stock fuel pump is 88 lph, which is enough for 19# injectors, but not enough for aftermarket H/C/I. I would recommend the 190 lph from FMS its like 200 bucks i think and is easily installed in like 2 hours or less by anyone. That should support you up until u get above 30# injectors.

The stock 88 is not enough for the 19# injectors if they're used to the max. You may get by with the 19's, but you're gonna need more pump. The 190 should cover all your needs.

My stock fuel pump was a 95lph...

I ran with my stock fuel pump on my (in sig) h/c/i for two weeks and swapped to a 190lph fuel pump and noticed no difference...

If your planning on getting high in the revs "around town"...upgrade that fuel pump...

Stock pump was 88LPH untill 1989 and 95LPH there after (MAF used 95LPH). And, no the stock pump is not even suffiecient for a stock engine. So go with one big enough to supply all the mods you have planned (not just what you will do next) I would say go 190LPH just to be sure you will not regret it later.

Well they make the 190 and 255lph...those seem to be the most "popular" sizes for modded stangs...

They make much bigger fuel pumps than the 255lph though

Yeah, but for the $200 you get all new lines, new bracket....everything is new - no splicing wiring and stuff.

155lph will be plenty for your mods. Everyone is suggesting a 190lph, because they are the most popular for modded mustangs, and will support a lot of hp with out hurting you with your current setup. I am running a 190lph pump in my 400hp 331 with no problems, so I say a 155lph will be more then enough. You can also check out this analyzer, it might get you close.

Edit: I guess I should say, if you are going to go through all the work to put a fuel pump in, you might as well go with a 190lph, you will never have to worrie about it again, and it will support all you can throw at it, but if you can get a 155lph for cheap, it will be enough.

I dont' know how cheap you can get that 155lph but I got my Walbro 190lph fuel pump for $90 bucks from www.50resto.com ...just a FYI...

I can't even hear the pump at all...quiet as a stock one should be...

Good Luck w/ it...

Just curious...

At what point does a 155 L/hr pump start to fall behind?

The place I bought mine from said that the 155 pump is good 350-375 naturally aspirated HP... and then it's completley maxed...

That sound right?

Go ahead and get a 255. That way it'll already be there for later mods. Check around u should be able to get one for a little more than $100 bucks just about anywhere. I think I paid Like $109 mine
