i thinking about taking off the smog pump ,but wonder if its going to mpg.
i'm getting about 16mpg ,but i hate having things on the engine that steal horse power away

calvin

Throw it as far as way as you can.it proubly is not working anymore anyways and just stealing hp like you said ....thow it man.

Ty

get rid of it.

See ya buy would be the last words to the pump as it went into the scrap pile. Just remember to plug the hoses leading to and from the pump. Large bolts and hose clamps work well.

ya i thought so, next on the chopping block is the egr valve, when i get time 2 put on the intake and new carb that is

NGM

There is a crossover tube onhte back of the heads. What I do is take that tube off and cut it about 2 inches from where it bolts on the head, then roll and lighlty braze the pipe and just bolt the ends back on. It blocks the exhaust ports that are on the back of the stock heads for the EGR.

Ty

what idoes that do any way?

NGM

Adds weight to the vehicle, breaks easy, creates exhaust leaks, gets in the way. Oh and its supposed to help the emissions in some way shape or form.

i know the egr valve on older trucks is not that important, but i would n't do it with a new one. i'm down to alt.,ps,and of course the fan belts. unless i get a electric fan (ya right water pumps still needs the belt)i have cut every thing out

NGM

Could get an electric water pump.. I don't know if they make a streetable one though. I delete EGR's on the new trucks/cars all the time. EGRs SUCK. Especially on a diesel.
