i have a 98. 5 24v. my injection pump is on it's last legs with codes and running issues. so i'm getting everything geared up to replace it. i am curious if i should just get it rebuilt or if there are upgrades or aftermarket ones anyone has used that would be better. any information would be great. i have beefed up everything around the engine. bd transmission and things like that. im ready to start adding more power. i don't wanna race my truck. i just pull alot of heavy loads. so any info would be great. thanks everyone.
