Default 1992 LT1 headers and Fuel lines


overview

fuel lines wrapped in heat shield

close up

possible space between lines and header tube, I can get a finger in but that's about it...
So I replaced the exhaust manifolds with headers. I have a mechanic friend who is very worried about the close proximity of the stainless steel fuel lines to the headers. They have the metal spring looking wrap I would assume is for protection and I put high temp wrapping around them to help separate them from the headers. They are very close but if I remember correctly they were dam close with the exhaust manifolds in place also, from the factory. Is this something I should really worry about, I know I'm not the first to put headers on a 92 LT1, are there issues and if so how did you deal with it?

Thanks
Steve

Been running headers on my 93 for near 10 years. Never worried about and never had a problem, you should be fine.

How close are your fuel lines to your headers?

my 92 had headers on it when i bought it, didn't seem to be a problem. plenty of other issues though. i did put some heat sleeving on it though, should be running within a week or so. just getting the fuel filter changed was quite fun, wrapped the 2 tubes when it was off

don't assume cause others had no issues, that you will not. different headers fit differently. my first headers on my 93 LT1 were way to close to fuel lines as well as rubbed a/c box. I ran new stainless braided fuel lines from rail To filter and re routed away from headers. and modified ac box. now I have since installed better Long tube headers and they fit WAY better. stock fuel lines would have worked and do not rub ac box. and save about 4 hours on a plug change. painted headers old poor fitting, ceramic coated fit awesome.












black headers are the ones

I bought the flex line in a 20' length and installed the AN fittings and thenbought AN to stock conversion fittings from here. http://www.purechoicemotorsports.com...rod/prd233.htm

the link is directly to their pre made up lines. I had already bought the line before I found this place. they are awesome to talk to over phone. will know exactly what you need and hook you up. you can transition under car like I did at filter and return line also has coupler right next to filter. word of advise if you make up lines yourself use Russel or equivalent fittings. same with rail adapter fittings. I used cheap ebay at first and before too long it leaked. there are 2 styles you can use at fuel rail. a snap on and screw on. definitely get the screw on. my old shorties were Pacesetter knockoffs. good luck changing plugs lol. they made plug changes a pia.
