Re: Warrens Conversion -Heater Hose Routing
Today I got the hoses from the fuel tank to the fuel pump plus the FI return connection to the tank all connected. ?I used 1/2 inch fuel line from the tank to the fuel pump and 5/16 fuel injection hose on the short return bit. ?I was also able to rotate the stainless coolant pipes to the engine bay, even getting the screwy spring clip around the pipes! I was also able to route the heater hoses through the firewall and zip tie it all together. Not the prettiest but it’ll do. Progress!
?
I was even able to get my tools cleaned and organized. ?Overall, a good day working on the conversion.

Re: Warrens Conversion -Heater Hose Routing
The fuel tank has been refreshed with new seals and hoses. Those plastic vent boxes under each fender have been thoroughly cleaned and a new grommet installed. I only need a couple small clamps to finish up.?

Re: Warrens Conversion -Heater Hose Routing
I was able to confirm that the nipple had seated on the passenger side. I almost dropped my phone taking this photo. Scary.?

Re: Warrens Conversion -Heater Hose Routing
I got the crossover pipe installed. I used silicone grease and the nipples slipped right in. The hard part was reaching in to do the job, especially the driver’s side.?

Re: Warrens Conversion -Heater Hose Routing
My fuel injectors came back from Mr. Injector. They look great and the test report is good. ?He pointed out that one of them needed a central o-ring replaced but that he did not stock those. So I decided to replace all of them but my local Subaru dealer wanted $11 each! ?I found them at subarupartsdeal.com for just over $4 each. They might arrive today. If so, I’ll install them this evening.?

It’s entirely possible that I caused this damage.?

Re: Warrens Conversion -Heater Hose Routing
Awesome - glad to hear it! I’ve been enjoying following along with your project as I work on mine in parallel.?
Cheers to this group and to continued forward progress!
Big thanks to Ian!? Thank you for the reference to the GoWesty illustration.? After seeing that illustration and watching the video several times I was able to reposition my front half coolant pipes and get the fuel tank mounted!? Yes!!
?
I still have to connect fuel lines, vapor lines, crossover tube, vapor tanks, and filler neck, but that’s all reasonably straightforward (even if it takes some Houdini moves to get there).
?
Thanks again!

Re: Warrens Conversion -Heater Hose Routing
Thank you Ian. I found that video helpful. ?I noticed that they show the pipes even at the front but mine are not even, possible offset by several inches, which may account for my fuel tank not fitting. This gives me a starting point.
?
New day, positive attitude, so I’m expecting success today.?

Re: Warrens Conversion -Heater Hose Routing
Ian,
thanks for that tip/link, I bot the pipes and held off installing them till I heard the resolution to your issues. Many thanks!

Re: Warrens Conversion -Heater Hose Routing
Warren.? I really appreciate your conversion writeup and want to support you in continuing that.
But....(you knew that was coming), you should not use the group as a leverage tool for contacting related vendors.
I'm against anything that feels like flaming of other folks, vendors, or anything on this group and would ask you to shy away from that in the future.
All the best,
Brent

Re: Warrens Conversion -Heater Hose Routing
I was able to route my heater hose through the opening in the frame with the coolant hoses. ?I got the radiator hoses connected, the heater hoses connected, and the front half buttoned up I hope. ?I’ll find out when I try to install the fuel tank later today.

EJ22 OBD-1: Strange Start Problem/Fuel Pressure Regulators
Thanks?for all your helpful comments.
I wish the 'connect the green test connectors together' had told me anything - I did this as a first step when I started this diagnosis - but there were no codes or non-normal behaviour. I suppose the transient supply voltage?drop from that burned?fuse/holder was not enough to trigger anything.
The pointer to the Standard Products PR260 2.5 Bar (36 psi) fuel pressure regulator was very helpful?- thanks Wayne!? That's the first one I've seen that actually calls out the pressure spec. I was stupid enough to believe?the claims on the ones I bought (to fit this non-turbo engine). Since injector flow rate goes as the square root of pressure, a 3.0 Bar FPR would give 10% extra fuel flow (vs. the 2.5 Bar spec). I would expect the ECU closed loop control to deal with this just fine at constant speed but might see some impact at acceleration (better acceleration, higher fuel use?; I don't really need/want either as this is a Frankenmotor). If I was wanting to find out more I could compare the two (but the FPR is hard to get to!). I could probably have stuck with the 3.0 Bar FPR just fine - the higher fuel pressure?might increase the risk of fuel leaks a little. I put the old Subaru unit back in and it seems good.
Now I have several new spare parts to store away under the seat! Thanks Again!

