    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    Hey everyone, I ohmed the new pump and found it had resistance in the 1000 to 3000 ohm range. The old failing pump as well as a 2nd new replacement were both sub 50 ohm. I installed the 2nd new pump, and it's now working perfectly. Holley is taking the 1st new pump back under warranty. Thanks...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    The PO put in one of the kits. I'm just replacing the pump under the assumption it was the pump that was the problem...that it just wore out. We know what happens when you assume, though. I've now ordered a second new Blue pump to see if it works any differently...different resistance, etc...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    I was going to check that, but the voltage at the pump is 11.8V. I connected a charger up to the battery and rechecked and no change. Haven't checked with the pump running...only two hands and can't get it to run reliably. The instructions indicate a 7.5amp fuse, which seems pretty small...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    It's below the tank. The previous Holley Blue ran for years without issue...just replacing it with a new one that is the same, but even with power direct from battery (using big wires), it won't run reliably. Seems to like to run dry, but once I've run the engine, it won't turn on the next time...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    Yeah, I was thinking maybe it was dead-heading and shutting off, but the pump has an integrated bypass and has never done this before...pump normally just runs if the key and safety switch are "on". When I get it pumping again, I may do as you suggest. I also bought an analog fuel pressure gage...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    I assume whoever did the swap ran into some limiter, or was just trying to get it done. I'm not sure there is a sender in the stock tank. There is no fuel gage. I also don't know how much room is required for the mechanical pump and if there were clearance issues. The motor has the coverplate...

    '78 FJ40 with 350 SBC and Holley Blue Fuel Pump Issue

    One of the many POs did the 350 SBC swap into my 78 FJ40 and installed an external Holley Blue fuel pump with regulator. I was having an issue where the pump would not always turn on, but seemed to respond to a thump from my hand and would then turn on. I assumed the brushes/conductors were...

    Speedometer only sometimes works, replaced cable, worm wheel worn??

    Did you get that gear yet? Curious if it solved your problem. I pulled mine today and the gear looks good, but the cable was pretty rough. Unfortunately, the cable they sold me is too short since I have a chevy 350 + toyota 5 spd with an AA on it. I need something about 24" longer, so I'm...

    Speedometer only sometimes works, replaced cable, worm wheel worn??

    Unfortunately, I'm in need of similar help (not providing it). My speedo is dancing, gets stuck at speeds I've never hit, and generally is making a heckuva racket. I'm wondering if yours was doing any of the same stuff. I purchased a new cable (not installed, yet), but am wondering if it's a...

    Stock lift & tire size

    All, I have a new-to-me 78 FJ40 with lift and 35's. I'd like to get it closer to stock...using as a towed and 2nd vehicle, mostly gravel, camping, etc. The pics show what is currently installed. What are the specs on what would allow 33 BFG ATs? Probably looking for different wheels, as well...
