr? So the clips/fittings straight out of a mpi tank for instance are under whatever the pump puts out max psi up until the fpr My build thread..

I've done it in mine, mainly for a neater looking engine bay and ease of fitting/removal. Plus at the time I was able to get high quality hose very cheap. I'm aware there is no performance gain from this but once you've worked on engines with AN fuel hoses going back to fuel clips is so frustrating...

And whilst 1/8" NPT fittings are the obvious and easy choice for adapting the carb or FPR....ultimately these will be the smallest holes in the system and probably flow a lot less than the brass barbs that were in there before. Although probably still quite adequate as all will be a little larger than the needle valve in the carb. 9.85 @ 145mph

Neat look is my aim as well. Drilling out and taping will mean a lot of work hence the idea to use fittings design to work with hard lines. So cutting out the barb and flaring. But since I don't have the actual fitting in hand it is har to say if that is even possible. Made in Poland build thread:

I considered it but I think the hardline adapters look just as untidy as hose clips and the brass barbs are very soft. If you have access to a milling machine or even a drill press it's not difficult just takes time to ensure everything is square before drilling the barbs out.
