New lb7 fuel injectors

Bruce - | 10/20/2019 12:01:00 pm

I already had a inch newinch fuel injector from Merchant, so all I had to do was order 7 more, which I did. Having said that for anyone that needs to change injectors on an LB7 this is by far the only way to go. I know that it is a pain in the butt to do this job, and this is the fourth set of injectors since I bought this truck back in 2004. I had to use rebuilt injectors in the past. These injectors, so far show the best balance rates ever. When the truck was was new the balance rates were not as good as the ones from Merchant. So to all those that have to do this job, the only way to go is with the injectors inch newinch from Merchant. I might also mention that the staff have always been very helpful as this is not my first purchase. Thanks to Eric Merchant and staff.......good job.......................!!!!!!!!!!!!!!

Installed the injectors over the weekend along with the Fass lift pump. 172,000 miles and runs like brand new again. The deluxe kit is awesome with everything needed and then some for the job, including injector puller and fuel line disconnecting tools. I liked the fact the injectors were new and not reconditioned and no core charge to worry about. Everything showed up on time and nicely packaged.

Great product fast shipping balance rates were excellent

So far so good

Brandon - | 10/12/2018 12:01:00 pm

I will have to try to update this after a year or so but I used 2 of these injectors along side the other factory 6 and the balance rates were dead on. Just have to see how long they'll last.

Awesome Company

I am so glad I did my research on buying injectors for my 2003 LB7 & found Merchant Automotive. I knew that replacing the injectors was a very labor intensive job & I was not going to take the chance installing rebuilt injectors. Your delukes kit was well worth the little extra cost. It had everything I needed to make the job much easier & a great warranty. Everything went great & my 2003 GMC 3500 runs great, pulls my 39ft. trailer better than it ever has, Thank you Merchant Automotive

Great product

Jeremy Bendlin - | 08/11/2019 12:01:00 pm

This is my first time ordering from Merchant Automotive. I purchased the fuel injectors with the deluxe install kit. I was impressed with the kit overall. Everthing installed with no issues and truck runs like new now. The only exception I had was the silcone provided for the valve covers. I was supplied Sil-Bond RTV 4500 silicone. Not sure I feel comfortable using it for the valve covers, so I used another product that I have used with success in the past. I definitely would recommend this kit for others. Nice having everthing in one kit. I also like the injector removal tool better than my factory style tool.

LB7 fuel injectors and deluxe install kit

Larry - | 04/10/2018 12:01:00 pm

Wow
What great customer service. I called twice asking questions and got straight forward answers no pressure sales. Then decided to purchase eight fuel injectors and deluxe installation kit on next phone call. I watched videos and ask questions everything for me went smooth I have a stock lb7 fuel mileage is at high teens in town and low to mid twenties on highway196500 on odometer at first change of injectors I like the thought of matching injectors only wish the test results came with the the quality injectors all packaged and capped in a quality heavy MA box All I can say is great job for M A well worth the phone calls thanks again

Nice 8 Pack Injector Kit

Bryan - | 04/10/2018 12:01:00 pm

This kit came with everything needed to do a quality repair. The injectors are nice because they are new and not re-manufactured.

Deluxe Kit Worth Every Penny

Greg - | 04/10/2018 12:01:00 pm

The deluxe kit comes with literally everything you need when doing an injector swap, and then some.

My LB7 severely needed new injectors and I came across this deluxe kit provided by Merchant Automotive. Filters, O rings, gaskets, new hardware for valve covers, fuel primer pump rebuild components, tools, fuel lines, AND brand new injectors with no core charge for under 3,500? This kit is bargain compared to what others are asking for just a set of re manufactured injectors and new lines.

Everything was neatly packaged and clearly labeled. The tools provided are handy, especially the injector puller. Replacement hardware for the two piece valve covers are a must have, and the fuel filter assembly spacer is a nice touch.

My 380k mile LB7 now idles smooth with zero haze, and has excellent oil pressure. I would recommend this kit to any LB7 owner looking to swap out injectors.

These are the injectors you are looking for

Steven - | 04/10/2018 12:01:00 pm

The stock injectors in my LB7 made it to around 160,000 on the stock tune. Knowing the LB7 has limits on a stock bottom end, I ordered some overpriced % over stock injectors with a matching injector pump. A little later I had my local mechanic drop in a DSP5 switch and EFI live tunes. Nothing a stock LB7 shouldn't handle. The first time I pushed the #3 tune to the limit, I lost 2 injectors, filled the crankcase with diesel and barely made it home. 21,000 miles is all I got out of them, from supposedly the best shop in the country at the time. I've only got a few thousand miles on the truck since installing these injectors but I have run the crap out of it regularly and so far so good. I have actually pushed these injectors harder and more often than the last set and there have been no problems at all. Plus no cores.

MA new injectors

Gary - | 04/10/2018 12:01:00 pm

Installed MA new injectors with the basic install kit in my 2003 GMC 3500 witch has approximately 137,000 miles on it. The main reason I went with the MA new injectors as opposed to reman Bosch is because I didn't want to deal with time and money of core charges. Before & After the injectors arrived and I started the installation I had couple of questions for MA, they answered the phone with a real person on the other end great customer service. So far I am happy with the MA new injectors my first test drive my truck average 25.4 mpg over 75 mile highway drive, that's pretty bad ass for a 4 door dually. So far the only negative thing I can say is that the basic install kit is a little priced. I will be ordering a lift pump next.
