Smaller diesel engine, that would replace a gas inline four?

If the original truck was carburated or used throttle body injection, then you won't have to change out the in-tank pump. Pressure is fine for the IP. It's only the newer multi-port injection systems that use the high pressure pumps. Ran the Buick on the in-tank for about 2 years until it went to greener pastures. Replaced it with an in-line pump from NAPA for about 50 bucks. The new pump draws through the old pump fine. No need to even drop the tank. Kept the chassis fuel filter in place as added insurance, though it is a pain to replace, and used the older style box type diesel filter used in the earlier models of 6.2 trucks.

My truck is a fuel injected four cylinder right now.

Can I use that? it has an adjustable regulator.

Yes that regulator will work but I would check fuel rail pressure first. From your original picture, it looks like your truck is throttle body injected and as such would be using the low pressure pump. No need for the regulator.

It is throttle body injected, I forgot.

Would there be any problems running diesel through the existing fuel system?

No. But you'll need to install a return line to the tank.

I was just thinking about brakes with the diesel, and it was mentioned that id have to convert to a hydroboost configuration.
I'm pretty sure I saw something about a vaccum pump that would let you use the original brakes.

[DmaxMaverick]

You could use an electric vacuum pump designed for it. They are noisy, and don't last long.

So the best way to setup the brakes would be a hydroboost setup?
is there any other issues like this when converting from gas > diesel?
