need help with my lsa build 1978 k5 blazer

[herrerabryan84]

so I'm having a hard time finding anyone who has done an lsa swap on a k5 blazer , little info on my build , 78 2wd blazer with ls2 and 4l80 , lsa supercharger , my concern is my fuel system , I got an 87 suburban fuel tank made for the efi , now I'm going e85 so I bought dual aeromotive 340 fuel pumps , the issue I'm having is using the stock sending unit in the tank , it doesn't fit that well with my dual pumps , I had to fit them both snug but I feel that the stock sending unit isn't just not adequate , I don't want to keep wasting money on buying new parts , so if anyone has done a similar build with dual pumps , how did you guys go about it ? any info helps

Welcome to CK5 @herrerabryan84

I knew a guy in Los Angeles area with 2x Blazer, you wouldn't be/been a fuel pump dispensing tech ?

With that kind a of performance, needing high volume of fuel delivery might be time to step up to a fuel cell. I know Nascar is using e85, before the cup cars went EFI they had belt driven mechanical pumps to feed those engines. Not sure what is used today.
