This thread is going to have to be turned into a series soon! It's massive! I'v tried to read it all but i have to skim a lot as i don't have ages to read it all!!!
Awsome work though, keep it up!

Thanks for the comments both
Zeifer - yup, the weld are certainly holding up :thumb:
As solutions to the fuel? with an external fuel pump or with that of a nova GTE? I do not understand that.
The solution to the problem of fuel starvation, was to have a fuel swirl pot.
This if fed by the external low pressure, high voltage fuel pump (the FACET redtop)
From the swirl pot, I have a high pressure fuel pump from a Ford Sierra Cosworth, feeding the engine.
Hope this helps?
Just to add a bit more flesh (If I may)
The problem of fuel starvation occurs when the cornering speed of the car is fast enough to pull the fuel in the tank way form the outlet long enough for the fuel pump to start pumping air.
This results in the engine losing power for a few seconds as you exit the bend (usually). Not ideal!
So the solution is to have a swirl pot, which is simply a tiny external fuel tank. The swirl pot is fed by a low pressure pump from the main tank (it has a return). The engine takes its fuel from the swirl pot and returns any unused fuel to the swirl pot. So you have two fuel loops.
Since the swirl pot is tall and thin the fuel cannot slosh away from the feed. So when the main tank is pumping air you still have a head of fuel to feed the engine.
well said!
So, what is needed are two fuel pumps, a low pressure and high pressure, with a main tank and a secondary, sending fuel from the primary to secondary through the low-pressure pump and engine for the secondary amid the high-pressure, it is right? Well, as you say you use the fuel pump of the ford to high pressure and low? that of a GTE?
Could this be an issue in my turbo diesel nova?Quote:

Precisely mate :thumb: very common symtomn!
The supply pump doesnt need to be low pressure, you can use a high pressure pump if you have one lying around. The fuel wont actually get under pressure itself as there will be no fuel reg in the first circuit. So in theory, if you are converting a car that currently has a carb engine, you dont need to change the fuel lines for high pressure injection ones.Quote:

Some swirl pots (like mine) have only 3 nozzles, so the returns need joining in a t piece, but normally there are 4 nozzles.
