[Vwdiesel] I have an idle, but it dies on acceleration

[James Hansen]

I wouldn't bother with marvel.  If anything is going to unstuck the pump
vanes it would be LMDP.  To assist things when you start it again, you can
put an electric pump in line to boost if needed, but only if you have one
already, they are around a c-note.
