370's Install questions

[BCFAST]

I have a set of 370s in the box. Finally have time to work on the truck tomorrow and need to know a couple things, guys: What kind of job is it? The line-work seems straight forward, but is it tough getting the injectors out/in? and #2, will they work with my little #12 plate? My exhaust is 3"-4"-5", turbo is stock, and a BHAF.

BCFAST,



Some time ago KOA MAN posted instructions to make a simple slide hammer. Your going to need one to screw onto the injector and "hammer" it out. Clean your engine real well to minimize the dirt problem. Your going to need to remove the "rack" ie the injector lines. Don't bend them out of the way. Mine were a "bugger" to pull. I used a copious amount of carb cleaner to help loosen them. Do you have new o-rings to put in? The injectors use a square sided o-ring to keep moisture out. Also, you may want to have some copper gaskets for the fuel return line in case just in case. They usually can be re-used. One other thing on mine was the banjo seal on the return line to the filter. Darn thing fell apart and it was saturday night



I don't have my records on hand but there is a wealth of info out there from old posts. Some of the online parts suppliers have info to download too.



When I buttoned mine up, I left the injector lines slightly loose and used the fuel primer to bleed most of the air out then snugged up the lines. Once mine fired, I bled each line out then torqued to spec afterwards.



Will they work? I would think so!

One more thing, do you have new copper gaskets with the injectors? I forget what size the jury settled on.

BCFAST,



The injector install is pretty easy. I made a puller out of a 3 1/2" long 1" pipe, 1/2" all-thread, 1 - 1/2" washer, 2 - 1/2" nuts, and a metric nut to fit the injector. My hardware store had the metric nut, but I don't know if everyone is that lucky. I gave each injector about a turn with the wrench and they pulled right out. Worked great, no prying or hammering. I think I got it done it about an hour and a half making sure that everything was clean in the bores.



As for working with a #12, I am pretty sure that everyone with a 215hp pump is fine with these injectors. The copper washers are supposed to be the thin ones.



Have fun.

Make the slide hammer if at all possible.

I did mine w/o it, and it took 4. 5 hours. Thankfully, the injectors in the last 3 cylinders were easier to get out than the first 3.

I did mine with a vice grip, and a crow bar. I was dousing them with Kroil for at least a month prior to removing them.

I had to turn my idle up almost 200 rpm's when done.

I'm very happy with mine!!

Even with my Charlie Brown luck, 40 minutes out, 1 1/2 hours back in, started on third crank!



I bought Piers two tools to pull them.

I didn't think it was a bad project at all. I too was spraying mine with Kroil every couple days for at least a month before hand. I'm sure this had to help.



The best/easiest way to get the metric nut you need, is to buy a wheel lug nut. Auto Zone or any other auto parts store will have one. 14mm x 16 if I remember correctly, but I'm not 100% sure on this, sorry.



I used the lug nut screwed onto the injector and used a prybar to pry (on a head bolt) the injectors out. I didn't have to apply much force to get them out, but it would have been impossible to get them out otherwise.



If you want to use a slide hammer, just get the wheel stud to match the lug nut and screw the nut onto the injector and then the stud on the nut.



I have to give credit where it is due. "Hemi-Dart" was very helpful letting me borrow his wheel stud/lug nut "puller" when it came time for me to perform this task. Thanks Hemi I have since bought my own home-made injector "puller".



I hope this helps,

Ryan

Yeah, but at least you didn't have to buy him a first class plane ticket.



Mine went in easy. MDW had a slide hammer made out of a lugnut, a wheel stud and a big bolt. just short enough to get the 5 and 6 injector out.



The fun part is sliding a dually sideways on dry pavement afterwards.
