fuel regulator leak causing running problems?
I've been having running problems for a while now mainly when accelerating. It's been very juddery and spluttery sometimes when
accelerating. I went out for a short trip round the village this morning and all seemed ok, its been intermittent so nothing strange there. I have
thought maybe fuel pump can't cope, veal getting into the mix, air restriction, even the timing being out? But the I noticed fuel dripping from
the regulator in the engine bay. It drips during idle and with just the ignition on (fuel pump on) could this be a factor, when accelerating air is
being sucked in rather than fuel coming out? I believe that its leaking from the "lid" of the regulator rather than the pipes etc.
It's now back in the garage as I don't fancy driving with fuel dripping into a nice hot engine bay.
The oil catch tank is getting quite full too but can't see this being a problem unless it stops breathing all together?
Any ideas?
Thanks and merry Christmas and a happy new year.

Bike pump or the low presure pump webcon sell. Huco is the brand name. I had one on my webers and now use it as a lift pump for my efi.
Some people have had problems with regulators as they can strangle flow rate.
You wouldnt need one with a a huco or bike pump.

Fuel leaking from the regulator lid seal, could also have an air leak to the pressure compensating diaphragm.
Fix that first
Don't chase any other perceived problem until the regulator functions properly.

Even if it isn't the cause of your problem, fix the leak now. Loose petrol in the engine bay is never the start of a happy journey.

Ok am going to remove it to check it out, how much fuel is gonna go every where when I do this and is this as simple job as I anticipate?

Provided the pump isn't running, there won't be that much fuel to escape. Whenever I've done it, I've just stuffed a load of
kitchen roll around it and in any nearby places that it's likely to pool.
