306 EFI build - blazinchuck - 12-30-2011
also, when i 1st did my efi swap...i had to lose my schrader valve. so a while back...i found a tbird with the fuel connectors and pressure valve on the pass side like what i have.
any problems if i go with this for this 306? is it better or worst than the mustang HO fuel rail?
injectors:
the guy that i got the gt40 intake from gave me 2 sets of 19lb injectors. doesnt look like any of them have been rebuilt, but there was a bcbroncos with what looks like the upper/lower o-rings for injectors(can anyone confirm this)
should i do anything with these injectors? pop test? rebuild? or use what im using right now with the 5.0?
and in one of the pics...you can see a small crack in the line. this is the front cross-over fuel rail line. it looks like a grey protective jacket...yall think this is ok? i dont see any damage under it at all. thanks again guys

yeah, a 97 would have had the non-P heads. Balancer would be the 3 bolt type. I have robbed one off of a 97 before.
Not sure if you've gone to the 90 degree thermostat housing yet. You'll need it.
You did a good job cleaning that engine up. Keep it up and I'll send a few your way

ayone got thoughts on the intake hitting the valve cover?? i dont want to buy a spacer.
i want to cut or remove that pressed in 90 and maybe thread it for a plug??? never tried to pull one of these out

heck, i think it wouldn't be hard at all to remove the fitting and tap it. I'd use a pipe thread on it. While you are at it, I'd tap the lower intake (for the EGR port) and plug it off, like I did on my build thread.

Yes, those are the injector o-rings. I would soak the injectors in some sea foam for a night and then do a pop test on them.

If you need to upgrade I have several sets of 24 lbs injectors I can swap for something.
The fuel rails look like they should work. I don't think you need to up grade them to billet logs...yet:bdent:
The Trick Flow set up works very well with fuel injection. Their stuff even allows for further mods down the road if needed. If I remember correctly, the engine Carl W. ran in his Bronco had a TFS head/cam combo...

I believe that stuff is cast aluminum so keep in mind if you screw it up you will be going to the junk yard for a replacement

The years of the non-P head was 96-97.5 so some of the 97 will have the dreaded P heads.

[COLOR="Red"]Should be no difference in fuel rails until you start dealing with the Cobra stuff. The fuel press reg will be different.

o-rings should be cheap from the parts house... i think.
should i do anything with these injectors? pop test? rebuild? or use what im using right now with the 5.0?
go with what you have for now. 19lb is stock for these motors. I would test/ clean for spares though. plenty of good write-ups for that.
and in one of the pics...you can see a small crack in the line. this is the front cross-over fuel rail line. it looks like a grey protective jacket...yall think this is ok? i dont see any damage under it at all. thanks again guys Do a pressure test with the air on it and see if it leaks. if so, you can cut it off and replace it with high pressure efi hose and efi clamps.
