all the part numbers match up for these. 86 gl wagon. 4wd auto, vs. 92 loyale five speed. every where i look the part numbers are the same for the fuel pump and idle air motor. but i have found some info stating the 86 has a carberator on it. i am confused. and i don't like the way my fuel pump is sounding. thanks in advance.

i haven't got that 86 parts car bought yet. if this is something else i can use, i will defenitley go for it. thank

Some 86's were carbed, some were not. Most 4WD's were carbed and most 2WD's were SPFI. But it's not a hard and fast rule.

 

You don't need to use a Subaru fuel pump. There's plenty of pumps that will work. They all make some type of whineing noise. It's the type of pump they are. You need a 50 psi capable pump. There's threads about using some early Ford F series truck pumps as they are cheap and availible.

Actually, it is totally a hard and fast rule for the non turbo cars in 86.

 

86 4wd WILL be a carbed car. Could be feedback or non-feedback depending Cali/49 State, but will be carbed.

 

2wds are SPFI

 

So, I wouldn't expect to be using the fuel pump from the 86 in the 91

yeah, i know they humm. mine just humms up and down with the blinker. every time the turn signal goes on and off, the pump changes its tune. didn't know if that is normal or not... thanks

Bad grounds - clean all the wiring harness grounding points.

That is true and I speak to that in my SPFI write up, but with anything that's over 20 years old.... it could have been converted to 4WD, or could have had a turbo and been swapped out..... you just never can tell for sure with used rigs. Mechanics have definately been all over it durring it's lifetime and who knows what's been done. We all know how easy a 4WD swap is on the EA82's and more than one EA82T has been swapped for an SPFI engine.

 

I should have been more clean in my original post. From the factory it should be carbed, but you just never know till you open the hood.
