Re: Trunk Fuel Resistor

While thinking about the sad state of my SVX and hoping for warmer weather, the thought of the fuel transfer/jet pump causing this issue also crossed my mind. The fuel level like mentioned before has been/is low and it makes me wonder.

When the garage warms up I want to remove the fuel tank access cover and take a peek at the pump(s).

Re: Trunk Fuel Resistor

I got a chance to work on the car today. I removed the cover in the trunk to access the top of the fuel tank. I disconnected the hoses (a real PIA) and unscrewed the fuel cap.

Peaking inside I was happy to see a clean looking tank. The fuel level was very low and the pump was not fully submerged but the filter was still in gasoline. It is a very tight fit to see anything. I then put everything back into place and while still in the rear of the car I attempted to start the engine. I tried to listen for anything from the fuel pump but nothing was heard. For those keeping track, this was attempted with the fuel module and resistor connected.

I am looking at replacement fuel pumps but nothing OEM is available. The highest rated alternative is from Walbro but it appears to require modification to fit. Here is the unit I am currently contemplating - LINK.

Re: Trunk Fuel Resistor

I've replaced the fuel pump on my SVX (because I'd not correctly diagnosed a bad MAF plug...). It was a major pain, was very annoyed when I found it was unnecessary in the end... I got some generic pump from a local auto parts store, it came with some parts to wire it into the existing wiring (maybe to reuse the original pumps connector or something like that). I would not say it required any other modifications to install.

I hope I never have to change the fuel pump ever again.

Best of luck!
Ian.

Ugh. Sounds like a real pain. Has the generic pump been working well for you?

Re: Trunk Fuel Resistor

I've had no problems from the generic pump, although I've sold that car now, the current owner has reported any problems either. I probably ran with the generic fuel pump for at least a year, if not two, as my daily driver (10k to 15k miles per year).

Re: Trunk Fuel Resistor

I appreciate the heads-up on the unit available for sale - it is a kind gesture.

I know this thread has become long and possibly hard to follow but I am currently looking to replace the fuel pump as part of my next task.

Re: Trunk Fuel Resistor

If you haven't pulled it to bits yet, you could try powering the pump to see if it works. There is a connector under the rear seat that you could connect a 12V battery up to see if it does.

Re: Trunk Fuel Resistor

This is the fuel pump that I using to replace my stock pump:
https://www.oreillyauto.com/detail/b...992/subaru/svx

I thought this was a good diagnostic/guess/investigation/replace-things-and-hope-it-helps step. But after doing it once, I wouldn't do it again unless I was sure that fuel pump really needed replacing.

Good luck!
Ian.
