Fuel injector question ...

Well I went to install my 60# injectors today and I ran into some trouble.

I'm using my stock '96 rails (return style) on a PI intake. I had no issues with the stock 19# injectors when I did my full PI swap 3 yrs ago. The injectors fit fine.

The injectors I'm switching to are SD/Motoron 60#'ers. I noticed they are just about 1/8" shorter then the 19's. When I install the injectors and fuel rails I can still move the injectors up and down that 1/8". In other words, if I seat the injector all the way into the rail, then tighten the rail down, the injector is not fully seated into the intake. I can push the injector down about 1/8", which in turn causes it to not be fully seated in the rail. Understand what I'm trying to say?

This is all new to me so I don't know if this is normal or not. I'd rather ask dumb sounding questions on here before I email Kurgan's with my non informed questions.

Is there something on the injectors themselves that can be changed?

Did I get the wrong injectors?

I thought they'd be a direct swap from OEM. Any thoughts guys?

Ok here's a pic of the difference in the height of the injectors. It hard to see in the pic and it isn't very much, but it apparently enough.



Does anyone have any clues?

Thanks guys.

I put the same post up on ModdedMustangs also ... Fuel injector question


There's some interesting info in there if you feel like reading. Bob Kurgan is a member over there (Flyin Hawaiin) and chimed in yesterday while I was out. I hoping he pops back in there today.


Good new is my clutch fork and pivot ball came in last night and I'm headed out to put the transmission in shortly. That will allow me to get the reat of the accessories back on the motor and start installing the turbo kit. :awesomework:

Yeah .... kind of. lol

The new injectors mic'd out at .095" shorter then the stock ones. When I install the rails on the intake I can move the injectors up and down that 1/10 of an inch. I'm not sure if that's normal or not. I'd like to find out my options before I put gas through them and then not be able to return them because they've been used. I don't have $400 for another set of injectors.

I'll wait and see if Kurgan chimes in over there again. If not I'll fire him off an email on Monday and see what's up.

He could, but if its like most companies, unless they install parts, they usually don't even have the slightest of clues. So instead they'll make shit up.

Frosty I bought my MAF, injectors and fuel pump from Kurgan's Motorsports. Bob Kurgan responded to my thread on MM so I'll wait until after the weekend to see if he stops back in over there. If not I'll contact him on Monday.

I'm new to all this so I just wanted to see if the movement of the injectors is normal before I sent him an email for something that might be a non issue.
