Hi everyone.

 

Since swapping my fuel tank for a new one (and relocating it) the fuel pump has developed (getting worse and worse) a loud vibrating grinding type noise and the car is really hard to start and runs like crap.

 

Trying to find someone who can check the fuel pressure tomorrow, I'm away from home and have no tools!

 

Any ideas about a systematic approach to sorting this please?

Your Subie's Fuel Pump is Electric and it came Stock Located Next to the Tank...

if you Moved the Tank, you Should moved that Fuel pump with it, 'cos if it Stays too Long from the Tank, it Might Suck Air and since Fuel Pumps are Cooled by the Passing Fuel, Suckin' Air will Overheat & Damage the Fuel Pump.

 

Also it Should be Placed as the Stock Placement Was, in order to allow it to Obtain a Free Fuel Flow...

 

Hope this can Help.

Kind Regards.

Start by checking the fuel pressure.

thanks, yes, I think I have it in a decent position - like the stock position, wide bore pipe and short from tank to pump, it's the awful noise that's coming from it that is worrying me.

Start by checking the fuel pressure.

 

after the regulator or just the raw pump pressure?

 

can you advise the normal range?

You need to tee into the supply line to the rail.Don`t deadhead the pump.

 

Around 36psi above atmospheric,IIRC.Less w/running engine w/intake vacuum.

thanks, obvious now that you've said it - T off, I'll have to take it to a garage anyhow, just can't stand not knowing myself what/how to do it.

 

Thanks again - pressure at the rail - place to start.
