Let me ad some fuel to the fire here . I have a 99xj and found some from a 99-200 sebring v6 they are orange will these work? I do not have them in my possesion yet but can get them for 20$ they were pulled from a running v. I will look to see what the serial # is on them .I assume they should be the 784" if they are going to work correct?

That is a great sheet for the 703's. Has anyone built a sheet similar for the 784's.

I am using a set of 0280155917 injectors in my 99 with great results. I got a set of 10 like new pull-offs on Ebay for less than $100. Haven't noticed any throttle response improvements/losses, but my idle is now really smooth and my MPG defiantly went up. I haven't calculated it yet, but normally my idiot light would come on around 250 miles driven. Right now I am at around 200 miles and still sitting at half a tank.

Thats awesome man for everyone else who has had them for a while what kind of mileage increase did you get? I was getting pretty bad mileage so i did a couple of things (bought a cold air intake and throttle body spacer) which helped, but im just looking to know what kind of improvements there was like 2 more mpg or what? that would put me to almost 18 19 in town which i would love. I mean im 17 and i drive 300 miles a week to school, work, and everywhere else so bring it on!

I know they came on some of Ford's V10 6.8L trucks which is why they came in a set of 10 for me. Here is the best list I found:


FORD CROWN VICTORIA (2003 - 2004)
FORD E SUPER DUTY (2000 - 2002)
FORD E-350 ECONOLINE (2000 - 2003)
FORD E-450 ECONOLINE 2003
FORD E-550 SUPER DUTY CUSTOM 2003
FORD EXCURSION (2000 - 2005)
FORD F-250 SUPER DUTY (2000 - 2004)
FORD F-350 SUPER DUTY (2000 - 2004)
FORD F-450 SUPER DUTY (2000 - 2004)
FORD F-550 SUPER DUTY (2000 - 2004)
LINCOLN TOWN CAR CARTIER 2003
LINCOLN TOWN CAR EXECUTIVE (2003 - 2004)
LINCOLN TOWN CAR SIGNATURE (2003 - 2004)
LINCOLN TOWN CAR ULTIMATE 2004
MERCURY GRAND MARQUIS (2003 - 2004)

I have four of them left over, I was just going keep them as spares but if anyone is interested in buying them send me a PM. I'd let them go cheap and you'd only need to find two more.

Will these only work with 97+? my understanding is 95+ all operate at 49 psi +/- 5 at the rail. So would it make a difference, or is it a fit issue?
