If you’re not worried about keeping original a filter like this would work. Just run a 1/4” hose down to the return line. this is a NAPA 3054 filter

This is a picture from the work shop manual. The second picture is a screen grab from a posting on rebuilding an R series pump. I had time to dig thru some boxes today and found the restrictor fitting from R1358. The third and fourth picture show the restrictor fitting. A #57 (.043) drill bit just fits snuggly.

I don’t have a fitting that I can get to to measure the restriction. Hopefully someone else here does

Did you still have the original fittings. I believe there is a restrictor in the fitting.

Mark There are 3 tests you will want to do. pressure, volume and inlet vacuum They are outlined in the Avanti workshop manual. New filter? There must be some reason the return line was capped off???

Mark The R1 and R2 pumps are a little larger in diameter for more volume and have a stronger diaphragm spring for higher pressure. The fuel pump on top is the standard 61-64 3155S pump 3 1/2 to 5 1/2 psi The second pump is an R1 3509S pump 5-7 psi The third pump is an R2 3508S pump 5-7 psi

Good to hear you got the Avanti running. Yes check the switch adjustment. Steve

Greg The starter cut out switch and neutral safety switch are the same thing. The starter cut out switch is mounted on the side of the transmission. Look in the transmission section for adjustment info. Try moving the shift lever from park to neutral while you have the key in the start position—- foot on the brake pedal. Follow the positive battery cable from the battery, it will connect to the magnetic switch (solenoid)

Nelson The Avanti rear brakes are self centering not the more common self energizing design. The front shoe does more of the braking when rotating forward. This is why the longer lining goes to the front and is called the forward shoe and the shorter lining goes to the rear and is called the reverse shoe. On the self energizing design the shorter lining ( primary ) goes on the front and the longer (secondary ) lining goes on the rear. The secondary lining does most of the braking. The forward shoe/lining wants to rotate with the drum but is stopped by the solid anchor at the bottom this will cause the bottom to wear faster than the top. It is common for the shoes to be installed with the short lining in the front ( like they would be for self energizing brakes ) this will cause the front lining to wear even faster. Steve

Rick There is a space. It looks like a 1/16” or so—1.5 to 2mm. I haven’t noticed any rattling, clicking or knocking. If needed an anti rattle clip from a more modern disc brake might be modified to fit under the retainer. Steve

Yes brake hose bracket

False. It is on the #4 cap.

#3 The exhaust manifold. The air injected into the exhaust supply's oxygen so unburned fuel can be burned in the exhaust.

The bracket on the engine.
