I just got done taking the old lines out, and I'm going to be putting the new lines in after bending them. My question is about the third fuel line. It goes up and over the trans, then into the canister near the air filter. Is there any way to eliminate this? My educated guess would be this is a "vapor" line that carries fuel vapors to the canister...then it's put into the headers via the AIR. I don't have AIR anymore since I put in longtube hearders. Can I just unhook everything? Will I get a code?

Also...Instead of putting the lines back to the stock position in the engine bay...I'm going to stop the hard lines right as they cross the firewall. This way if I decide to go with the Holley Stealth Ram I won't have to route the lines back. From those hard lines I'll have braided steel lines to the stock TPI plug ins. Does anyone know the specs on the fuel lines and the fittings?

Anyone who done this before? What pitfalls should I look for?

for fittings you'll need adaptors to go from m-16 and m18 pipe thread to 6AN, you need to male adaptors for the hard lines at the fuel rails, and two female for the lines as they cross the firewall, after that it's just whatever angle of a 6AN fitting you need.

if your talking about the carcole canister, you can keep it or get rid of it. the line that goes to it is for vapors from the tank, it than filters the vapors through the canister and then purges the canister to the throttle body to be reintroduced to the combustion chamber. that is my understanding of it, i need to study it a little more. helps with HC emissions.

 

Where can I get some stainless steel unbent lines? I need to get them ASAP. I have a week to get these lines bent and back in the car, and that's aside from working 60 hours. I wanna go stainless if I can, but if I need to I was thinking of using murray's (local parts store) brake line sprayed with some rustproof coating.

If I elinimate the evap line...what do I put on the line coming off the tank? When I unhooked it, a little liquid gas came out. I'm thinking I might need some type of filter that will keep liquid in but let vapor escape.

Are those too big? What will bigger lines do to my fuel system? Will bigger lines nessecatate the need for an adjustable regulator?

bout some 3/8 inch aluminum fuel line from the local speed shop. Along with that I bought 6 feet of braided fuel line, 4 female 6AN fittings for the braided line, and 2 male 6AN fittings that I'll flair onto the hardline at the firewall. I had forgotten the sizes that were posted here for the engine fuel rail...so tomorrow i'll go order double male adaptors with 6AN on one side and the correct M size on the other. The only thing I haven't figured out is how to connect the hard line to a stock style fuel filter. The female connectors on the filter are 5/16 (we think), but they didn't have any 5/16 adaptors for the slipon rubber hose. Anyone know the thread size for the filter? M-18? The bigger of the two mail fittings on my stock lines with the filter.

I will post pics at least of final product...maybe installation pics.

Are you talking about the fuel filter fittings? These are the ones I use.

so the fuel filter is M16 female, and I will need M16 and M18 male fittings to plug into the engine fuel rail?

I dont have AIM. I can tell you that the fuel rail fittings are usually a 16mm for the feed line and the 14mm is for the return line.

Well I took the pump out today since i received it earlier than I expected. It took me a good 2-3 hours to get the tank out. I had ALREADY disconnected the rear end, unbolted the exhaust from it's hangers, and taken the fuel lines off. The problem is that my exhaust is custom...it's a custom y-pipe from my longtubes, into a 3 inch intermediate cut to face straight forward, into a flowmaster. I ended up cutting the pipe right between the y-pipe and the 3 inch intermediate, then disconnected the intermediate from the flowmasters. I was stuck for a while trying to take it out without cutting up the exhaust, but even after that it was still not easy.

The main problem was that the panhard bar "mount bar" wouldn't come off on the driverside. The nut came off but the bolt wouldn't go back through. This created a problem of clearing the filler neck. I finally got it...but it f'd me up. I didn't expect that much hassle. I'm hoping I won't have to manuver it too much to get it back in. Looks like I'm getting that new y-pipe I wanted to eventually get. LOL

When I went to the speed shop in my area (Ramchargers) the guys I talked to said they had never worked with anyone replacing their fuel line for a fuel injected car. My filter and engine fuel rail line connections created a problem because all the fittings they use are AN. I got it all figured out, and spent about $120 for everything. I'll post pics before and after installation along with part numbers...but basically I used aluminum hard line (surprisingly the cheapest part for amount of product...at $20 for 25 feet), 6 feet steel braided line, some AN fittings for my hard line and for the braided line.

Anyone with questions on removal and installation of a fuel pump, or new fuel lines drop me a line or post here.
