I have some spar egine parts laying around from blown engines I took apart.


Both JDm as US as Euro spec.

I found out that from the 2 fuel line sets I have (different spec), that they are different.

One has a fuel pressure regulator (the pot at the fuel exit off the sec fuel line) has one vac connection, the other one has got 2.


Now, since I susect that my injectors are leaking (1 vac line) I decided to switch out the full fuel deliery system (prim and sec injectors).

Now the othe system has the pot with 2 vac lines. The workshop handbook doesn't mention this difference.

Can I just leave the upper vac line connection open and the lowerone connected to vac (like the pot with one vac connection) does the upper one need to be capped?

Any info would be great

 

The euro spec cars apparently have 2 solenoids for the FPR. I know that people typically T the two lines together when replacing the stock dual line FPR with an aftermarket FPR. You could try that or just hook up the system based on the US specs (using the single solenoid).

 

Thanks, but I'm full non seq with no solenoids whatsoever. sorry, forgot to mention that.

 

Then just T the two together to your source like I mentioned above.
