Prins VSI Problems

Post by rizel23 » Wed Jul 20, 2011 5:51 pm

System is;

Prins VSI multipoint system with a Stako doughnut tank of 77 litres (installed professionally in 2005)

Car is:

MG ZT 190 V6 2.5

Car will try to switch over from Petrol to Gas, but does this;

then either switches back to petrol or stalls if not moving.

Gas comes from here;

would i be correct in thinking that the vaporiser/reducer has a hole in the diaphragm? Will a repair kit work?

I'm based in Warwickshire, many thanks!

Whilst i was there i took note of my filter;

LPG 67R-010096 CLASS 2

CNG110R - 000028

260 PIS

180/80022 (Bar Code 1)

do i have the older type that unscrews to pop new filters in?



If any could suggest or supply both parts please do let me know, i take it my vaporiser is the older versions?

Many thanks! Sam

Hi

Your vapouriser/reducer is the older version (D). Newer ones are F, G, H as far as I am aware.

Seems as if you need a vapouriser rebuild as long as it isn't too corroded internally - in which case, you will need a newer version.
