well i'm doing the swap from tpi to carb and i have everything for the swap but i think some where i messed up i got a single in and out fuel pres regulator is it useable .it the only thing i can afford.if so how whould i hook it up.

 

Welcome aboard.

Look what I said in this one (the needle valve thing).

So it is not possible to use it well how whold i run a pump out side of the tank then because i don't have the money for the intank now.is it as simple ans hooking it up to the biger line that the fuel come from the tank.One more ? would it work with the fuel line that come from the tank,hooking it up to the regultor but before it hit the regulator it gos off to the return line.

 

Okay, I'll be a little more clear. . .

You can do it if you have a restriction in the return. The way I've seen one guy do it is to have a needle valve in the return so that the pressure is maintained under maximum demand. When demand is low, the regulator keeps the pressure to the carb down with partial dead-heading.

The down-side to this system is you don't have full flow through the pump at all times. However, it may (or may not) be enough to keep the in-tank pump cooled - that I can't say with certainty.

 

whats dead heading does that mean burning up the pump

 

"Deadheading" means controlling pressure by restricting flow. For instance, if the outlet pressure reaches the pre-set 6 psi, and there was no demand (engine not running, for example), then there would be no flow through the regulator. For in-tank electric pumps, this is not good because they will be developing their maximum pressure but no flow would be occurring. Since they rely on flow to cool the pump motor, it will burn out.

Some aftermarket electric pumps are okay with being deadheaded. You just need to know what your pump was designed for.

 

how about using the tpi adjustable pressure reg would that work

 

Hell no, an adjustable TPI regulator won't let you get below maybe 35 psi at idle. Not a chance.

 

i have a holly it is a double pumper what i after the rear bowl i just had it return to the pump return line that should work.

 

i mean it has duel feed float bowls.

 

That's one way to do it. The return will have to have a restriction in it in order for there to be any pressure at the carb. Such as a needle valve. . .
