In my opinion the 703's are supper for jammen and cruiseing on the highway.

Because of the higher flow rate, it tends to warm up a little slower. It's running rich with that higher flow rate, which actually sucks heat out. (liquid to vapor, change of state, is also is what your AC uses). No *hit. So with 703's on allot of short trips I see maybe 15, but shoot up well over 20 MPG running in closed loop on the highway. There it's within parameters, and the 02 sensor is controlling it neat. Looking to swap out my 703's for 18-19 Lb/hr/ four hole injectors, so while running in "default pulse width", cold , it is not getting more than it needs, or wants. I'm pretty sure on that.

 

Never thought about those, what doners can those be gotten from? Makes total sense though!

Brain fart! Ding ding, the ford 5.0!

 

I tried and failed to find "ford yellows" at one pick & pull once. Guess a bunch of Mustangs ran them. Ebay had some stuff. I'm currently up to my neck in alligators, but do need to solve that one myself. besides the 6 703's I'm runnen, I have two more. Guess I need to buy the replacements before I can sell the 703's.

To back up and be clear. The 703's work great at temp. Just when its cold, running on a preset "pulse width" is when the higher flow is a problem. Sorry of me I can't post it. 21, 22 Lbs/ hr for the 703?, as opposed to the 18.5 the computer is programed for.

I should look! I spent a load of time on it. It does get tricky. There might be yellow 19# four hole injectors, with the EV-1 connectors, that you don't want. Maybe someone else here can help. Might be their are "solid" ones without a metal band, and crimp. I did write down some numbers.....somewhere
