I finally got some $$ together and wanna make my setup more efficient and reliable.

When I was getting tuned, as we kept bumping my boost up, I started leaning out on top. I am running pump gas, in Canada, we use 94 octane with 10% Ethanol. I was told I was bleeding pressure. The tuner managed to mess with my fuel map to make my map safe however me being me -- I need to get this fuel issue under wraps. A lot of threads ive read are more geared for E85. I have read everywhere that single 255 on pump should be able to get me over 500whp no problems. I've also read that maybe the cradle with fuel filter in it is clogged.

Heres what I think my options are at this point

1. Get a new cradle -- theyre 140$$, it preventative maintenance anyways. Run my current Walbro 255 I have in there now since its only a year old.
2. Get a new cradle and also do the relief valve mod which was recommended to me. My issue with this option is -- I dunno how RELIABLE this mod is to the fuel pump.
3. I could always do Buschur DP and run hobb switch however I think that's really overkill lol.
4. < INSERT ANOTHER SUGGESTION >

Before I start adding things to a shopping cart, wanted opinions. Again only running pump gas. Don't imagine E85 will come to my location anytime soon. Looking for a nice reliable setup. Btw I am also ordering a in cabin fuel pressure gauge as well

Thanks in advance to those who can give some constructive feedback

You need to punch the relief valve. The pump will be fine.

How much boost are you running? The walbro could very well be done depending on boost and the HP you're making. Mine was running out up top on 91 when I was tuning it myself and making about 420whp at 27psi..

 

29 psi I think I'm at.
Was ur issue on e85 or pump?
Relief valve mod reliable ?
Thanks for the reply

 

On 91 octane pump gas. At only 27psi, and I had the relief valve punched.. Punching the relief is plenty reliable. It may shorten the pumps life, but they're less than $100, so it's not a big deal.

 

Cool, ill go that route. Thanks again for your help on this!
