I need some advise...

I went to my local parts store and ordered a new fuel pump to replace the original OEM 85SE pump. I was told that the replacement Carter pump was a direct bolt-up replacement but now that I have it in my hands I want to make sure it's correct.

I've attached a picture from the FSM of the OEM part and my question is about the regulator/dampener at the end of the output side. The new pump doesn't have anything like it. Do I need to add something inline to compensate for whatever is missing?

btw - Mazda wanted $936 for a new one.

Also...while I'm asking, does the return line on an SE have to be FI rated or can I use cheaper non-FI fuel hose?

Thanks!

 

the return hose should be rated to handle fuel but does not need to be fuel injection rated due to it being only a return hose. i'm not a big fan of non oem indirect replacements. the fuel pump will work but its an odd fit..

 

Is anybody a real fan of non oem replacements?

I wouldn't spend $1,000 on a replacement fuel pump when I can get one for ~$100 with a regulator to boot!

I would think that the return line can be non-FI rated as there won't be that much pressure in there. If you want to be safe, I would go ahead and buy it anyways.

i just went down to look at my old pump and I don't have anything like that either. It just looks like where the power runs to the pump.

 

It was kind of funny when the Mazda guy gave me the price. He said "9-36-95" and I thought he was giving me the part number!! So I said.."and what's the price?" and he replied "that's it".

Umm...I guess I'll have to go aftermarket.

At least the gaskets for the fuel tank were a reasonable price.

 

why not stay with an oem pump? just post a want to buy ad here on the forum in the 1st gen classifides for a good used pump.

 

hey gman

i have a spare gsl-se fuel pump if you need. 30 bucks...

pm me if you are interested

 

Thanks Jimmy. I'd pay 30 bucks just to take a spin in your car one day.

I'm wondering if I'm doing myself any favours by installing a 25 year old pump. I actually have an old SE pump but I thought that while I've got the fuel tank out, installing upgraded fuel lines (hey...the lines are actually yours too!!) that I'd install a new pump too. Does that sound crazy???

I appreciate everyone's thoughts. I'm still wondering about the thingy in the picture though. Anyone?

Thanks

 

Looks like a pulsation dampener.
