Diy fuel system questions.

[littleredstroker]

Doing a home built job, using a 5/8 pickup tube, I was going drill the metal cap next to the stock pickup tube for the location but I'm wondering if I need to put anything on the bottom of the tube screen or anything, and then how far up off the bottom should I cut the tube, 1/4-1/2 inch ?

Normally when do them I'll set them an 1/8th inch off the bottom, and then v-notch the end so it can still pull fuel if it sucks down to the bottom of the tank.

Ok cool. Never thought of that, but that's what I was worried about was sucking closed .

why not sump it?

I have the stuff to do a pickup tube already, I guess that's the only reason, hope that's ok.


Can I run filters between the tank and the pump(s) I'm not real smart about these pumps.. I know pumps push good but suck bad. Would sucking through 2 filters ( 2 micron final) be too much ?

water separator before the pump ...the 2 micron filter between pump and injectors.. that way if your pump blows to chit the pieces will not make it to the injectors..

Got it. Ok And what size line is a minimum from last filter to head ? 3/8 be ok ?

stock pump? 3/8 should be ok....

Will be dual stockers for 250/200% when I'm done

I would at the very least go 5/8 to the filter to take advantage of the pick up tube....my set up is 5/8 all the way to the heads and 3/8 for the ride back..maybe a little over done but my fuel lab wont need to work so hard...ill know for sure in a couple weeks when I finally get her running..

I made the kit for him and when I bought it I based everything off of how the irate kit is.

 

[littleredstroker]

It is (correct me if I'm wrong Chris) 5/8 to the first filter

Mine, is 5/8 from the tank to the pre-filter. 3/8 to both pumps and to the second filter. 5/8 to the heads. I use the stock feed line for a return line. I have it plumbed in the tank to dump as far back from the pickup as possible. I made the draw straw the same length as the original and I modified the pickup tube to fit on the 5/8 straw.

 

[chris89]

What he has is 1/2" from the second filter to the y fitting the 3/8 to the heads.

This is hw I did mine, used the 5/16 return line, works just fine. Dual stock pumps, feeding stock injectors. I'm going to run the same setup with the bigger injectors.

How many gph is the stock pump good for?

Buddy had a walbro pump laying on the shelf he got me a deal on. Looks like its 225 lph which is around 60gph @60psi. Would that work ok with a stocker or do they need to flow the same

Al, Im thinking using the stock pump, stock wiring, just splicing into them and making the plug long enough to reach the pump location.
Then running a separate relay for the walbro, no connector just two studs (-.+)

I have a left over relay from my AIH delete, can I use this for the pump relay

oi would not do it that way.
way to much draw amperage wise for oem wires.
if I follow what you are doing.
you need to run a separate line to the walbro.
use the relay from the stocker. to turn walbro (or second pump) on and off.

but I would keep the pumps the same ie.. replace the stocker with one walbro...run two stocks or two walbros.

dennis sells a good wire harness and relay for that sort of thing.

 

[littleredstroker]

Dennis who??

So then a hot wire from battery to relay, relay to pump (s) that is actuated by stock fuel pump wires? Yes?
