The car I boughts fuel lines were leaking so they were replaced with high pressure rubber lines. Will these not hold enough pressure and cause problems? Just wondering if this would cause the motor not to start. It starts with starting fluid only because the fuel pump is fried. I have a new pump that works, but only wondering if rubber lines will create a problem. The reason I ask is because the car was never tried to start with the rubber lines.

 

No...as long as you use fuel injection hose specifically...even using non FI hose probably wouldnt keep the car from starting (how could it), but it would be very unsafe!

 

I dont know that they are FI specifically, but he said they were high pressure and he got them at a parts store, so I hope the store would give them the right stuff.

 

It will say on the hose..high pressure fuel line or soemthing to that effect.

It'd be hard to mess up if he asked specifically..Carbs operate at like 5-7 psi and FI is like upwards of 60-70 psi.

 

DId you cross up your fuel lines? Did you prime the system?

 

Have you even put in the new pump yet or your saying you have one that works your going to put in? I'd be more worried about swapping pumps that whether you bought the rat, I mean right () hose...check the lines like J said too.

 

I doubt they primed it. How the hell would I do that to ensure its ok?

 

Jumper the yellow test connector in your engine bay by the shock tower. Turn ignition on (DONT START THE CAR). Listen for pump, look for leaks, let run for about 1 min.

Have a new pump Im gonna put in, after I dremel the old screws out. Why should I be worried about switching pumps?

 

When you say "run", you mean just let it sit like that for a minute, with the car off right? And, in my 88 the jumper connector was yellow, but in this 87 its green, same thing right?

 

You said you old fuel pump is "fried'..thats why...I'd be MORE worried about switching that, as in get it switched, more than whether you purchased the right fuel hose. As far as getting the car started that is.

 

Gotcha, the old pump is just shot, but I think its weird seeing the car only has 64k on the clock. And in my 87 the yellow connector is green, same thing right? IN my 88 it was yellow.

 

It better be yellow on the 87 too, or you got the wrong one.

Ive NEVER seen a green fuel pump jumper connector.

its in the same spot, and same kind of connector-Ill start a thread on it

 

Okay, I might just get proven wrong.

 

Never on the 8 rx7's I've seen has the fuel pump connector been green.

 

Ill get a picture then
