Electri Lift pump for 90cc?

[asmith]

I wondered that. The other thing is that since it’s 1/8 npt, most of those fittings have tiny holes through them. I drilled all my fittings out to about as large as I could. It’s not like it’s a high pressure system needing heavy wall fittings. Swagelok stuff is notorious for that. Most of their fittings are rated for 2-3k psi.

I was thinking about if you could drill them out or not because CLB brought up the small fitting size in my thread about my fuel filter light kicking on on hills.

How much bigger would you say you made the holes? I assume you used a drill press?

I don’t remember for sure. I used a lathe because I had one. I used swagelok compression on the inlet side. It’s 3/8 tube to 1/8 npt. I’m sure I bored it through to at least 1/4”. Maybe a little bigger. I don’t have a fitting handy to measure but 0.1 wall thickness should be more than sufficient if you don’t go gorilla on it and if you are using brass I’d add a little more margin not for pressure but just mechanical strength to not have it break off from vibration.

Cool! What is it?

FYI the pressure gauge on your filter header is reading pre-filter pressure only, it won't tell you what the pressure is at the IP inlet.

This is not true, it reads post filter

@gerlbaum
Ya got specs on the little filter?
How big is it, flow, part #??
Thanx cb

Sure do, Parker PS120. I was wrong, the micron rating is 200 to 260 - technically a "fuel strainer". You can unscrew the plastic and clean it out if need be and the strainer thing can be replaced.

Edit: Flow Rate of 120 GPH, I'd say it holds a couple pints...maybe ~2 pints.

Really? I thought the fuel enters the header unfiltered and the Schrader valve is tapped right into the inlet passage?

If it is post-filter then the return port is actually filtering the air first before its returned, which seems odd they would design it that way but then again...they also took away perfectly useful gauges for dummy gauges.

One other thing I like about it, it's a big enough bowl to act like a surge tank you use to see on gas carb'd cars. If you hit a turn ******* a low tank and suck air up your intake this would allow you to still be pulling diesel since our tanks aren't baffled.

Here are the specs for the 700 series brushless pump/filter.

@gerlbaum was just trying to keep some crud from the pump tanks kinda old and dirty, @The_Josh_Bear carter 4070 pump. Also I thought that is where fuel pressure is tested? I could move it over to the other port then is there where pressure is after filter?

Let me rephrase, the vacuum sensor port reads outlet pressure, the others are inlet side

Ok cool that's what I thought!
