Changing EFI Fuel Injectors

[Bezzer]

Here's the latest : A good mechanic I know said to call - Premco in Lampasas, Texas
www.dieselparts.com
Family owned and been in business for 50 yr. Sounds like a possibility. Probably drive there and visit the shop...and get a feel for things.
Don't know if any of you know them or used them for fuel injector service?

I've heard of them but don't know how they are with their work.

Update Fellows: After speaking to the Bosch Dealer close to home-Premco in Lampasas, Texas....(www.dieselparts.com )... He was more interested in selling me new injectors and then would charge me another $120.00 to check the flow rate.......nice person - sounded like a good place - but I lost interest in this place...so that shop is out.

April 26 a man (who had the same motorhome as mine ) told me about a shop that he used and was very pleased with their work.

I called them and they had rebuilt ones in stock to send out right away. Then I asked Mark if they would rebuild my injectors and they said no problem. I also asked about the flow rate and Mark said it would be within 2% of the correct Bosch spec's. It would take about a week and a half. I sent them the injectors yesterday.


Will get back to you later!

Bosch’s spec is like measuring with a yard stick and we are saying within 25psi lowest to highest which is like using a 1” range.

Stock Bosch, stanndyne, etc. are all to the GM spec. Which is + or - 250 psi.
So if the spec says 2,250, you can have some at 2,000 and some at 2,500. Will it run? Yup. And some people have 15% more power and 20% more mpg than others and wonder why. Because even “in spec” the cylinders are fighting each other. Think of riding a bicycle and having one leg in shape while the other has a twisted ankle and sore muscles. Now go race it or try pedaling up a hill.

Pay the money and if you don’t know the shop, pay extra to see video to see it or watch in person. Imo.

Balanced set to a specific pop pressure is the way to go. Just make opinion

Thanks Will L. and everyone that helped with this project----
Will L- Here is the new flow rate....opening pressure 2175 with 2% spread max.
I received my injectors back from Oregon Fuel Injection and installed them, bled the system, engine started right up with no pop from the tail pipe and no pop from the turbo side at the passenger seat.

We took a 50 miles ride and all ran great as usual.

The problem was starting in the morning after sitting over night --One injector on each side of the engine had an internal leak into the cylinder over night.

Thanks to a friend's recommendation and after my repair I would highly recommend Oregon Fuel Injection. They're a "First Class" company!
