in the process of getting a 02 5.3, already have a new blazer tank so what inline fuel pump should i get?

I used a walbro 255 inline on my 6.0..no issues so far. If your using a new blazer tank why not use a in tank pump?

I also used walbro with my LS2 and vette filter/reg combo. So far so good. Once I relocate fuel tank to under bed Ill install in tank pump though. Kill the noise and help pump last longer..

really its easier to plumb it inline, than to cut up and weld in a flange for the in tank pump,unless there is an easier way..

Inline pump, vette filter reg is def easier but if I had a new tank to start out with I would have went in tank just to clean it up install and keep the pump cool..noise isnt much of a problem on mine...remember you'll need 3 barb sending unit on your tank..one for suction ..one for return..and one for tank vent.

Inline pumps are plenty fine for most of what we see folks building on here. The 255's will fuel LS motors up to around 500hp, depending on a few factors.

You get to a certain point when the smaller single pumps won't cut it, you can run twin pumps or one of the "upmarket" inline options. The intank will always have an advantage in terms of supply and cooling, yet when you get REAL big, many of the fuel systems are inline (or high pressure compound fuel systems). The curve kinda goes like this:

small inline->(small in tank)->twin inline->(twin intank)->Large intank*uncommon*->Large Inline->Race /Compound Inline->HP Mechanical

I don't know why I bothered typing that last part but I did so now you just read it.

thanks guys, i`m just wanting a dependable system one of the reasons i was thinking inline is in case i ever needed to change it.

I've got about 7-8000 miles on my walbro 255 vette filter reg setup...no issues so far, very reliable and seems to be the go to setup for most people
