When you put a fuel pressure regulator on do you need to change the injectors too. I have a '89 TA GTA with the L98 TPI. What brand do you guys think is the best?

 

No there is no need to change injectors. I used TPIS on my Iroc and TA

 

nope, i went with tpis as well; i am very happy with it....

 

I think Holley is the best.

 

I agree, I think the Holley unit is the best.

 

Buy the least expensive one you can find. They all work on the same principle. Why spend money for a name ,TPIS for example.

 

The holley comes with a new diaphram and spring and is really adjustable. Not a PITA!!!

 

definately the Holley, hands down. it comes with a replacement rubber gasket, and its adjustable by hand, no tools required!

 

the holley has also failed many times for fellow members.......as well as those i know personally.

the tpis may be more expensive, but how many people complain???

when it comes to fuel it's important, you should go with what you know works unless you don't have experience then i guess you have to rely on others...i'd do a search before choosing though. the worst thing is to have one fail or break.

 

I have never once seen or heard a complaint about the Holley AFPR??

 

Neither have I...actually one complaint from a guy that had clearance troubles with the plenum when he installed it...but otherwise nothing. How can a AFPR fail?!?

 

Oh they can as a matter of fact i had a holley on my TA and i had to replace it, and as it states in the first reply i used TPIs

 

One word = Aeromotive.

 

But my question is how does it fail? In what way did it stop working?
