OTC Master Fuel Injection Kit (6550)

very good quality. i think this unit has every connecter there is. Even fit my 84 911 with motronic F.I. Although this unit is made in taiwan, i'v never seen a better made set, all with quick disconnects. You will still need your specific auto service manual for proper hook-up and #readings.

This kit has a very good selection of fittings to test fuel pressure. I did Tun into an issue where I needed to test the fuel pressure coming from the lift pump on a 6.7 power stroke and had no fitting in the kit that would work for this application, so I had to fabricate my own. I wish it would also come with a compu-check quick connect to test fuel pressure on bigger diesel engines. Other than that, it’s a very good gauge with wide variety of fittings for gas engines, as far as diesel goes, it does lack fittings

This is really amazing, I could find something better than this, I have bought two actually, the kit miss 4 fuel line disconnect tools, I don't know why OTC did this, since this is an expensive item already, they should include it, but you can see my others reviews, to see the item you need to buy to complete your kit , I use it at my shop [...]

I bough this kit in 2011. I have used about four times. the other day was going to used and the red fuel lines just crumble, I always drained the fuel out of it,,, was trying to see if I could put new lines to it.. I was surprise the lines just disintegrated this way...

Gage is large, plenty of simple to use adapters to cover your fuel system repair needs. Nice case to keep everything contained safe and secure.

My old kit finally gave it up after about 25 years (different brand) so I bought this to replace it.Seems like a well rounded kit, excellent value. Didn't think I needed the next one up, and probably won't.

DONT EXPECT FOR THE CASE TO HOLD ALL THE FUEL LINE CONNECTIONS THEY ALWAYS FALL OUT. WORST THING EVER MADE

I use this kit every week. It comes with so many fittings that you can disassemble some to hook a rubber hose into the return line for "deadhead" pressure tests. Still works like new.

very complete set. Very fast shipping. Good value for what you get in the kit

Looks good and seems to have everything I need. Used a few times and works great.

Fast delivery.5 stars

Works as described.
