one for the experts ?

heres the problem i cant get fuel up to the fuel filter on my mk 1 cabrio 1.8 dx engine,if i remove the fuel pipes from the top of my tank i get fuel from the near side pumping out from the tank pipe when cranking but nothing gets to the filter? when i stop cranking a small amount of fuel comes out the return pipe ? anyone know what the problem is ?               

No expert. sorry but sure one will be along soon.

Have you checked the inside of the tank to make sure thats all clear and any filters not blocked, appreciate you are getting some fuel through low down but may be a buildup is reducing the flow.

Could try getting the lines blown out as well to make sure they are clean, or run a new temp piece of fuel line up to engine bay and check it pumps fuel through. Both connected to filter or running into a suitable container to check its can be pumped up that height.

check the main pump under the car is working

the pump is in the tank ?

Your car should have two pumps I believe. The one in the tank is just the lift pump. There should be another pump that is capable of supplying the fuel at high pressure to the distribution block in the bay.

yes there are 2 pumps, the main one under the car, and the one in the tank which just keeps the main pump supplied with fuel

Only happens when engine is warm

badboy777 you need to calm down mate!

right, can you please explain your problems properly and let us know what you have done so far and proper symptoms or its going to be hard for people to help you.

Posting/spamming a thread with a post every 2 mins is going to get you nowhere.

Sorry m8 i get a bit hot headed right i got a 2.0l short block
from a mk3 golf gti 8v tock my head of my 1.8 engine put it
on the 2.0l block so i can still us my kjet injection changed
the distripator with spacer ring and changed fly wheel and
clutch been running great but i tock it on a long jourmey
on the motorway doing about 70 to 100 and now still runs
fine but if i stamp down on the throttle its so flat if i press
the throttle slowly it ok and it only dose it when its warm
any clue m8

hmmmmmmmm I personally don't know what that could be, but someone will be along to tell you im sure.

Prehaps starting your own thread will attract some more people to look at your problem?

have you had the CO levels checked, aim for around 1.8%.  possibly a WUR fault though, but to find out for sure you need access to a k-jet fuel pressure testing kit.

might be an idea to upgrade the fuelling, fit a 16v fuel metering head plus wur, mount it upside down so you can get the vacuum pipe hooked up for throttle enrichment.  then with a fuel pressure testign kit you can play with the wur control pressure to up the fuellign a little bit.

mk2 gti throttle body also a good upgrade but that needs mods to the inlet manifold. unless you fit a MK2 8v GTI k-jet inlet manifold, but then you would also need to change the fuel lines and air box + piping for mk2 k-jet stuff so not an easy swap. prob not worth it tbh, just mod the mk1 inlet.  a MK2 G60 inlet might do the job though, possibly

Going to get the co levels look at now thanks a lot john
Ill let you no what i find

Hi john had the co checked it was way to low 850 turned
it up to 1.790 seems fine put just takes a pit of time to
fire up when cold and sounds like its missing and then
clears and then runs fine and if you turn it off and then
start it again it fire up fine fills like im getting there tho
cheers for you help m8

might be 5th injector playing up, gets power from black wire to the starter, and earths to the block via the big brown thermoswitch. tests all covered in the haynes anyway
