VT problem on Petrol

[VSteve]

I have a duel fuel VT V6 and it has developed an issue when running on petrol. Basically it will struggle to run at anything above idle. It feels as if it is running out of petrol. I have an AFR gauge and this also reads very lean when trying to accelerate. Any ideas as what can be causing this issue?

1) A partially blocked fuel filter.

2) A dying fuel pump.

3) Partially locked injectors.

How long has it been on lpg for ? Lpg usually results in the degradation of your injectors from not being used enough and can have build up from the lpg on them. If you have dual fuel, clearly your only using petrol when you need to fill up gas ? I and alot of others have similar problems, my one just hesitates and is rough at high speeds. When i did my intake manifold i sprayed teh ends of them with carby cleaner and they worked well for a while, now starting to be sligthy rough.
