Quick fuel rail question

[caduceus]

Which way round do the pipes go on to the injector rail? I assume the fuel is regulated before it goes to the injectors (feed) and not as it leaves the rail (return)?

Thanks in advance

Other way round. Regulator on the return
Otherwise the fuel rail wouldn't have regulated pressure

I always take off one compression fitting and one tube and clip so there isn't any confusion.

That's great. Thanks Alan.

So just to confirm - like this:

yes

Now that's clearly understood, and as that picture is so helpfull, all owners including the ones who aren't mechanically minded should endeavour to check the two fuel (rubber) hoses that connect to those two points, check where it bends and turns back on themselves and before they go down and behind the engine, I need to check, mine could be two years old now, vpcant remember if they were changed last year as part of MBE upgrade, anyway they have small splits forming on those two bends
This is possibly the greatest risk to all our Tvr's survival, look closely.
I'll try taking a pic.

I like a good fuel rail, need to get a polished one

Also near impossible to get the rocker cover off if you leave the compression fitting on.

Is that a bit of rubber hose on the back of the regulator? Didn't realise there was any there when I renewed all of mine

I imagine he put that there to stop any crud getting in there before reinstalling it.

Yep about 3"

The rubber hose goes from the regulator to the inlet manifold. It is a vacuum hose if that's the one you're talking about .

There's a bit on the fuel side of the reg as well
