Capri XR2 fuel pump

[TominMO]

I just noticed on Rock Auto that the Capri XR2 fuel pump is the same one used on the Festy! And a lot of other cars as well. I'm guessing that since XR2 stock boost is only about 6? pounds, a fuel pump for a non-boost application is good enough. But if you have some serious boost, what fuel pumps are best to look at getting? And are easiest to stick in the tank with minimal work?

Most people use walbros. I forget what I got but its supposed to be superior/quieter than a walbro.

As far as other factory pumps? I wouldn't bother. A used one could die and a new one will be more expensive and flow less than a walbro or other aftermarket.

[TominMO]

Walbros flow about 60 PSI IIRC. How high can you go with boost @60PSI?

Also, how long do the stock Denso pumps typically last for an EFI Festy or Aspire, in either years or miles?

[bhazard]

60 psi isnt a measure of flow

Is rocketman recommending a fuel pump upgrade for his B6T ECUs? That should tell you something.

The pump should support more than people think.

I know a remap is different than using a FMU, BUT if you do bigger injectors AND the FMU with a stock pump and lowered base pressure, you should be able to stay safe.

I am going (very slowly on my build) with a Crown Vic pump. They are cheap new, and flow enough for a V8 making gobs of torque. Maybe 2 of them for "serious" boost on the cheap. Would be under $40 plus ship from rockauto.

as far as i know rocketman dose not recommend a upgraded pump and has pushed 19 psi with one of his chips .
i did not know the festiva and xr2 pumps were the same i knew the non turbo and xr2 pump was the same.

60 psi isnt a measure of flow

OK then, 255 lph (liters/hour?).

depends on its history.

One used everyday and filled-up completely at each refuel went 235,000 miles.
I bet if I had not let it set for 2 yrs it would be running today.

Picked up a festy with 85k miles on it, but it had sat for a long time and I got it for parts and the engine so it sate longer and the pump died one time while trying to give the motor a good run.

I still wonder if a good cleaning might bring some of these pumps back from the dead.

For a B6T running a stock or hybrid turbo you don't need a fuel pump upgrade. The N/A and XR2 pumps are the same. I will always recommend a good fuel pump re-wire though to ensure it gets proper power

How would one go about a fuel pump re-wire?

We have our own 190, 255, & 340lph fuel pumps that are a direct replacement for the festiva.

Mine has 332K+ miles on the original pump.

That is comforting to know! Lately I have had a brief and hopefully gone issue w/my Aspire, and one of the suggestions was bad fuel pump. I ordered one to throw in the trunk for the trip to Madness.

Google "Fuel Pump Re-Wire" there's some pretty good instructions for the DSM cars. Basically you create a new fused circuit, using heavier gauge wire directly to the pump. Well, you put a relay right near the pump, and use the original power wire to trigger the relay. The stock wire is pretty small and has a large voltage drop by the time it gets to the pump - by running a heavier gauge wire you effectively increase the power available to the pump. I will be doing one soon on my new Capri, I'll make a writeup out of it.
