adding intake fuel pump in blazer tank - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Custom 68 · 06-15-2005, 09:34 AM

hey all I have a new plastic fuel tank I did the conversion with. is there anyway to add an intank pump in this? I have added fuel injection and am afraid I may not get all the presure/flow I need with just an inline one.
Thanks
Dave

inline (electric ) not enough pressure or mechanical pump ? i know barry grant got some fuel pumps that would suck a golf ball thur a garden hose or pump fuel like crazy
do you have a fuel regulator ?

sorry about the confusion yes it is an electric inline, it is back at the tank I have dropped in a 2001 5.3 motor (basically ls1) that require about 58 psi at the fuel rails, currently it looks like it is around 48 or so psi with my current pump, I am not sure the specs but thought it was capable of all the pressure I needed.
sounds like what I need is possible with just a good external pump.

Dave-
There are some very good in-line electric pumps out there for what you need. The two main reasons for in the tank pumps is that it keeps them cooler and they can push the fuel alot easier from inside the tank plus they run quieter in the tank. But you can have a very dependable,quiet, and effective in-line pump for your set-up. Run the pump through a relay and you be fine.

I have a 150 PSI @ 43gph that I have no intention of using anymore. I paid 160 for it + shipping new last year, and never installed it. Its probally a pretty noisy pump though. You can have it for 100 + shipping (probally be around 15 - 20 for shipping from Canada)

Another option is to get a sending unit from a burb or blazer that has the in-tank fuel pump stuff. Only issue is that if you do not have baffles, it will suck air when you take corners, stop or accelerate hard etc and stall your engine out.
