Hi, I'm about to put the walbro pump in my 99 ls1 TA. I was wondering after i put the pump in,Is their anything else i have to do? Like the pressure regulator on the pump side and also the regulator on the fuel rail side? I'm also putting a 36lb injectors. Would these 2 parts swap affect the presure? Please help and any info would be very greatfull.

 

if your tank is still in the car....a easy way to change out the pumps is to cut through the sheet metal right in front of your trunk hole....the fuel pump actually sits right in that area.....36lbs youll need to program into the computer with efi live or something...

 

Search around, because there are a few write ups on the proper way to cut through the car. It went pretty easy for me. I heard that GM would actually make a trap door for some camaro's if specified.

 

Where is the trunk hole located?

 

Do a search it is all over the place. Use the words trap door.
