Oil pan is on and ready to go. I got my Christmas present today so things will progress quickly towards completion. Unfortunately, unrelated to the car I have suffered a hand injury so it is making work slow going.
I installed the flex fuel sensor to the factory supply line. However, the factory supply line is now the return.

The Squash Double Pumper will use 2x Walbro 400 units so I will be reporting back on its operation soon. Since I already had 1x Walbro 400 I had them supply me with the second unit. Outlet is -8 and return is -6.

Almost done with getting the motor back together and then I can focus on the Squash Double pumper install. I will have to order a few lines from Summit, but I hope to have it going by next weekend.

Better safe than sorry...

Subscribed, reading your thread makes me feel a bit better with all the time my car spends getting worked on. lol
GL I cant wait to see some results, are you planning to do a 93 map and an E85 map?

I was able to get the fuel filter installed today. There was a nice spot under the car in the rear, but because of my 1/2" SS hardline I could get it plumbed with AN lines. I purchased this inexpensive highflow filter/bracket/fittings from SquashPerformance along with my double pumper. I should have the remaining fitting tomorrow to plumb the rest of the car.

UPDATE:
I was able to trim and paint the fuel filter and fpr regulator brackets.


I ran all the extra wires through the firewall for the Flex Fuel Sensor, Air Temp Sensors (before/after) intercooler, and two switch ground leads for future use. It is hard to see from the picture inside the car, but the hole goes through two pieces of sheet metal and I have a rubber grommet with black silicone on the firewall side. I will squeeze some silicone into the wires for final water seal.


Finally, I am wiring up to the E85 gauge that also sends the 0-5v output to the Haltech.

UPDATE:
I finished installing the Autometer single gauge pod for the steering column. The gauge is nice because it shows me ethanol content, but also converts the flex fuel sensor output to a 0-5v analogue signal for the Haltech.




I was able to install the Squash double pumper with 2x Walbro 400's. I shipped my siphon and pump to Squash and they shipped back this nice unit. I also ordered from them some relays for the pumps.


I next had to shorten the crossover tube 3" for the saddle tank due to the location of the fitting on the Squash unit. I removed the crossover tube by undoing each end and wiggling around. The crossover tube snapped out of the two clips and it pulled right out. I mocked it up on my bench and held with some clamps. Holding the passenger side I slid the drivers' side over 3". I applied heat with a heat gun and the vinyl tube held its shape. I then snaked it back through and installed.


I then connected the fuel lines from the hard line to the Squash unit. The factory hardline is 5/16" so I purchased an efi fitting from 5/16" hardline to 3/8" line in a 90deg. I am using the factory hardline as the return. The one on the left is the factory 90deg connector. Interesting the the OEM pump housing is 3/8" going to a 5/16" hardline.




Finally, I got the relay wiring started and this is basically the last thing remaining before I start the car. The second pump will be controlled with the Haltech via switched ground to its relay.



I have the relay power wires running to the battery box in the back where it will be connected to 2x 30A fuses.
