well i am getting to the point to were i'm ready to turn up the boost and i've made the decision to go with e85. it's $1 cheaper than 93. I've seen it floating around $2.40-$2.55 a gallon.

my truck has the return style fuel system with the rail mounted regulator and the walbro 255 i had in there now would not keep up with the demands at 60psi

i bought the walbro 450 off ebay and got it installed tonight. all of 30 mins


Walbro 450 vs. 255


a few crimps



and it's in

 

fuel pressure is 56-58 at idle, with the 255 it was 50psi

tomorrow ill get some corn in the tank and start adjusting the tune. also need to make a hole for the filler neck since the new bed has a shaved gas tank door

 

Im super jealous man. Id be all over e85 if I could get it local. Best of luck!

 

Stock regulator? I'm doing the same swap soon (return style with rail regulator) and would like to know what else you bought to make it work. Thanks

 

yup, i think i replaced the regulator 30k miles ago, but other than the walbro 450 everything is stock with the fuel system and 60# injectors

 

Cool. You use a hotwire kit for this or the 255 install? If so, where'd you get it?

 

stock wiring

 

Sweet

 

there's only one pump in my town, and the other one is 20 miles away. it shouldn't really be a problem tho since i dont drive far from home very often

i will have to plan my trips accordingly

yup, if something needs to be upgraded i will, but just wondering if this can be used as a replacement for the 255 since it's rated for e85 and flows a lot more than it.

the price is very close too, i got this pump off eBay for 130$ shipped

 

You need to upgrade the wiring ASAP. Not smart with the 450 given its current demands. Also 60 lb injectors are too small for e85. I already maxed out the single 450 at 12 psi and 81% IDC on 114 lb/hr injectors. I was experimenting with E50 until my trans blew up.