Re: EJ22 OBD-1: Strange Start Problem (Pt 4 - the finale)
For crank/no starts my go/to is to connect the two green test connectors and turn the key to ON. Solenoids, relays should be clicking and fuel pump cycling. If not I go to the two power feed fuses to my Subaru harness (battery and ignition power) Usually a test light suffices and I check before and after the fuses and the fuses themselves. Often said you should replace the fuses anyway even if they look good. A multimeter might have helped you more and you might have caught the intermittent fault. In hindsight,be sure? or reasonably sure of your diagnosis before ordering parts especially expensive ones. Oh well, you have a box full of spare parts if you need one now. Try diagnosing it when everything works but it won't fire. No injector pulse or spark. Replace cam and crank sensors not it. Then it's your ECU.

Re: EJ22 OBD-1: Fuel Pressure Regulators
Rockauto has a Standard Motor Products FPR (PR260) rated at 36 psi for the 94 2.2 NA.I got a Standard Motor Products? FPR for my 02 2.5 that worked well.

Re: EJ22 OBD-1: Fuel Pressure Regulators
Welcome to the modern age of auto repair. The parts are all crap, everything needs to be rechecked. The residual fuel problem is a check valve at the pump on the VW. another $5. As for the fuel pressure, monitor o2 sensor and fuel trims. The aftermarket will combine part numbers without any knowledge of what is going on. I recently replaced a fuel pump on 1990 GMC syclone, the catalogued pumps all would not support the turbo. Is there a drivability problem with the 43 psi? the o2 should compensate for that. If there was a symptom from the old regulator, maybe it's not the regulator. I would be ok with -15% trim at idle. If highway cruise is more than -10% and acceleration is still in the negative, injectors are an option.

As an addendum to my EJ22 Strange Start Problem debug, I had an issue finding correct and quality parts; perhaps someone has comments on the following?
I bought 2 new fuel pressure regulators (Herko and Beck Arnley brands) - I couldn't find any genuine Subaru units from any of the Subaru parts dealers. Both were supposedly correct for the 1994?Legacy EJ22 that my engine started life as? NOT! Both turned out to be 3.0 Bar (43 psi) units and measured fuel pressure (at Idle) was markedly higher than the original.? Research on this led me to see (in Haynes) that there are different specs for the non-turbo EJ22 ?(2.5 Bar = 36 psi) and turbo EJ22 (3.0 Bar = 43 psi) However all the online?parts listings I can find claim their units work across both engines; obviously incorrect.
I put the old Subaru original back in (it's marked as JECs A44-000R55) to recover the lower pressure
....Any ideas on where to get a 'correct' 2.5 Bar unit from? (Subaru parts dealers have a part # 22670AA050 but they list this for both non-turbo and turbo cars...). Also, how to be sure they really are 2.5 Bar units before installing and?measuring them?

Re: EJ22 OBD-1: Fuel Pressure Regulators
Small car sells one, mounts between the rail and the fuel filter. Gives you around 50 psi I think. Don’t the 2.2s have a rail mounted pressure regulator like my 2.5 does? When last I checked it was still available.?

I looked up the part you reinstalled and it came back as a fuel injector rail (A44-000R55). Subarupartsdeal shows the other part (22670AA050) as discontinued but even then they do not mention anything about the pressure. ?You may have to go to a parts yard and find a used one.?
