I am doing a 3800 L67 swap in my fiero, and I am trying to find a fuel pump that will be able to handle the increase fuel needs.

I think that the FP376 ACDelco fuel pump will work, I think it is rated at 203 Liters per hour.

If anyone else with the 3800 swap can give me any tips or tell me what fuel pump they are running I would appreciate it.

Thanks,
Kyle

Great fuel pump info for swaps:

I've heard good things about the Delco EP381.
Heard it handles the fuel demands and not as load as the Warbers. And have found the prices resonable. Just make sure it is Delco.

I am running two different fuel pumps on 3800 SC engines at this moment. One engine is basically a stock 3800 SC Series II with a 3.4 pulley and a custom exhaust. I am using a Deatsch Werks (DW 200) fuel pump on that one. This pump is 255 lph and has a "no fault" three year warranty. It is also the quietest pump that I have ever heard. I also have a Corvette fuel pump on a 3800 SC Series III engine with mods (ZZP intercooler, N* TV, VS cam, custom exhaust, and a 3.4 pulley). I have run this one fro about three years and 20000 plus miles with no issues.

I used to have a Walbro 255 but upgraded to a Walbro 400 lphr pump. Probably overkill on my setup, but that's alright. I'd definitely recommend a Walbro 255.

------------------

I used to use the EP376 on all my swaps but have now swapped over to using EP381 on future swaps. I tried using the Walbro pump on 2 past swaps but the noise was enough for the owner to want it swapped out and the other would over heat in sumer time when tank was low so will not use them again.

I can not even hear the DW 300 running.

Same for the DW 200 (255 lph).

Maybe I'm strange but I enjoy hearing a loud fuel pump so I know it's always working. I never had any issues with my Walbro 255. I love my Walbro 400 now. I got enough fuel for when I go Turbo down the road.

I always had good luck with the Walbro 255

I followed JB on this one and so far so good - e85 for 6 mos with no problems.

I used a Aeromotive 340 and it was totally silent, I've since switched it out for a DW300 because I am playing for E86 next spring. The DW300 is louder than the aeromotive 340 but both are silent compared to the walbro 255.

1985 GT 3800SC (swap in progress)

I've decided to go with the Delco EP381 from Autozone

I'll be picking it up tomorrow on my break at work and hopefully get it installed in place of the old sending unit.
I think using this little trick will help me fix my gauge, as the needle jumps all over the place even with new gauges.


Hopefully after I clean the resistor and put in a new fuel pump then I can get the tank back in and be that much closer to having a 3800 SC Fiero

As I have stated in countless other threads... PLEASE - do NOT use an EP-376 fuel pump with a 3800 SC swap. Just use an EP-381 instead (as long as you aren't making more than about 300 crank HP).

If your 3800 SC is going to make more than 300 crank HP, you will need a higher volume pump than an EP-381 and there are plenty of different aftermarket performance pumps out there to choose from.

As with any 3800 SC swap, I recommend you perform the fuel pump "hot wire" mod that is explained here: http://www.gmtuners.com/fiero/hot_wire.htm to ensure your new fuel pump gets the power it needs to perform correctly.
