Will my fuel pump fit

  • Sponsors (?)


I 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 :shrug:

Side Note: The OEM pump is only 88L/Hr
 
The 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 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 else

But I was told that the 255 is meant for if your making higher hp or if you have a turbocharger or supercharger

In that’s case should I just find a 80lph

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.

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 199

I 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

I'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.
 
So I used the stock hanger to install a 190lph Walbro pump and then a few years later put a 255 lph Walbro pump in the same hanger with zero issues. This was over 10 years ago so buyer beware. I would suggest that you check the passenger side fuel rail and see if it has the stock fuel pressure regulator (FPR) on it or an adjustable one. If it is not an adjustable FPR you should seriously consider installing a good one. I have an Aeromotive FPR on mine and it holds pressure steady as a rock even at idle.

With regards to waiting to put a big pump on a car until you have the mods engine wise that demand it I would say it all depends on how you look at things. If you are putting anything other than a stock pump in the tank the wise move is to get an adjustable FPR as the stock one was not meant for anything other than what it was designed or selected to work with. Will a stock FPR work with a larger pump? I would say that too is subjective to your definition of work. I would say that at idle a stock 5.0 is going to burn just as much gas as a built 5.0 even with a power adder so that is the point at which most fuel will be returned to the tank.
 
It's tough to go wrong if you stick with the Walbro pumps.

The [Entex or Antec or whatever] and some of the others that the parts stores sell aren't worth the cardboard they're boxed in.

Almost every parts store can get Walbro even if they don't stock them as a brand.
