Hi All

im having issues at the moment with a Dodge autosleeper 1981
First issue was after i had fitted a new(brand new) fuel tank i ended up with a tank half full of water and half full of fuel,
next the fuel pump ceased and no fuel was being pumped through,
i then drained the fuel tank fitted an electric fuel pump (Facet posi-flow 12v)
inertia cut of switch and a Syntec fuel regulator 1 to 5 PSI
changed the spark plugs cleaned the carb and sat back.

Now the van starts but only if i cover the top of the carb and it sounds lumpy
i have had the regulator set a different pressures but it will only run when sat at 1 1/2 PSI

Help please running out of things to try

thanks
 
Thanks Jim

will check just a bit off a head scrtatcher when you have replaced every thing
is she ran fine before i changed the fuel tank
 
The normal running pressure should be about 1 1/2 to 2 psi so you're in the right ball park with that. Blocking off the carb inlet you are effectively applying the choke so it sounds like it's running very lean as Jim has suggested in his post. Are you running the original Zennith? if so maybe there is a blockage - try building the revs up fairly high then slap the palm of your hand over the carb inlet, this usually sucks any blockages through and has worked well for a few people.
 
Water in the fuel tank is a problem on the spacevan. The filler neck is very close to the body and rainwater runs into the filler.
 
Thanks all im working away this week but will be straight on it saturday
i will let you know the outcome
and yes Panky its the original Zenith
is it worth changing for a Webber?
