I am happily running a DW 200 (255 LPH) pump on a basically stock 3800 SC Series II engine with a 3.4 pulley. It is quiet, has a three year "No Fault" warranty, and a decent price.

Lifetime warranty, they claim it outflows the Walbro, and it's cheaper too! I would like to know how many people are running it and how these pumps are working out in the real world. If they work as advertised, this would be a better alternative than the Walbro or even the Deatschwerks pumps.

The Deatschwerks pumps are nice, but they require modification to the Fiero sending unit in order to use them. If the HFP pumps are as good as advertised, they would probably be the best ones to use for 3800 SC and Turbo swaps.

I'm sure I'm going to get crap for this, but I'm just running the stock Fiero pump.

I bought that hfp255lph pump but havent dropped the tank to install It yet. What is entailed in the wiring ? Is it plug and play or do I have to solder the correct connector on and if so where do i get the connector from?Thanks, pics would be awesome.

HFP's website has pictures of the pump. It looks like the pump does have different wiring terminals than an OE/stock Fiero pump, and the kit includes a new harness connector and pigtail. So yes, it does appear as though you are going to need to splice in the supplied connector pigtail when you upgrade to the HFP pump.

Aftermarket performance fuel pumps typically draw more current (amps) than factory pumps do. So if you are installing any aftermarket performance fuel pump into a Fiero tank, I highly recommend you do the "hot wire" mod as I have it explained here: http://www.gmtuners.com/fiero/hot_wire.htm

The 255lph pump is my second pump purchased from HFP. I got the 320lph and the 255lph pumps. The 320lph is supposedly installed in a 3800 turbo and the 255lph will be installed in a highly modded 3800SC this summer. I will post up some pics of the 255lph pump if I can get to it easily enough.

I did not install the 320lph but plan on installing the 255lph one. If my 88 coup had the 2.8 V6 it would have been installed already.

Your right about that. I'm looking for a way isolate the pump. Using the same clamp as you are. haven't found anything yet to quiet it up.

Get an exhaust hanger bracket from the parts store that has a rubber strip with holes cut in it (this rubber strip is heavy duty as it is designed to hold up exhaust). Mount the clamp holding your pump to the rubber strip and then mount the other end of the rubber strip to the chassis (cut the rubber strip to the desired length) - leaving enough length so the fuel pump clamp isn't touching the metal chassis/body of the car. This will allow the pump to move a little bit so make sure that isn't going to cause problems. The rubber hanger strip should add quite a bit of isolation to the pump body which should quiet it up significantly.
