Bumping an old thread here but I installed a soft start on my 2.5 ton AC unit. My house is mostly gas with the AC and 3 kids tvs, gaming systems, 2 fridges and a deep freezer being most of my electrical load. I use to run a 803 and downsized to a 802. Needless to say when the AC would cycle on...

Aftermarket fuel/water separators lacks the drain hose on the bottom which can make a mess inside your unit when you do drain water. With two needle valves, a cap, some fuel line and clamps you can rig one together. You'll need two 1/4in OD X 1/8in MIP angle needle valves and a 1/4in OD...

*update* So I replaced the IP that had the leak and shimmed them as mentioned in this thread. I also suspected that there was some bad fuel so I kinda threw everything I had at the machine. I replaced the fuel and separator filters, did an oil change and a few upgrades. She is running strong...

I confirmed that it was leaking from the body of the IP. Once I had a bead of weld applied it stopped leaking. Just to be safe I ordered a new one. When it comes to installing the IP I always only removed one at a time and was sure to move the adjustment pin far left. I've never had to force...

It definitely makes sense and I've noticed the same. I'm using crimp clamps and when I pinch the clamp it causes a portion to become raised. When I install the IP I turn the hose to move the raised portion out of the way.

Just from reading the TM it is made to sound that finding the correct shim thickness is imperative

Perfect, I've also noticed that the set runs smoother turning them that way. Thanks again Ray.

I should have asked but I didn't think about it until now. You can hit a pushrod tube going in both directions. Did you turn the IP clockwise or counterclockwise to hit the pushrod tube?

Thanks for clearing that up, I was concerned that it would be a pain in the butt to get the shim thickness correct

I was assuming that because you are starting with new parts you would have to reshim the IP since the tolerances have changed.

$315 US a piece plus me having to re-time two brand new pumps.

Post a picture of your pieces and I'll number them for you

Yeah I got two delphi's. I guess tonight on the midnight shift I'm going to starts crawling the web to find a parts supplier for these guys.

I everything stamped on the housings match exactly. The LP part number, a TPF# and the delphi-II markings are all the same.

LOL look at my thread right next to yours, I'm working on the same part and I can definitely tell you how to put it back together. My problem is I have two IP's that have different amounts of rings in them so I don't know how many actually go into a IP.

The plot thickens. So I decided to pull the other IP and disassemble it to compare because prior to this I've only disassembled the leaking IP. I've laid out the two, so the IP on the right is the untouched one. It has two extra parts that the other one does not. I've also attach a pic of...

The fuel leak was around the IP inlet fitting where the low pressure hose connects. I had a guy run a bead of weld around it and it stopped. I'll get pics up in a few days. Once I got it all back together I gave it a test run to check for leaks and it ran fine for a few minutes then sputtered...

As the title says I have an injector pump leaking fuel. I've ripped the whole thing apart, cleaned it and replaced the o-ring on the high pressure side. I double checked the fuel line and when I put in all back together today I replaced the hose clamp with a new crimp clamp on the low pressure...

Good advice, I didn't mean to make it sound like the unit is going to die if he continues to run it the way he is. One of the biggest factors for me was the fuel burn rates. 803 @ 1GPH vs the 802 @ .5GPH. I figured worst case scenario for me in PA would be a week straight I'd have to run...

Not that it matters but what's the 803 read when the ac is running? Have a soft start put in your ac's outdoor unit and I'd be willing to bet a 802 will run your house all day with no issues. It's been said more times than I can count that a 803 is a lot of machine. If I was smart I would...
