Just installed my tank everything looks good except not a huge fan on how its mounted with only the 2 J hooks I’m going to have to fab up something better to hold the tank in place

Just installed my new M1A1 yesterday, everything went well except the tank install itself. The j bolts were bottoming out on the frame making the bolt angle too steep. Took about 1/3 inch off the j bolts and the install went great. Love not having to worry about rust! Thanks Wild Horses for the fast shipping and the great product!

Very tight fit- but looks/works great. Very well made, ran a 400 mile cruise right after installing and had no issues at all.

I've gone through two of the other brand 23 gallon tanks and the stainless version is by far the best. Quality is superb. I bought the tank, skid and EFI version. Skid plate is far beefier than I excepted. One install recommendation, test run the fuel pump bracket all assembled before putting it in tank. Use a 5 gallon bucket and 1 gallon of gas, smaller jumper cables from battery charger to pump, fire ext.. I use a supply line output with valve so I could test the pressure and glad I did, leaks at fittings and hose clamps. Hose clamps just needed to be tighter, brass fitting leak at brass supply fitting needed pipe thread compound with TFE found at ACE hardware. The hi tack would not seal, TFE did, works great. By doing this test you also know its primed, it works, no leaks, ready to go. Thank you WH for this product.
