Thread: what FPR to run and walbro fuel pump ?

Are you haveing problems with yours Mr specV? Are you saying the bottom one is stock?

Got my pump in today everything is good. Car is running super rich without safc2 so Im going to lean it out some with the safc2, Im running 10.00-10.50 all the way through to redline. Fuel pressure is around 36 psi with vacuum connected. Glad that I finally have the fuel issue worked out. I got a local shop that is gonna let me do unlimited pulls on their dyno for a 100 bucks so I can see a log on my AF all the way to redline and get it running perfect.

So fuel is rich even above 10 psi? That's great news.

yeap, got scared when I got it back home, the car just died for no reason, I poped open the fuel tank and the wire harness to the fuel pump had come loose, I wish it clipped on or something, I don't wanna be going down the road wide open and it come loose that wouldn't be good at all.

the top one in my picture is stock lol. no problems here i have had a walbro in my car for 4 years. but you can see that the walbro is a good 2/3 the size of the stocker with out the sock that it fits in.

look @ what i got

^Wow. I'm glad I searched this. So where can I get a good 342/high pressure 91-94 Walbro 255lph pump?





^B13 and B14 have different part #'s?

Wow, I can't believe Ben hasn't replied to this yet. I'll see if GregV has the pump.

I can get whatever pump you need. YEs the pumps and install kits are different between B13 and B14.

255 (nonHP) are good for below 400HP, 255HP pumps should ONLY be used for high horsepower cars. They will actually overwhelm the system and can make the car run poorly. Don't be afraid to use a 255 (nonHP) if you're only making 300 something HP.

- I should only be making around 240-260WHP on my N/A VE. What pump do you suggest for me?

190lph walboro. I think I got a spare.
