Regulator backwards?

Regulator backwards?

Don't think so, but that's something I'll be checking. Going to get the shifter mounted today and clean I think. I need to have some space on the workbench to check my wiring diagrams too

And when i saw wiring diagrams I mean my crude drawings of wires on junk mail

 

[SenorNoob]

That's how you know you're good. When you wire a whole vehicle with junk mail notes... LOL

Did somebody say "wires"???

 

[SenorNoob]

Looks like fun. I'm jealous. LOL

So the regulator was the right way, but the wrong ports - I had the input into the wrong fitting. Engine is getting fuel now, but only about 10psi at the rail. Not starting.

Have a crazy busy week this week, so won't be able to get to it much done this week. good time to take a step away and come back refreshed hopefully. Did get my shifter in, smooth as butter

I think my regulator was shot, or at least isn't working correctly. Internet likes a Wix, giving that a try. Kept hearing @bobbywalter in my head saying he doesn't like them

If I remember right you got one of the AN fitting versions of the filter regulator? We use the NAPA 3737 which holds reasonable pressure as of the last few months. There for a while when WIX sold out (you won't find that filter/regulator made by WIX anymore) NAPA and everyone got them from Lingenfilter or however you spell it and they were garbage if you put any reasonable pump to them, we would get them putting out like 80psi when it should be 58psi... and some that wouldn't even return anything. If you use that filter/regulator near the engine it should supply enough fuel for a stockish engine, we use them at work through around 400hp.

I got fittings to convert the wix to AN with it. The speedway one I got that was crap had the AN fittings. Everything will be here Wed and we'll see how it goes. My crank and TPS sensors and fuel pump are reading good, so I think I borked the regulator up when I had the supply/return fittings switched.

The supply and return on those filters are just one is on the inside of the filter the other on the outside, the supply is on the outside the filter media (big pleated jobber) and the out and return are on the inside, getting them backwards wouldn't hurt them. The problem is the ones they made for a while had like a 1/8" outlet port or smaller that just couldn't keep up with a pump capable of feeding a healthy engine...

Very likely it just sucked too. Had 0 psi before i saw that and then 10 psi after. If i hadnt run the braided line I would have just bypassed it with one of the cheapo inline filters i had for the 4.0, but oh well for now

Fun times doing some diagnostic stuff yesterday. Got a new regulator on it, still 10 psi on the fuel rail. Verified 12 volts at the pump, time to start checking everything. Checked my connections for the injectors and coils, and cranked it on starting fluid, and it started up. Feel pretty good that it's a fuel delivery issue. No kinks in the lines, everything looks pretty good.

Checked regulator output, 10 psi, 10 psi at the feed right after the pump. Opened the fuel cell to make sure that the pickup is fully immersed, it is, but when the pump is running I'm getting a good amount of fuel coming back down from the pump area. Feels like the pickup is loose or something along those lines, that'll be the next thing to check.

Soooo close and so far away. wife was NOT happy with me making her run it while i was spraying into the intake, so I'll have that moment at least.
