A couple of months ago, I posted about a little more power was need for my stock truck. Well, with my luck, the pump leaked at my job site, so I found a shop that would take the truck and have it repaired. So, it cost me my left nut, 2900 bucks with a rebuilt pump, valve adjustment, and change the diff oil (it has 110,000 miles on it). I know I am getting rape a little, but it needed to be done. Like I said before, I know nothing about diesels. I ask the mechanic or owner to bump up the power a bit just so I can pass the snails on the Fwy. He agree to only add about 15-16hp. Other then that, it would burn or have engine problems. They have to recalibrate the stupid pump to stock spec. I was disappointed or ****** to spend that much, to say the least. He's got me by my *****. I figure that 180-200hp is not too much to ask for. I don't need a rocket ship, but a little drivable power or top end speed. It there any legal BS he has to obey by? No smog on these older trucks on CA. Its a 93, 2WD. I don't care about warranty and he knows it. Any thoughts? Last time I am going to this guy unless you guys tell me he's correct otherwise. I find it really difficult to find diesel shop that will work on our trucks. I call all over the places most are only interested in large delivery trucks or tractors. Please advise. I am in Los Angeles.

I think for a lot of shops it's the liability that keeps them from turning up trucks. It does not sound like you are one but there are people out there that will have their pump turned up, not have or watch or understand what their gauges are telling them, melt a piston or ? then go after the shop for repairs. The good news is that VE pump is easy to turn up even for a beginner. All the info is in the sticky. I would not touch the fuel screw until you have a pyro. One the best seat of the pants upgrades is to install a 3200 spring. Good luck

 

It is against federal law and probably state law to alter the factory settings on a fuel device. The clean air act (federal) is a large part of it, but there are many federal and state laws that prohibit altering the fueling system. Many of the mods done to there trucks are illegal, so it is reasonable for a business to refuse. They are more likely to be fined or otherwise punished. Lack of enforcement does not mean lack of law against it...Mark

 

Does changing the spring mean the pump has to be opened up again?

 

Ok, I understand now. If I owned the shop I would refuse also. Thanks.

 

There are shops that will sell you a pump and do modifications but it will void any warranty they would have given you with a calibrated pump.

I bought my injectors and all of the internal parts for my VE pump from ADP BECS in Whittier, CA.

The only time I have ever had to have a shop do work on any of my diesels except for transmission work was on my 6.2 and the best shop I had found was Diesel Tune in Downey, Ca. They were an authorized shop for Banks.

Jim,

They have to rebuild it to factory spec. If the shop were to do any turning for more power, no warranty and I am OK with that, still he refuse to do it claiming the engine will melt. Of course I can't debate that because I don't know about the subject. I was under the impression that it has something to do with smog regulations. I can't blame him for that. I wouldn't know what to do if the pump hit me in the face. I am actually afraid of tearing into it only because I don't understand how diesel pumps work. This is a shop in Costa Mesa, we are currently doing work in Laguana so it wasn't too far. Thanks for the recommendation. I need to learn how to install some gauges.

 

Some shops are authorized by the company that make directrix parts. A Bosch authorized repair facility will not turn them up and will detune a turned up pump as they are required to only turn out spec pumps. My local shop out a front seal in my old pump. I got it back in a nice box with my fuel pin and 3200 spring next to it along with a top cover gasket and a wink.

YouTube ve pump adjustments. Crossys Son has several step by step videos on how to do it and he explains very well what you're going to be doing.

 

Yes but just the top. Details are in the sticky. If you are not comfortable doing it I think a shop would do it for you it just allows the pump to fuel to a higher rpm it's not adding to the amount of fuel the pump is putting out.

 

Oh, thanks. Now I understand.

 

I think the biggest thing is.. do you trust your work after the pump was upgraded. It can get very complicated

If you do trust your work, have at it! Doing rollers is a pain, lots of P-jelly

 

I have no idea what rollers are? Can you please point me to the right direction? I have viewed one of the utube videos. One would think I should be able to do this. I can build you a custom home on a cliff overlooking the ocean, I should learn how to do this, but I am stumped. Got lots to learn. Thanks. Now you see why I can't trust myself, because I don't even know the basics.
