What inline fuel pumps are yaul using for TBI. The gas tank for the blazer is leaking and I have allready have a good fuel cell. Would the E2000 work for this application?
 
Thats what im running on the tbi swap i put on my 78 F150. You may need some baffles in the tank or a sump or surge tank to keep it from dying when youre crawling though
 
fuck the 4.3 tbi

Sorry had to....

yeha I am 99% sure the pressure spec is identical to the sbc
 
Why do you have such harsh feelings twoard the 4.3 TBI?
 
anything running around 15psi is good, the E2000 sux if it suxs air it wont prime itself. I used a holley pump I had laying around, holley blue pump I think, worked great.

nah just pissing on you, you have been *f'ing* everything from The Bible to Fox news lately, I figured it was just fitting
 
I put more faith in the chevy 4.3 than I would ever put in the bible or Fox news.
 
I've got an E-2000 running on a 1 jet TBI. Works well but noisy so DON'T mount it on the firewall.

Also fyi, for fuel filter I used one from chevy trucks (one that they use in every chevy truck), got some fittings to make it work, seems to be good!
 
i have 4.3 tbi in my blazer and love it to death if i build a buggy thats whats going in it it has good power and lighter then 350 and can be built for high rpm's pertty cheap

So If it only needs 15 PSI then why are people using the e2000? Isn't it like 50PSI?

not sure, I had to do some research and all the tbi guru guys said 15-18psi is ideal, anymore and it ruins the pressure regulator in the tbi unit. Im not an expert, this is just what I was told on pirate after getiing flamed for my lack of knowledge, but I checked the pressure of the holley pump and it was dead on 15psi, loud as hell, but ran great. Also make sure you run a return line to the cell. Also try placing the pickup in the back corner and slightly elevating the front of the cell. Or you can get those screen pickup deals, they work pretty good
 
I just did a little google search, vortec motors with Multi port injection need to run higher pressures around 55-65 so E2000 would be good for them, but TBI seems to be around 10-15psi
 
Thanks man....I appreciate the info
