This is long and I apologize.
TLDR: Can people with a known 17 gallon tank or a known 14 gallon tank measure the depth of the fuel tank at the midpoint of the tank about where the fuel pump hanger/fuel inlet hose is? Fuel pump hanger depth from a known tank would work too I guess. Thanks
For the gluttons with nothing better to do than read about my idiocy, the long version.
Well, I have found myself in a pickle of my own making. While changing out a noisy fuel pump (1986 4Runner DLX) in hopes of curing my overnight loss of fuel pressure I twisted the high pressure hardline from the fuel pump hanger. I sneezed while undoing the very tight connection and slipped. This has led me down a long twisted road and frankly I am confused.
I found a used fuel pump hanger at Rancho Toyota Recycling from a 1987 SR5 4Runner for $90 shipped. A local guy wanted $180. I bought the one from Rancho. It was in good condition, but needed some wiring repair, no big deal. It was then that I discovered that there were two fuel tank options. I found there were a 14gal/56L tank and a 17gal/65L tank option and I panicked as I discovered the different sizes needed different fuel pump hangers. Anyway, I convinced myself that this was a DLX-SR5 difference and since I alway add about 12.5 gallons when riding on empty I assumed I have the 14 gallon tank and that I mistakenly bought a hanger for a 17 gallon tank.
Why don't I just put in a 17 gallon tank? Years ago I found an 89 SR5 4Runner in a junkyard and one thing I pulled was the fuel sender. My assumption being that since it was out of an SR5, it must be for a 17 gallon tank. I PM'ed @pappy who in my Mud searching has done the 14 to 17 gallon tank swap to confirm the parts needed and started looking. The local recycler who wanted $180 for the fuel pump hanger would sell me a complete 17 gallon tank, fuel sender and fuel pump hanger and all brackets and skid for $350. I'm thinking I can recoup some of this by selling my extra hanger that I just bought and my used tank/sender/twisted hanger. I did the deal.
I get to work and start the process of pulling my tank. As soon as I remove my twisted up hanger I see it is the exact size of the hanger I bought from Rancho. I start getting nervous. I then pull the fuel pump hanger from the tank I just bought and it too is the same size. I'm starting to feel stupid and really confused. I know that the different tanks had hangers of different depth. I measure the depth of my new fuel tank and the one on the truck and they are the same size. The depth of the fuel tank at the midpoint of the tank near the fuel pump hanger/fuel inlet hose is ~14.25" (not including the skid plate). I'm pretty sure that the different tanks are the same dimension except the 17 gallon tank is deeper.
Houston, we have a problem and WTF!
1. I could have fixed my shenanigans for $90. I am using the hanger I bought from Rancho right now.
2. Is my assumption about DLX-SR5 tank size BS? It seems probable now.
3. Do I have a 17 gallon tank, and I just assumed empty was empty, hence the 12.5 gallon fill ups? Should I just see how far I can go? I've never had the low fuel light come on. I assumed it didn't work because I swapped in an SR5 gauge cluster and there was a missing wire.
4. I assume that fuel senders are different between the two tank sizes. Is it possible I have a a 14 gallon sender in a 17 gallon tank?
5. I definitely bought a tank of the same dimensions. The shady seller told me it was a 17 gallon tank that he confirmed by VIN. Did he lie or make a mistake? I haven't talked to him yet. If he didn't lie, I'm hoping that he will be understanding and if not refund my money at least let me trade for some stuff like wheels and a rear axle that I would like. If he did lie/make a mistake I'll go into the conversation a little differently.
I am pretty sure I am missing something very obvious so any insight would be appreciated. I am super confused.
PS I have a nice quiet fuel pump now. The O/N loss of fuel pressure seems better, but not completely resolved.
