I’m buying a fuel tank kit for my 1990 foxbody and it comes with a 255lph fuel pump which is to big for my foxbodyand comes with a bracket can I buy a 190lph fuel pump and use the same bracket from the 255lph
I don’t have a 255 rn in my car. It has been sitting for 15 years and the old fuel tank was all rusted so I had to buy a kit or buy everything separately but saw it was cheaper to buy the kit I was looking at and buy everything elseI can't think of a single reason why you would want to swap the 255L for the 190L. Your car has a return-style fuel system. This forum is [filled] with dudes running 255L pumps that don't necessarily need them.
It just leaves you more room to add power
Side Note: The OEM pump is only 88L/Hr
In that’s case should I just find a 80lph
No I do not already have the 255 tbh when I dropped the tank the pump got Thown away with the tank so I forgot to look at what size it was but my uncle that helped build the car many years ago said he doesn’t remember upgrading to the 255But if one already possesses the 255L...
Thank you but my main question was will the 190 fit in a 255 bracket I’m thinking of buying a fuel tank kit and it comes with a 255 and was planning on just buying a 190 pump but I was wondering if I can save me money and just use the 255 bracket for a 199The issue with too large of a pump is the fuel lines. If you supply too much fuel that the engine doesnt need, you create additional restriction that manifests itself in the form of higher pressure at the rail. Now, one can simply adjust a fuel pressure regulator down, but if you dont have one, then you are kinda stuck.
This is more of an issue if sticking a 255 hi flow pump on a stock 5.0 engine and likely not as noticable on an H/C/I car.
WHen i went from the stock 88lph to a 190lph on my stock engine, i had to adjust the regulator down from the previous setting as far as it could go and it still a psi or so too high. Hopefully the latest HP bump takes care of that.
Will be different for everyone, but I tend to suggest to size your pump appropriately. A stockish cruiser that will never get modded does not need a 255 pump.
I wouldn't put a 88 back in.
What is your future with this car? I'd do 110lph for a stocker, and 150lph for something that might be stock head with some bolts ons or a different cam or exhaust and such.
You can certainly go bigger, but I would suggest sizing appropriately vs just slapping the biggest one you can find in there.
I do think it does already have some mods I can show a pic but I’m not 100% on all he didI wouldn't put a 88 back in.

And I do know it has nitrous but not set up fullyI do think it does already have some mods I can show a pic but I’m not 100% on all he did
But I plan on keeping it how it is for awhile
Ok thxI'd do a 150 if those are stock heads and If there are aluminum heads down there i'd do a 190
I cannot answer if the 255 hanger will work as would need to see it. For the most part the fuel pump hangers are the same and the pump just interchanges. So if the current hanger is a stock type hanger then it would work.
