Hey yall, Im Julio and I live in Austin Texas. I recently purchased a non running 1989 Mazda RX7 S5 Turbo. Wanted a sports car and thought I should make me a project car and I've always wanted one of these cars. It has 124k with 90K on a motor from Japan. I don't know much about how to work on cars but im determined to learn. Starting to buy parts to work on it and first step is to change out the fuel lines. Anyone have experience with this im all open ears on tips and tricks.

 

Does the engine turn over or start? If so, do a compression test. You can get a compression tester from Advance Auto. Remove the check valve from the tester before doing the test.

Thanks! I forgot to add the guy I bought it from said it turns but he thinks it wasn't getting enough fuel to the engine. He told me he recommended replacing the fuel lines and possibly the fuel tank. Im slowly getting parts to get it replaced. Was trying to find out where i could get stainless steel lines because I want to track the car out eventually.

 

I wouldn't start spending my money on SS lines yet. Just replace all the rubber fuel hose with some quality new rubber fuel hose. If the motor doesn't make compression then your fuel system won't matter 😉

Id imagine the tank is fine so Long as there is t a hole in it.

 

Thanks for the tip! Im going to take it down and put a normal rubber hose in it and see if that does the trick.

 

Normal hose..NO!
you'll need to replace the fuel lines with HIGH PRESSURE fuel lines not any regular hose.

NOTE: any more TECHNICAL questions can be asked IN Tech where they should rightfully be.
Good luck.

 

Hey I'm from right around Austin, TX! I'm stationed in Florida right now but I visit the Austin area pretty often. Maybe if I'm in town with nothing to do I can come help out if you're still having issues? Haha. I second styx though, the tech section will get a lot more exposure to people that can really help you out. It's always best to try and diagnose the problem before throwing money and parts at the car. I've learned from experience all too well.
