What problems would i have with my pyro pickup just outside of my turbo (exhaust side)???

 

The reading won't be as accurate and there will be a lag in response.

 

so im supposed to tap into the cast iron before the turbo? if so how??

 

just drill a hole and tap it, theres a pic of where in my gallery, it uses a 1/8 pipe thread tap.

 

ok ill give it a try tommorow when i get new tap, also is there a spot to screw in a fuel pressure gauge between the pumps?

 

To get a spot for fuel pressure, you need a tapped banjo bolt. Geno's garage has them, they are advertised as a 24v part, but fit 1st gen's too. Or you could get a new banjo bolt and tap it for 1/8 pipe while your doing the pyro. There isn't alot of meat to do this but mines holding up fine. I got one locally thats actually Detroit Diesel part.
